OOI, why R45 over AR46? I’ll be running 25 or 28c tyres.
Clearance. Intended for an older frame, possibly MGOF. GP5000 in 25 should = c. 26mm and I can then see if there's the possibility of fitting 28s. But I'm worried that the ARs won't fit the frame and could make calliper choice tricky...
I have a pair of those R45 rims and 25mm GP4ks came out at 28mm on them. 23mm GP5k or 23mm Vittoria Corsas end up at 25mm. FYI.
