The VBC, variable bolt circle, crank set is both an elegant and durable addition to your road bike. The crank set is designed as a traditional double ring crank set, however, it can also be paired with one of our single speed chain rings and be set up as a single. The crank is designed with a low Q factor, 142mm, that allows the arms to sit close to the chain stays effectively giving one more direct power transfer into each pedal stroke. The outer ring is innovative in design with a spline system interfacing the ring with the crank set.
Strengths: Stiff and beautiful. About the only crank that has infinite adjustabily with rings. I us a 26/40 for my mountain bike. There are only a couple of cranks that will do that.
Weaknesses: Poor shifting between rings
Bottom Line:
Great. Can shift through all rear gears on either chainring without much crossing
