Hi,
As some of you may recall I posted on here regarding chainline issues with the Genesis Flyer when running a fixed sprocket on the flip-flop hub.
I sold the Flyer, it was too small anyway... and have just bought a Lemond Fillmore.
Lovely ride, love it so far, but again, I am having the same problem. Brick Lane stuck on a fixed sprocket for me and the chainline is off!
It's not quite as bad as the Flyer was, but it's still off. I've measured the distance from centre of hub to teeth and there's at least 1cm difference between fixed and freewheel sides.
I'm beginning to think that when manufacturers spec flip-flop hubs on freewheel bikes, they don't think about chainline on the fixed side. It certainly seems that way! It does seem weird that a flip-flop hub would give different chainlines. I thought the whole point was that you could quickly switch between them!
I'm tempted to sod the fixed thing and just run a freewheel until I need a new rear hub.
Anyone noticed this? Am I just being picky?!
John
