Performance Wheel Parts

Hi

I’ve just finished building my first wheels, and really enjoyed it. They were a set of 36/32 tiagras on touring rims, laced X3 for touring/audaxing, so pretty conventional.

I would like to upgrade my performance bike’s wheels to something a bit stiffer and more responsive than the current Shimano 500s. I’m 6’6″ and find that when I’m really powering the bike, the wheel flexes and I can hear the rear derailleur clipping the spokes occasionally. I suspect the only way to prevent this is to get a stronger wheel.

I’d also like to try building these ones myself! So, where can I go about getting more performance directed rims & spokes? I’m not out to race (yet) so I don’t want anything too fancy, and my budget isn’t huge. I’d like to get some deepish rims – 30mm – and maybe 28 rear 24 front. Has anyone got any suggestions for the rim, and for where I can purchase from?

Thanks
