Right so I got myself a Control after my Yaabaa snapped.
Running 18:15 with Trialtech Lite chain, HS33s with TNN mounts, try-All 2 bolt booster and Hole rim/Der Kaiser rear tyre.
My problem is that with the correct tension in the chain (and enough room for the tyre), the mounts do not line up with the rim. The mounts could do with being welded 5mm lower. With the TNN clamps at their limit adjusted all the way down, the pads rub on the tyre about 2-3mm.
So, 2 ways around it - Move wheel forward in dropouts and use 74 Kingz style tensioner on the chain, or cut out the top part of the brake clamp to give more travel.
Anyone have this problem/got around it? Any problems with cutting the top part out of the brake clamp?
