First impression.. it's certainly a lot harder work than the roadie but to be expected with the extra weight and big offroad tyres and fine cruising along at her speed. The brakes are much better than when I tried some mechanical discs in their early days and have good modulation instead of just being on or off like they where back then. They really pull the wheel to the side though. Don't know if it's in the fork, wheel or combination of the two and I don't notice it in the ride but it's visable and with much wider tyres or under really hard braking I think the tyre would come into contact with the fork.
Well scored, sir.
I'll wager that the front brake issue is a combination of the fork and wheel. They probably aren't quite stiff enough to counteract the braking force delivered by the disc. It's unlikely that the wheel will torque enough to contact the fork but anything is possible I suppose.
This issue is why you often see QR15 front axles & hubs on the more high spec bikes. Instead of a 10 mm threaded tube and a traditional QR, the axle and QR are combined in a 15 mm tube that goes through the fork leg and wheel bearings and screws into a nut in the fork leg on the other side. Tighten up the QR cam on this axle and you have a very stiff front end that is very resistant to twisting forces from the brake and rough ground....
