Hopefully a simple one...
Took the whippet for its first ride tonight (from new) - coming home on the paths the back wheel shit the bed a wee bit. I noticed I couldn't take a backwards pedal stroke as the cassette wouldn't turn backwards and the chain would just hang. Filthy night, but get the wheel off and it looks like the freewheel is binding to the axle (if they're the right words) in one direction can can't be freely turned by hand. Stick it back on and ride it - feels awful but get it home.
The wheel is one of those on-one xc affairs - never used one before. Is it just a case of the hub being done up too tight maybe and needs the locknuts backed off a bit? Any ideas would be appreciated. Cheers.
