You may have seen a T7 on Monkeyboys' latest report. I did get new Exel / Bartuless wheels from Rally Raid. I found this setup excellent.
Yep, its certainly an option, Central Wheels will do it but the front rim needs changing, and then reading accounts from people it works for some and not others. You can buy Haan wheels or Alpina or Kineo (about £2K++) but to me it seemed like I was paying to fix something that shouldnt need fixing.
I wanted smaller lighter touring bike that suits the larger framed type. It is capable of being that but its a compromise because its trying to be an on road bike with off road capability.
