I have 32h hubs with Mavic Open Pro rims on my road bike. They are getting old, and will need to be replaced before too long.
I originally got those rims because I wanted maximum comfort for mile munching. Now I don't do as many miles, but I might one day do some road racing. Would it be worth getting a slightly deeper rim - Mavic do one at 30mm.
I'd still need 32h of course so they are unlikey to be much more aerodynamic I suppose, but they could be a little stiffer to help get my phenomenal power on the road/support my lardy arse.
