  • Which pedals
    Question asked by Nigel on 11/11/2024 10:21:16
    If you are using trainers, you`ll base you desision purely on a pair of flat pedals. Metal ones will be sronger but could ruin the traed/sole of your shoes whereas plastic ones and more comfortable on your feet as they will a little bit of flex to them howver, most designs can be slippery when wet and will have a lower life expectancy. As far as the fitting goes, the fittings are universal regardless of the pedal type.
