Rennen RayceLite gearing was developed due to the needs of an insane BMX dad (George Costa) pursuit of a extremely light micro-mini build. Looking to cut every gram possible for hi s 3yr old (Rayce's) bike it was clear there was a better soultion. Raycelite gearing is the lightest mini gear in the world (37T, 43grams). Like all Rennen gearing products only 7075-T6 is used and sigificant machining is employed to greatly reduce the weight. We aim to improve every product that we design at Rennen and this self extraction feature is the latest development to come out of the Rennen Design Lab. PLEAST NOTE: 70 LB RIDER WEIGHT LIMIT. SPECIFICATIONS Sizes: 34T-42T Rennen/Answer/VSR/Turn3 crank compatible Works with single spd thru 11 spd chains Show more
