I've got PDW fenders on my roller, I had to drill out the axle mounts to fit my Phil rear hub. This was a massive pain in the arse, but mainly because I didn't have a good way of clamping the mounts to drill them. once it was done they've worked fine for a couple of years now.
For those with mudguards on their rollers here, how have you gotten around the lack of mounting points?
Have ordered some problem solvers but not sure how best to deal with the axle attachment points — pclips?
