Shimano Chain 116 links w/o end pin CN-HG901-11 11-Speed

Product Information

Cable friction remains more of an issue for rear shifting over the long haul than with Campagnolo or SRAM though and the shifter internals are worrisomely exposed. Cyclo-cross riders in particular will take issue with the big gaps in the bottom of the hood through which the ratchet teeth are clearly visible. Even on the road, spray from leading riders invariably ended up inside the shifter and tended to gum up the works. Interestingly, Shimano have done the same thing that many riders criticised SRAM for including on their first-generation Force group – eliminated the trim position for the outer chainring. However, we think it unlikely anyone will complain this time around. Though we were always able to get first-gen Force to work as intended, front derailleur setup is more straightforward on 7900 and there is no cage rub with any rear cog when in the big ring. Bravo. Basically, if the point where the two chain ends meet is the ‘end’ of an outer link, add three links (left image). For Shimano chains in particular, pay attention to the text and logos on the chain. These will be on one side of the chain only, and that side should be facing out (away from the frame). The front upper section above the lever pivot is fully enclosed, an aesthetic departure from previous years.

With development of the new groupset focused primarily on road disc brakes, the rim brake R9250 levers are not wireless. You’re almost there, but there’s one more thing to keep in mind. Some chains are directional. They’ll either have an arrow ‘ printed’ on them, or something that indicates the inside or outside of the chain. Have the two chain ends meet at the large chainring, and then add four or five links, depending on the zero point shown in Shimano’s image below: If you’re using one of the older Di2 derailleurs, the chain sizing method depends on the cassette installed on the bike.

Each lever is powered by a CR1632 coin cell, claimed to last around 1.5 to 2 years of riding. Riders can choose to run their levers wired if desired, which apparently has the side-effect of increasing battery life by around 50 per cent. s braking performance is definitely superior to 7800 with a snappier and more fluid lever feel plus noticeable improvements in power and modulation. Many readers have lamented the revised cable pull ratio on 7900 – thus sullying the idea of mixing groups – but if that is what was required to get this level of performance, so be it.

The new lever feels more substantial, with a significant increase in girth (roughly 165mm vs 140mm at the base), while the flatter and longer top distributes pressure more evenly for better long-term comfort. The slightly canted and broader carbon fibre lever blades are slightly easier to reach from the hoods, too, and a reach adjust mechanism is hidden within.Have the two chain ends meet at the large chainring, and then add two or three links, depending on the zero point shown in Shimano’s image below: Wireless communication takes place between the levers and the rear derailleur, with the latter always ‘on’ and listening for signals. The main battery is claimed to last for around 1,000km of riding, while the coin cells in the levers should manage 1.5 to 2 years.
