SQUAMISH, British Columbia (BRAIN) — OneUp Components is now offering narrow-wide chainrings for Shimano XT M8000 and MT700 cranks, designed to be used with Shimano's new 11-speed offroad groups.
The rings save 35 grams and $20 over the stock XT (SM-CRM80) single-ring, OneUp said.
They are made of 7075-T6 aluminum and are designed fr a 49mm chainline. They are available in 30T, 32T, and 34T and fit Shimano XT M8000 single-ring and double ring armsets and MT700 double-ring armsets . They retail for $55.
The OneUp rings for the XT cranks include bolt shims allowing users to re-use their stock Shimano bolts, without compromising ideal chainline, whether they are converting a Shimano single- or double-ring crank.
OneUp recommends the single rings be paired with an 11-45 cassette. The company's 45T expander sprocket is compatible with both M8000 XT and M9000 XTR 11-40 11 speed cassettes.
