Thanks
Stace  :daumenhoch: :daumenhoch:

give us a shout if you get stuck.


thing to remember with profiles, is that the bearing cases never fully sink into the frame on one side, because the spacer stops it doing so. this is correct. dont forrce it all the way in or you may damage your bearings. softly softly catchy monkey.

Why not grinding a bit the spacer tube to have the cups properly fitted then ?

its only about 1mm. i suppose you could grid the tube, but you risk getting it uneven, which will make your bearings run like a sack of shit.

I had the same problem, so I used a piece of 22mm copper tubing.

It fits great, and is easy to cut to exact size you want.
