Shimano Dura-Ace 9100 groupset review: Veering ever closer to |, Shimanos latest Dura-Ace group is a big step forwards in some ways, but not in others, The new STI Dual Control levers offer a drastically different shape from Dura-Ace 7800, Last years dip in the top of the lever has been replaced by a flatter and wider perch, The new carbon brake lever is canted outwards a few degrees for an easier reach from the hoods, Shimano use an annoying cover plate that must be removed in order to adjust reach or replace the brake cable, Shortening the reach leaves an unsightly gap an oversight atypical of Shimano, Derailleur housing now runs beneath the handlebar tape and can be run either in front or behind the bar, Running the derailleur housing in front leaves a sharp edge at the rear of the lever though, The shifter internals are dangerously exposed to the elements, The new Flight Deck computer is far easier to install just remove the top of the shifter and bolt on the new bits, The new crankset is undoubtedly one of the stars of the group and is now offered in a compact version as well, The deep-profile spider arms and incredibly expensive outer chainring yield superb front shifting performance, The heavily relieved spider keeps the weight down, Shimano retain last years arm attachment method, The revised front derailleur cage is wider than before yet shifts superbly and also runs rub-free in the large chainring with no need for trim, Revised front derailleur pivot geometry requires more cable pull at the lever but yields a lighter feel that requires less effort, Rear shifts are as impeccably smooth and precise as before, The carbon fibre pulley cage is curiously flexy but this doesnt seem to affect shift performance, Braking is superb with the new calipers and revised cable pull ratio, Aggressive yet careful machining sheds weight while retaining stiffness.
