Touring rims then, like Mavic A719, the benefit of being able to run 32c for example at a much lower pressure than you would run them, as well as reducing the likelihood of puncture on the same size rims as well, even 25c work very well with the wide touring rims.

And if you're nearly 100kg, I'd stay clear of 23c, for your weight that's a bit too small.

I'm more than happy to listen to advice on the subject. I know that there is a strong movement towards wider rims at the moment.

However, I must have ridden close to 10,000 miles in the last 2.5 years - almost all of it on open pros on 23mm tyres (admittedly spread through different bikes and wheels). Many of those would have been with a weight 105kg+.

Ive blown out the sidewalls on a few gatorskins, but not before they'd done their duty. Apart from that I've no complaints.That said, if youve got any technical refs on tyre width for fatties, I'd be interested to read them.

as I mentioned, these wheels will rarely see any heavily loaded touring. quoted weights for the a719 have them about 25% heavier than open pros. is there really a big improvement in stiffness or rolling resistance that would offset the weight penalty?
