Quickpro ER ONE max measured tyre size?
« on: May 16, 2026, 05:25:13 AM »
I have an ER ONE with XMCS wheels internal 26mm with GP5000 30mm which measure 33mm, need new tyres and wondered if the 32mm Conti 5000 str will fit assuming it maybe comes up to around 34-35mm measured?

Anyone know the measured max, spec say 32C so maybe a 32C Conti will be fine but it will blow up large on my wheels?

The frame should fit 34mm measured easily or even bigger. But the limiting part is the front derailleur as the chainstay is short. So depends what groupset you're using. I will run 32mm GP5000 in the rear on 25mm internal measuring 34mm. Ultegra di2 12s I suspect there won't be many mm to the di2 cable which is the closest part. I'll measure next week as I build it up.

yeah I've measured with the 30mm in there which measure up at 33mm and there is loads of room but the ultgra di2 cable looks like the closet things, think it may still work so will probably just go for it
