One-by customers can choose XTR chainrings between 30 and 36 teeth, but the narrower gearing spread of the 11 x 40, eleven-speed cassette means that riders may need to keep a couple of chainrings in their toolbox to match their gearing to the task at hand. Calculating out Shimano XTR’s lowest-available, 30-tooth-chainring option fetches a low gear of 1.33:1 and a high of 1: 2.73. Compare those figures with the options from SRAM and Shimano that we covered earlier in this segment, and they indicate that hills will be harder to climb, or you will probably be spun out on the flats. Shimano’s one-by gearing options are clearly intended for racers and stronger riders who will probably choose the biggest chainring that they can comfortably push and then suffer with whatever low gear is left when the big climbs arrive. Note: The Q-factor is wider by 10mm on Trail 9020 Cranksets | 168mm than Race 9000 Cranksets | 158mm.
