Re: poor handling at top speed
Junster, you might be on to something about the fork. I will first try regular tubes to see if that fixes the problem. And as for the sprocket, I forgot to mention I am using andy's top hat adapter mounting the sprocket directly to the hub where the disc rotor would mount. So the sprocket is not on the spokes and it is true.
The only place I compromised on this build is the fork. It is a suntour low end fork. It is 90mm travel which is minimal. It seems pretty solid. Next time I go out when the shuttering starts I will glance at the fork.
BTW I still have the original rigid fork that came with it if need be. I put the suspension fork on since I plan on doing quite a bit of off roading. (I bought a 38T sprocket for the road and a 54T for off road)
Thanks for your help guys!
