Electric ​mountain bike​ review

Shimano returns to revolutionize the world of the bike entering without fear into the mountain with its n ​ ew electronic group XTR Di2​ and opening a new era in the way of interacting with the changes of our bike.

The great novelty goes far beyond a new command and electronic changes. Welcome to the future, this is the new Shimano XTR Di2.

A rough way, the electronic changes are much ​more powerful​ than the mechanics of all the life, they are ​more precise and faster​ , and

all this by pressing a button (pulsador). The engine that includes both derailleur and rear change has a power that will give us 100% whatever the condition (mud, rain...). a ​ dvantages of c ​ ycling everyday One of the great innovations inherited from the road Di2 is called E-tube​ , and among many other functions consists in the possibility of programming the push buttons completely​ . To give an example, we can program the change button so that when you leave it pressed the chain will raise or lower as many gears as you wish, even at the speed you want, or program the right button as if it were the left or vice versa. All this with the guarantee that the change will respond regardless of the condition, without any problem of cable wear, shirt or mismatch of the changes.

Another of the great novelties and the great brain of the new Shimano XTR that for the first time see the light is ​the Synchro Shift technology​ . The new brain of the XTR will make our life easier (or not), and will allow us to forget almost completely the left button (deviator). As we go up or down crowns, ​the diverter will go from one dish to another ​and the brain will adjust the rate by

raising or lowering a pinion to equal the same and not notice any pull. bicycle​ maintenance For example, if we go up a slope in a medium dish that gets steeper every time, and we go up crown to crown manually, before we get to use the medium plate with the last crowns crossing the chain, the derailleur will automatically go down to the small plate and its Once the rear derailleur will lower one or two pinions to equal the cadence.

All this i​ s also programmable​ , being able to say to our changes in which pinion the diverter will lower or raise a plate. Simply connect the control unit to our computer to program the different areas using the E-tube platform. This also allows us to update the software of our XTR, benefiting from new options or correcting errors.

We can see the performance of ​Synchro Shift​ in the following video: The Synchro Shift will therefore ​allow us if we wish to forget the deviator button​ , even dismantle it and control all our changes with the right button.

The new display​ of the Shimano XTR will give us information about the status of the same, such as the use of the battery, the pre-confirmed program that we are using, the gear we carry and also adjust our suspension, in this case it is ​compatible with the new suspensions FOX electronics​ . Through the display we can also switch between "manual" mode, we change both pine nuts and plates to our liking, or Synchro mode, where t​ he derailleur comes alive and adjusts our pedaling​ . The two "zones" that we have

previously configured with our computer are also adjustable from the display. All this can be done in progress.

The D ​ i2 battery​ is identical to the road system, and can be inserted into the seatpost or any "hollow" tube of the bike (SM-BTR2) or externally anchored to the bottle cage for example (SM-BTR1). Its autonomy is guaranteed, although there are no fehacientes data since it will depend on the type of terrain through which we circulate, the cyclist, etc. etc. On the highway, it guarantees around 2000 km of autonomy.

The XTR Di2 is somewhat heavier than its mechanical brother​ , but if we dispense with the derailleur handle and use it with two plates, the weight is almost identical.

- External battery (SM-BTR1): 71 gr - Internal battery (SM-BTR2): 50 gr - Control screen (SC-M9050): 30 gr - Shift lever (SW-M9050): 54 gr - Front derailleur (FD-M9070): 115 gr - Rear change (RD-M9050): 289 gr

Mountain bike ​training plan​ ​endurance The new Di2 rear derailleur has been updated with the Shadow RD + technology, which in addition to the two positions of external adjustment of the spring, medianet an allen key can adjust the tension of the same. Check it in this video: Another of the great advantages of the new electronic group lies in the e ​ limination of cables and sleeves​ , not only because we h ​ ave to

adjust the change​ due to wear or lack of tension in the wiring, but also because of the flexibility and the possibility ​of cable guidance "Now yes" completely internal​ . The future lies in the suppression of these cables by wireless technology, but Shimano is still leery about the issue. The delay in the appearance of the new XTR Di2 is given by the necessary test time that Shimano has used for everything to work perfectly, with more than ​20,000 km of tests and tests​ , and we are sure that in the future and after the tests of rigor, the cables will be history.

The development of the XTR plays with a ​pinion 11-40​ being able to vary the plates between 28-38, 26-36 and 24-34, also available for the most "ruteros" in three courses.

The new S ​ himano XTR Di2​ will be available in stores before Christmas, and with a price yet to be confirmed, yes, something more expensive than the current mechanical Shimano XTR.
