I got a used Scott Speedster S1 frame last winter and built it up as my primary road bike, but I has disappointed to discover that it is incompatible with my Ascent mag trainer. The rear dropouts on the Scott frame have a flange that prevents the skewer ends from seating in the cups on the trainer. Has anyone else dealt with this problem? Is there some other kind of trainer I could get that would avoid this problem? Seems like almost all trainers have this same kind of mounting system. I would switch to rollers, but I like the resistance I get with my mag trainer. Can add a picture of the rear drops if that would be helpful. Currently using an older bike on the trainer, but I'm hoping to get a trainer that's compatible with the Scott so that I can reduce the size of my fleet.

Thanks,
Evan
