There have been some decent articles written though that wheels will be better (maybe stronger) when axle length is increased to allow for the additional spacing needed. I don't know I only have a couple hundred miles on my current wheels and they seem perfectly strong to me

With all this though, would I let something like the number of cogs direct which group to buy... not in my case. I bought Shimano DA because I prefer the style of shifting and brake performance to the SRAM, if I were to buy SRAM or Campy it would be for the same reasons if I preferred the performance of one over the other.

Good luck I'm sure you'll enjoy any group you get!
