Because the frame on Trish's Mukluk is too small for a frame bag, we were looking for a cheap and easy way to mount a rear rack on the bike. Luckily the solution was hanging in the garage on her old mountain bike in the form of a Topeak Explorer with disc mounts.
By cutting off the disc mounts we were able to gain the clearance needed to get around the 170 mm hubs. It's amazing what a little work with a hack saw and a dremel will do.
The struts only had to be spread a little and it bolted on perfectly.
We had to extend the extenders to make them reach the mounts on the seat stays. Not the prettiest solution, but it works.
Plenty of clearance above the tire......
......and on the sides. I may just have to get one for mine.
