  • Tyre sizing.
    Question asked by Keith Blundy on 23/12/2022 15:59:37
    The FX 6 is designed as a "comfort" road bike for those that are not concerned with speed but with a higher level of comfort in mind. Fitting a narrorew tyre will be 32mm as a recommended minimum. Pedals can be sourced after market or as an add-on as all pedal threads for adult bikes will be the same size thread regardless of type or thread.
