Rennen RayceLite gearing was developed due to the needs of an insane BMX dad (George Costa) pursuit of an extremely light micro-mini build. Looking to cut every gram possible for his 3yr old (Rayce’s) bike it was clear there was a better solution.
Raycelite gearing is the lightest mini gear in the world (37T, 43grams). Like all Rennen gearing products, only 7075-T6 is used and significant 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.
Due to the extreme weight reduction design, we do recommend that this product carries a weight limit of a 70lb child.
Compatible only with: ANSWER MINI CRANKS ARMS and SPEEDLINE MINI CRANKS
