Hey chaz, we should ride on wednesday when my bikes sorted. I've told you, I'd rather improve drivetrain. Your freewheel skips like an underage schoolgirl. Buy a tensile, they're pretty ace, and you'll save yourself a few quid Edit : You'll need to go FFW and buy a fixed rear sprocket . Just realised bud Sorted : Onza screw on = tenner. Cranks = 52 quid Freewheel = 35
