Just doing a bit of experimenting with some cross tyres on my 29er, Main photo is a bit blurred, I had just washed the bike and the camera was a bit steamed up!
As you can see there is plenty of clearance at the front and back. The tyres wouldn’t seal tunelessly so I have run a road tube in them…without any problems so far. I have been doing a local CX evening series on this bike with Specialized renegade tyres, I will keep these cross tyres on for tomorrows race to see it it make any difference to the rolling resistance/my position. Its not really a fair comparison as the previous races have all been held on a rock hard dry circuits and tomorrow race looks like it will be wet and slippery.
I will report back.
