Why do you think you need deep section carbon race wheels?
Seriously!
Wheels is my business, so I’ll not mention brands 🙂
What do you mean by “race wheels” is the first big question, TT’s, Crits, Sportive, league style road racing? – if the latter, do you generally rise with the pack, or long breakaways, what types of course? All these questions come into play before deciding the right wheels to use!
Deep section rims carry a significant weight penalty, but a big aero bonus – if you’re leading off the front on open courses then thats maybe acceptable, but if you’re in the pack, then its all disadvantage – the broken up, eddying air reduces the aero effects, and you’ve got added weight, in the rim, giving a less responsive, heavier wheel, throw in the disadvantages from side winds and it starts to get messy.
full carbon? huge, huge loss of braking performance in the wet!
Clincher or tub? tubs great if you’ve got a support vehicle, good luck if you’re fixing it yourself by the roadside (same goes for road tubeless!)
How hilly? the weight/aero balance cancel each other out dependent on specific courses. Whats your average speed – again the weight/aero balance, it sits somewhere around the 20mph average.
What frame – the important factor is the airflow through the entire bike, not just the wheel – I’ve seen data showing deep section wheels slower on some frames, as the wheels spits the air at high velocity into a big, fat downtube – while the air from a shallow rim, spoked wheel breaks up the airflow and actually gives a lower drag coefficient through the “wheel, bike and rider combo”
So, its a hell, hell of a lot more complex question that “which wheels”!
