By my calculations, (&I could be wrong) a 26" x 2.1" tyre is approximatly the same diameter as a 700C X 28.
The 26" being 680mm Dia Outside Diameter
The 700c X 28 being 668mm Outside Diameter
So my question is.....
Will the 26" tyre, being wider than the 700c fit into a Cannondale Frame.
My wife, I and two kids are looking at extended touring in 2014. We like the Cannondale Tandems however they don't make a MTB fframe anymore. So we are left with one with road bike geometry and hardware. I don't really wish to tour with 700c wheels as i have read it can be difficult to get 700c tyres around the world in various spots.
I have looked at the Co-motion but wanted to go alloy frame.
Any advise here would be greatly appreciated.
