Hi I am getting a new bike soon, a p2 carbon. I race triathlons and its a perfect fir for me. Next summer I plan on doing time trails and I would like to learn more about race wheels. I have looked and looked. My biggest question is what kind of difference will the hed stinger 50 be with the hed stinger 60. I know the rim is deeper, but is there a point when the weight has more neg impact than how deep the rim is. also at what depth does wind start making it difficult to handle? thanks alout for any help or websites posted!
