• When the bikes were deliverd they had quite a varied gear range on them. We did what we could at the time to make them all similar. Now a year has passed, chains are due to be replaced so it would make sense to change the gearing over at the same time.

    Why 78 on the smallest bikes..? At the moment there are only a handful of bikes with Youth gearing. This would allow for every bike within a youth session to be equally geared.

  • Cool thanks, that's interesting - do you have any idea how far the average bike has been ridden?

    I'm going to stick with 48:15 on my bike as that's pretty close to 84".
