Take flight with the eeWings from Cane Creek. These titanium cranks are designed to keep up with the rigorous demands of the most aggressive trail and enduro mountain bikers – though they will benefit any rider who puts a premium on durability, stiffness and weight. The eeWings and the included CNC aluminum bottom bracket preloader are the ultimate in stiffness and durability while only weighing a mere 400 grams – in the same weight range as premium carbon cranks but 20% to 30% stiffer. In fact, we have such confidence in the eeWings’ quality and durability that we are backing the cranks with a 10-year limited warranty.Weight: 400g (415g with power meter),Materials: Titanium arms, spindle, crank bolt,Available arm lengths: 170mm, 175mm,Preload adjustment: Cane Creek CNC Machined 7075 T-6 Aluminum,BB Compatibility: 30mm spindle only.
