Tubs

At my level, I'll use Challenge tubs (which have polyester casings) rather than Dugast or FMB, unless I find bargains (like the pair of Rhinos I got for £75).[/QUOTE]

What's your reasoning Ste_S?

Are these really good then? Have seen them about, do you use the criterium?

19mm would be too uncomfortable?

I imagine that they would be fractionally more aerodynamic, possibly slightly lighter, and with less rolling resistance due to a smaller contact patch, but also less forgiving.

^All assumptions, however.

I have rocked the 19mm and the 22 and the 19 wasn't noticeably less forgiving...
