I'm never to "tire-d" for TE

[Mimosa]

The GP's are good tires.

However I remember from another forum that the brand Vittoria have a slightly larger diameter so they are easier to get of and on the wheel and change the inner tube. This would help during your first tries at changing the (inner) tyre. Though the wheel is also a significant element in how easy you can get the tyre on and of. For instance it is said that the DT Swiss rims are hell to get a tyre on.

I train on Vittoria Rubino Pro tires, they are simply the best and cheap to come by (last set was about 15 dollars per tire). I haven't really had a punture with them. Only once did I have a flat but that was because I hit a sharp edge hard so the rim dug into the inner tube.

For competition I am still doubting between the Michelin Pro2, Schwalbe Stelvio and Vittoria Corsa CX. The michelin because I allways used to race on them, the Schwalbe because they seem to have a good rain grip and the Vittoria because I now train on that brand and am happy with them .... *sigh*, all those choices.

Oh and go for the 23C. 25 is my opinion to big and 21 to small.

And yes trainers are hell on your tyres, so either by a cheap set of tyres for the trainer or get one of those special trainers tyres.
