Do your brake calipers open up wide enough whilst having the quick release closed for the wider wheel too?
PhilDAS-
Good point. I've got R8000 calipers which are compatible for 28mm outer rim width so that shouldn't be an issue. Do you think the tyre clearance will be ok?
The alternative is the R45 rim – 17.9/25mm. Whilst I prefer the profile of the AR46 it might be a safer bet than waiting 6 weeks for a wheelset that might be too tight?

Hi all. I'm wanting to order an LB rim brake wheelset – preferably the AR46 – but have some concerns re. tyre clearance on my '04 Merckx Team SC frame.
I currently have 25mm GP5000's mounted on Cero AR30's (17.9mm inner/22mm outer) measuring at 27.5mm width. This leaves me ~8mm clearance either side at the brake track and ~4mm clearance from the tyre to chainstay.
The AR46 rim is 21mm inner/28mm outer. According to the LB 'Actual Widths' chart GP5000's will actually come up smaller than my current wheels at 26.54mm.
Whilst the clearance from the braketrack to the chainstay will reduce from 8mm to 4mm the clearance from the tyre to the chainstay should actually increase to ~5mm clearance.
This should be fine, right?
