Hi,
trying to help friends fix their rubbish student bikes which all have internal epicyclic gear hubs... never dealt with these.
The recurring problem with these hubs seems to be the gear slipping off causing the whole system to free wheel without the chain turning the wheel. It happens when changing gear and can be rectified by shifting the gear a bit - but it makes the bikes pretty unridable.
Everyone seems to have these problems with the old bangers they've been sold... and the LBS are repeatedly charging £££s for fixing...
Anyone know how to fix these?
Thanks a lot
Ben
