They’ve never had much presence in MTB, but Stronglight have been making excellent cranks for years and these funky beauties have really impressed us.
The broad crankarms are full carbon around an alloy crank interface with a rubber window in the middle (road cranks are hollow) for absorbing shock. We didn’t really notice it, but they’re stiff considering the weight. Broad shape means they scuff ankles more than most but the tips and leading edges are protected with stainless steel cuffs. Switchable pedal inserts give either 170mm or 175mm crank lengths. We’ve been really impressed with the quick shifting ceramic Te?on chain rings too, which are still going strong after a fairly tough year. Even the lightweight ISIS BB is holding up okay and this overall durability makes the high price slightly easier to swallow.
