It's not really relevant to my question - I just want to know if a G2 fork will ride ok on a non-G2 frame - but here's a very condensed version of my problems with my bike and it's components. And yes, the 4 sets of brakes *is* at least partly a bike problem, as they were deemed "incompatible with the frame" by both Avid and Trek.
I have lost confidence in this bike and just want to move on. Can someone tell me if I can use the G2 fork on a non-G2 29er? Will I notice a difference compared to a non-G2 fork?
I bought a 2008 Hifi Plus 29er with Juicy 3s in March 2009. The rear brake failed within 4 months and was replaced with an identical Juicy 3. From then on, the bike had terrible vibration/honking/howling noises. I tried different pads, different rotors, different sized rotors, but couldn't make the noise go away. Realigned the caliper, check the torques of all bolts & suspension points, had the wheels double checked... Nothing worked.
I then bought new brakes - Elixir 5s, thinking the problem was the brake. The noise went away for 1 ride, then came back full force. Took it back to the shop and they discovered a crack in the frame (in the chainstay joint behind the bottom bracket). Got a 2009 Hifi Pro 29er as a warranty replacement, and moved all the components over.
The bike was *almost* quiet for about 3 rides, then while on a mt bike vacation, the vibration & noise came back full force again. I tried attaching various weights to the caliper, as many people have found that to fix the problem, but it did not work.
I was in contact with Gary Fisher tech support and Avid tech support but no one would take ownership of the problem. Luckily I have had good support from two LBS's & eventually the local Trek Rep.
I happened to meet the local Trek Rep at a bike event and told him my story of woe. He got me a new set of Shimano SLX brakes, which made everything good for a few months.
Now the bike is making creaking noises and cluncking feelings again, and has started to vibrate and howl again when the rear brake is applied.
Additionally, prior to the frame/brake vibration issues, I had to have the fork rebuilt twice within 2 months of buying the bike, due to a faulty rebound seal. I realize this is not a Fisher specific issue, but as a component spec'd on the bike, it contributes to the experience.
