Four differences to expect when switching from summer to winter biking

By Sam Friedman

your bike

SFRIEDMAN @NEWSMINER.COM

Winter is the best time of year for bikers who like riding over snow.

Fat-tired bikes got their start in Fairbanks with a wider tire developed in the late 1980s known as snow cats. The sport continues to grow in Fairbanks, attracting new cyclists each winter with the promise of year round biking and hundreds of miles of trails.

To help fair-weather cyclists who are thinking about learning to cycle during Fairbanks’ longest season, I spoke to some experienced snow bikers about making the transition from skinnier tires to fat.

There may be some walking involved It doesn’t take any special skills to ride a fattired bike. Despite their ungainly appearance, first-time riders report they handle much like mountain bikes.

But riding a bike in snow takes some adjustment. The fat tire’s huge

ERIC ENGMAN/NEWS-MINER FILE PHOTO surface area helps keep the bike from sinking into snow, to a point, but while the bikes open new snowmachine trails to bikers, there are limits to the amount of snow the tires can float over. Walking and pushing the bike is unavoidable in some conditions.

Tom Moran is a veteran of the White Mountains 100 race north of Fairbanks who skied the race before converting to fat biking a few years ago. It’s possible to have fast conditions for an entire fat

bike ride, but conditions can change quickly, especially on longer rides and in more remote ones, he said.

“Different trails get different amounts of use. At some point, there’s always a possibility that the trail is going to go from great to terrible,” he said.

“A lot of it depends on who used it last. If you’re behind mushers, it’s usually great. If a paddle track snowmachine comes through, then all of a sudden a trail that was wonderful and firm is all of a

sudden all turned up and you can’t really ride on it.”

Although the snow can slow down the ride, it also cushions it. That was a big selling point for Christopher Knott, who organizes the Icicle Bicycle fat bike races each year for Fairbanks Cycle Club. The hard ground in winter transforms soggy swamps into fast trails and snow helps smooth out some of the bumps, he said.

Expect to pay more for

Fat - t i r e d b i ke s a r e new and trendy, so generally a retail purchase of a winter bike will set you back more than a mountain bike or a road bike.

A $1,500 price tag is a pretty standard minimum for a bike that’s relatively lightweight and durable, according to bike shop staff at Goldstream Sports and Beaver Sport. But a lot of decisions go into picking a bike so prices range widely.

Fat-bike prices have dropped in recent years as the bikes have become more common. Once the exclusive domain of boutique manufacturers, they’re now made by major bike producers like Trek and Specialized, Moran said. Moran also cited a $1,500 retail price point as a typical minimum for a quality fat-tired bike purchased new.

Fat bikes aren’t universally considered the most expensive style of bike frame.

Knott considers fat bikes the least expensive option when consideromh all features, such as fancy brakes

Bikers need warm clothing to protect themselves from the cold and from the wind chill they generate as they pedal. But because cyclists are exerting themselves, they should expect to wear lighter, more breathable clothing than snowmachiners.

B e av e r S p o r t s b i ke shop employee Phillip Sommerfeld recommends that customers start winter biking with a similar level of clothing as they would wear for cross country skiing. Bikes can break down, so it’s important to have warmer gear with you if you need to stop pedaling and change a flat.

Cold weather gear for hands and feet is especially important. Many winter bikers use pogies, large insulated mittens that attach to the handlebars. They allow winFATBIKE » 4

Many benefits of vitamin D pills still untested

By Romel Wrenn FAIRBANKS MEMORIAL HOSPITAL

Historical Perspective

Vitamin D has long been known to be important for bone health. The association between industrialization of Northern Europe and the softening and weakening of bones in children (rickets) was made in 1822 (1).

In 1921, Hess and Unger exposed children with rickets to sunlight and demonstrated significant radiologic improvement in the children’s rickets. By 1900, 80-90 percent of children living in northern Europe and in northeastern United States had evidence of rickets (2).

In 1931 the US Department of Labor published the pamphlet “Sunlight for Babies.”

Vitamin D became so popular in the United States in the 30s and 40s that dairy products, soda pop, beer, hot dogs, custard, soap and shaving cream were fortified with the vitamin (1). Increased sun exposure and vitamin D supplementation eradicated rickets within several years (1). Fear of vitamin D toxicity led to a ban of fortifying foods with vitamin D in Great Britain.

Vitamin D stimulates reactions within the cells in which it is produced, and stimulates

reactions at nearby cells, and reactions at distant cells.

These endocrine, paracrine and intracrine actions of vitamin D lead to its skeletal and nonskeletal effects.

Vitamin D recommendations

The best source of vitamin D is adequate sunlight. In Fairbanks, the UV Index averages below 3 from September to April. It averages 3-5 during May to August. We cannot produce vitamin D from sunlight when the UV Index is below 3. It seems reasonable for adults to take a vitamin D supplement from September to April. Recommendations for vitamin D and calcium supplementation for infants and children should be under the guidance of the child’s health care provider.

Vitamin D and calcium supplementation should be under the guidance of a physician to avoid toxicity.

Nonskeletal actions of vitamin D Although there’s an established link between vitamin D deficiency and several diseases including cancer, cardiovascular disease and diabetes, studies have yet to show that taking vitamin pills lowers the risks of these disease.

also protect hands, but they do make it harder to operate the bike. Goldstream Sports store owner Joel Buth lists them as an essential piece of equipment for enjoyable winter biking.

To carry the extra gear, many bikers mount bags on their bike frames. A trend Moran has noticed

Fun winter science experiments to try Reprinted from our 2015 Guide to Winter because all of these look like fun.

By Robin Wood RWOOD@NEWSMINER.COM

R

ambunctious children can make surviving winter difficult for kids and adults alike.

When cabin fever strikes, it’s good to have some backup activities to give everyone a breath of fresh air.

Staff at the University of Alaska Fairbanks’ Museum of the North provided some fun experiments to try with your children, all with minimal equipment, most notably a meat or candy thermometer.

Insulating properties of snow and fat

Jennifer Arseneau recommends exploring the difference in temperatures between the air and snow, and the insulating properties of blubber.

For the first experiment, simply use a thermometer to measure the temperature of the air, and then measure the temperature under the snow, which is scientifically termed “subnivean.” Snow traps lots of air, and that makes it an excellent insulator. New snow is often 90-95 percent trapped air, according to the National Snow and Ice Data Center.

“That’s why the subnivean is a great environment for many active winter animals, like voles,” Arseneau wrote in an email.

If you want to play messy, pull out the shortening. Fat, or blubber, also makes a spectacular insulator. Put disposable gloves on your kid and coat their hands with shortening, then add the second larger glove to contain the mess. Dip both the bare and blubbered hand into ice water.

“You will quickly feel the dif-

Their mother, Stephanie Morning, told them she would keep the trampoline up during the winter as long as they kept it clear of snow. ERIN CORNELIUSSEN/NEWS-MINER FILE PHOTO ference having a layer of blubber can make!” Arseneau wrote.

Another experiment in the spectrum of losing heat is to compare the thermal mass of two different sized “animals.”

Get two jars, one small and one large. Fill each jar, according to size, with hot water, and monitor the temperature with a thermometer.

Before starting, ask your children to hypothesize which jar will stay hot longer. The ratio of surface area to mass is much lower for the large jars, meaning it will stay warm longer.

Salted snow

The effect salt has on the low temperature of water can be examined multiple ways.

Put snow in a bag, take the temperature and feel it with a bare hand. Then add a few tablespoons of salt. Salt lowers the freezing temperature of water. Keep an eye on the thermometer because the snow “will get very cold!”

Gabrielle Vance, museum staff, wrote.

Alternately, put salt in regular tap water, then see how

cold the water gets before it freezes.

Bonus: Use the lowerfreezing temperature provided by salt to make ice cream.

Put one tablespoon sugar, 1/2 cup milk and some vanilla extract in a sandwich-size Ziploc bag. Insert the smaller bag with the ingredients into a gallon-sized bag. Inside the larger bag, put 2 tablespoons rock salt and enough ice cubes to almost fill the container. Seal shut and shake about 20 minutes, until the inner mixture is frozen.

Snow vs. water

Measuring the water content of snow is a fun and visual experiment. Gently scoop snow into a bucket or leave one out during a snowstorm — don’t pack the snow down. Measure and record the snow depth.

Then, bring the bucket indoors, let the snow melt and again measure the contents. In many cases, you’ll need 20 inches of snow to produce one inch of water.

How to properly maintain your pellet stove

By Cold Climate Housing Research Center staff

Q: What type of maintenance does a pellet stove need?

A: Are you thinking of purchasing a pellet stove or boiler? Pellet appliances have some advantages over their cordwoodburning counterparts — including less maintenance, as pellets produce less ash and particulates

than cordwood.

However, you still have to clean a pellet stove or boiler. A clean stove is more efficient than a dirty one, because it will allow more air flow and the heat exchanger will transfer heat more efficiently.

Also, a clean stove will last longer because the components will wear down more slowly. Finally, clean stoves are safe stoves, as removing buildup helps to prevent chimney fires.

Each pellet-burning appliance will come with an owner’s manual that explains a cleaning procedure and recommended maintenance schedule. In general, though, cleaning a pellet-burning appliance is similar to cleaning a wood

stove. If done regularly, it shouldn’t take more than 15 minutes. Before cleaning your stove, remember to turn it off and let it cool down.

First, remove the ash from the burn chamber and ash pan. Some stoves will also have an ash trap located in the exhaust.

You can use a small shovel or an ash vacuum. Avoid using your household vacuum because ash and soot can ruin it.

Next, scrape the soot off of the burn pot and heat exchangers. The heat exchangers are usually a series of tubes in the firebox the hot air passes over.

You can use a wire brush to scrape any soot off of them.

If you see any “clinkers,” or

pellets from the stove, auger or hopper so they don’t collect moisture and rust. They might also settle down over the season and stick to the bottom or sides of the container.

Servicing a pellet appliance is typically done annually just before the heating season. A heating professional will thoroughly clean the entire appliance, including the pipes.

They will also inspect seals, lubricate any moving parts, and perform diagnostic tests to ensure the stove is working properly.

They may adjust the controls to ensure the stove is operating efficiently. If the appliance is used a lot, STOVE » 9

Many users clean their stoves each time the ash pan is full. This will depend on both how often you use the stove and the grade of your pellets.

Premium-grade pellets have a lower ash content than standard or utility-grade pellets, so you don’t have to clean the stove as often.

In addition to cleaning, there are two other maintenance tasks: cleaning the auger tube and hopper and scheduling a service of the appliance.

Occasionally, when the auger tube and fuel hopper are empty, vacuum the sawdust so it doesn’t build up and block the feed system. At the end of the heating season, remove

hardened deposits, make sure to remove them.

Clinkers are formed from melted ash that then hardens and can block air pathways. While you do this, glance at the pipes and ensure they are clean so they facilitate good airflow.

If they are getting dirty, it’s time for a service. It’s a good time to check the hopper and auger, too, to make sure there are plenty of pellets and no blockages.

Finally, if your appliance has a glass door to the burn pot, clean the glass with a commercial glass cleaner.

This will allow you to see the flame when the stove is burning; it should be bright yellow or white. A darker orange flame means it’s time to schedule a service.

Maintaining wood stoves

Operation and maintenance 1. If you use an airtight stove, open the intake damper fully before you open the door. The hot unburned fuel gases can burn explosively if air is introduced too quickly.

2. Never burn coal and wood in the same stove. Clearances for coal stoves and the construction of coal stoves are different than wood stoves because coal generates higher heat.

3 . B u r n d r y, w e l l s e a s o n e d wood. The wood should be dried at least one year. This will reduce creosote deposits.

4. If you burn artificial logs, never poke it or burn more than one at a time. They contain up to 60 percent wax or Sterno and will burn extremely fast if broken up.

This will damage your stove and may cause a house fire.

5. Keep all wood, paper, matches or other combustibles away from the wood stove or chimney pipe.

6. When you reload your woodstove or start a fire, let it burn with dampers wide open for five minutes. This will help burn out creosote deposits in the chimney.

Do not start a hot fire if there is a layer of creosote one-eighth inch thick or more in the chimney pipe.

7. N e v e r u s e f l a m m a b l e o r combustible liquids to kindle or rekindle a fire.

STOVE Continued from 8 service may be required more than once a year. To know when to schedule the service, it can be helpful to track the amount of pellets that are burned between services for your stove (one ton? two tons?) and use that weight to estimate when the next appointment should be.

Home maintenance necessary before winter sets in This column first appeared in the News-Miner on Sept. 15, 2016.

The “Ask a Builder” series is dedicated to answering some of the many questions Fairbanks residents have about building, energy and the many other parts of home life.

By Cold Climate Housing Research Center staff

As winter approaches, it’s a good time to look at a fall home maintenance punch list before it gets too cold. In addition to a boiler tune-up and chimne y inspections, there are a few more details worth considering.

Now is the best time to make sure your roof system is in good working order. It’s not too late to replace shingles, add snow stops, patch l e a k s o r r e p l a c e a ny missing fasteners on metal roofs.

When the leaves are down, the gutters are ready for inspection.

In the spring, gutters clogged with frozen debris are virtually impossible to clean and can cause melt water to overflow and run down next to the foundation and into the basement or crawlspace.

Check the downspouts, too — they should be unobstruc ted, firmly attached and pointed to direct water away from the house.

While walking around the house, check the grade for drainage. Surface soils will remain unfrozen for a while longer, so it’s not too late to do any last minute dirt

A pair of skiers cross Ballaine Lake on a warm, wintry evening on Jan. 12, 2015. ERIC ENGMAN/NEWS-MINER FILE PHOTO work to ensure spring runoff is directed away from the house.

Inspect any heat traces to make sure they are in good (and safe) working order. Replacing heat trace now is a lot less hassle than a frozen waste or supply line in the winter.

If you have any concerns about the safety of a heat trace — particularly if it’s older — consult an electrician. A malfunctioning heat trace can be a fire hazard.

If you have an HRV

system, make sure all parts are in good working order. Alaskans tend to spend a lot more time indoors during the winter, and good ventilation is critical.

An inspection should include a look at the supply and exhaust grilles on the outside of the house — not just those belonging to the HRV, but also dryers, range vents and bathroom fans, especially if they are close to the ground where the intake can become clogged

with leaves, grass or other debris. If an exhaust damper is present, make sure it is operating smoothly.

Open up the HRV and examine the filters and the core. The cores can be removed and washed out if they are dirty. The condensate drain and drain line under the HRV should be free of obstructions; if a trap is present, it should contain water.

A properly installed HRV is designed to bring in and exhaust the same

amount of air. The system should provide enough fresh air to ensure occupant health and control indoor humidity but not over-ventilate, as excess airflow is simply wasted energy.

If you’ve never had your system professionally balanced and inspected, now is the time to call a residential ventilation contractor.

I f y o u ’r e p l a n n i n g any air sealing with spray foam, the cut-off temperature for most

expanding foams is above freezing, although a few brands may go lower.

Last but certainly not least, make sure your home has operating smoke alarms and at least one operating carbon monoxide detector all within audible distance of the bedrooms.

Snow built up on roofs presents a danger to structures This column first appeared in the News-Miner on Dec. 25, 2015.

The “Ask a Builder” series is dedicated to answering some of the many questions Fairbanks residents have about building, energy and the many other parts of home life.

By Cold Climate Housing Research Center staff

Q: When should I worry about the snow load on the roof ?

A: Snow loads var y across Alaska, from as much as 300 pounds per square foot (psf ) in Whittier to as little as 25 psf in northern Alaska. There are several factors that are used to

calculate snow loads, including the moisture content of the snow, seasonal accumulation and drifting.

The weight of snow depends on its moisture content, which varies depending on the conditions. The moisture content of snow ranges from about 1 percent to about 33 percent (water weighs about 62 pcf ).

Compressed snow — even snow that simply accumulates over time — will weigh more than freshly fallen snow. Fallen snow can also pick up humidity from the air and increase in weight.

You determine weight by using a measurement called Snow Water Equivalent (converting

inches of snow to inches of water by taking a cylindrical core sample of snow and melting it.)

You can find the daily Snow Water Equivalent (SWE) for different locations in the state, including Fairbanks, at the USDA Natural Resources Conser vation Services website (at www.wcc.nrcs.usda.gov/ snotel/Alaska/alaska. html.)

To calculate pounds per square foot, you multiply the SWE by a conversion factor of 5.2 (check out the formula here: www.ak.nrcs.usda. gov/snow/data). That gives you a snow load of roughly 12.5 psf. Keep in mind that this number is only designed to pro-

vide an estimate for the region.

Current building code in the city of Fairbanks calls for roofs to withstand a minimum of 50 psf, but homes built before 1991 were required to carry 40 psf and older homes even less. Mobile homes can be built to carry just 20 psf. Keep in mind there is no building code outside of the city limits. Roof snow loads can vary depending upon type of roof, roof slope and melting and re-freezing of snow and ice, among other factors.

Sloped roofs that periodically shed snow load present both benefits and risks. If snow slides safely onto open ground,

there’s no problem. But if that snow hits a deck on the way down, the force is multiplied many times more than its resting weight and can shear otherwise stable structures right off if they are not supported sufficiently. Or if snow slides onto a flat roof or other surface, its cumulative weight is magnified from that of normal snowfall.

Structures should be designed with overhangs or other features to offer sliding snow a safe path to the ground. The ability of chimneys or utility poles to withstand sliding snow should also be considered.

In addition, decks, sheds, greenhous-

es, campers and other structures built without permits or an inspection may not be able to handle much if any load depending on the quality of the workmanship. An underbuilt roof structure may also be at risk for collapse from imbalanced loading.

For example, if the snow slides off one side of the roof yet remains on the other, the roof must be able to withstand the forces working against the structure during a change in weight distribution.
