as you might get a set of second hand ones which are on the way out, not worth buying second hand ones, or bite the bullet and buy new ?85 not cheap
Nor have I mate, mines a track bike, I’m a bit ocd with things being 100% and it seems I’ve got ongoing Niggels with the thing. Want to ride it not keep repairing it.
mine might just be a lemon lol
