Title: 1.25" tires on mavic ex 721s
Post by: ahconway on April 03, 2010, 11:22:49 PM

Hi! It's been a while since I've logged in here... Glad to see Everything's still humminalong nicely!

So here's. My question. Any reasoning shouldn't fit folding Pasela 1.25" tires to the mavic ex 721s onmy Raven AT? I've just done it and they look pretty skinny!

Thanks - Andrew

See http://www.sheldonbrown.com/tire_sizing.html#width (http://www.sheldonbrown.com/tire_sizing.html#width) for suggested min/max tyre widths for rim widths. I think your EX 721s are 559x21. So borderline...

You'll feel the bumps more... & your gearing will be lowered ( unless you change your ratios )
