Real Gussets instead of look-a-likes. With a regular tube joint to the headtube the main tubes are welded to the headtube first and THEN the box gusset is added, - so giving MORE weld points to the headtube than just a bigger area that a hydro-formed single tube joint can provide.
Ovalised tube tuning. Ovalised 7075 triple butted top tube optimises the strength in the fore & aft direction. As a tube increases in diameter so it increases in strength (and weight). The forces being applied to a frame tube are often greater in one direction. Ovalising a round tube effectively increases the diameter focuses the strength of the tube to counter the greater force (while not adding weight). Ovalised tubes to meet the greater forces gives a stronger and lighter alternative to simply using larger tubes. One of the highest stress areas on a BMX type frame is the headtube junction… and so the downtube is ovalised in the headtube area to increase the effective diameter and therefore strength in the fore & aft plane. However, unlike the top tube, the other end of the downtube has to also cope with the huge lateral forces generated from pedalling. The bottom bracket end of the downtube is ovalised the opposite direction to the head area, so reducing the lateral flex (and loss of power) from pedalling.
Forged Aluminium yoke. Solid 7075 Aluminium, forged and CNC finished, optimises the tyre and chainring clearance while maintaining low weight and low flex.
11/8” headtube. Traditional style, CNC machined push-in 11/8” headtube.
Twin Box Chainstays:
The “throw-in” self seating cartridge bearings may work well enough in hard steel frames and alloy frames with suspension forks or road bikes… but, we figure with a short rigid fork and small wheels… the headset can take quite a beating on a BMX race bike.
Box section Rear stays:
So… if your headset get’s a “headache” (other than just a bearing failure) – and we think it’s much easier to just pop out the old one and install a new one… same as we’ve been doing for years now.
Butted tubing.
A box with a central rib (making Twin Box) takes the high strength at right-angles to an applied force factor of a box… and adds another wall… so making the tube even stiffer.
Box section is stronger than round tube if the forces are at right angles to the sides.
7075 Triple butted Top tube and Down tube. Increasing the wall thickness of a tube increases the strength (and weight)
Bolt in cable guides. Our neat bolt-in guides allow you to choose left or right side (or cross over) cable routing.
Butting refers to increasing the wall thickness of a tube at certain points only (think of a Rifle gun butt.) e.g. Very few frame tubes fail in the centre of a tube. One of the higher stress points on a frame tube is at the areas where it is joined to other tubes.
Butting of the tube wall allows thicker material to be used at the high stress areas for strength, while thinner material can be used in the centre to save weight. Plain Gauge tubing is uniform wall thickness along it’s length. Double butted tubing has matched thicker walls at each end. Triple butted tubing has 2 different wall thicknesses at each end (to allow the tube to be better matched to handle potentially differing stresses.) Multi-butted can refer to tubes that have multiple wall thickness changes, depending upon the application. Seamless butted tubes are proven to be a refined and finely controlled production process in terms of tolerances of wall thickness and strength. (Conversely, “Hydroformed” tubes tend to have a less refined tolerance and have to allow an extra margin for the inconsistency of the process hence
more material has to be allowed to compensate for the increased tolerance and thus more unnecessary weight.)
