I have had the good fortune to pick up a Trek 2011 TopFuel 9.9SSL frame and would like a recommendation on a front fork. I have been looking at various Fox RL 100 forks and am wondering about the various options - FIT cartridge, open bath etc. What is the standard and recommended fork for the 2011 TopFuel 9.9SSL in the Fox or Rockshox range? 9mm QR was the spec for the 2011 TopFuel and would suit wheels I have, but am also wondering about 15mm axles. I would appreciate experiences and opinions.
