 "answers_question": "Is a Gates carbon belt drive worth it on a commuter bike?",
 "text": "The Gates Carbon Drive replaces a metal chain with a carbon fibre belt. No oil, no rust, no stretched links. In theory, it's the perfect commuter drivetrain. In practice — after upgrading from the CDN to the CDX version — it mostly lives up to the promise.\nWhat's great: completely silent, zero maintenance, never dirty, lasts far longer than any chain. In Amsterdam's wet, salty conditions, a chain rusts and stretches within months. The belt just keeps going.\nWhat to know: belt drives require a frame with a split stay or removable dropout (you can't thread a closed belt through a frame). The initial cost is higher. And you need an internally geared hub — no derailleurs.\nWillem paired his with a Shimano Alfine 8-speed internal hub. The combination is effectively maintenance-free commuting.\nFrom Willem's cycling collection.",
