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

Post a picture. But maybe a skewer that sticks out more will work. Take a look at the KK skewers for a possibility.

You could probably get a piece of aluminum milled to sit on the skewer for the trainer if there is a metal shop locally.

show pictures....are you using the skewer supplied with your trainer?

Pic of your dropout would be nice. FWIW, my Pegoretti Marcelo has a huge flange around the rear dropout but I have no problem using it on my CyclOps Fluid trainer. Here's a pic from Pegoretti's site:



You can clearly see the flange on the NDS where the chain stay and seat stay join. DS is the same.

What skewer are you using?

found this pic of the "Ascent Adjustable Magnetic Trainer" and it looks like the NDS side skewer cup is grossly oversized:


Although, simply using a basic dome-capped metal skewer instead of whatever fancy-shaped one came on your bike might let you use this trainer correctly, I'm thinking many other trainers on the market will have less bulky attachment points.

I got a different set of the cups that hold the skewer for my Kurt Kinetic trainer to accommodate a similar problem. Maybe check with the trainer manufacturer and see if they have anything like that?

I have the same trainer, but a different bike.

Make sure you use the skewer that came with it and just rotate the nds clamp so that the bigger end of it is on the bottom.

Personally, I'd ditch the trainer, keep the frame, and ride my road bike on the road.

Well that choice is not quite available for everyone. It's -30C without the wind here right now...

EDIT : Well, he is in Seatle, it's probably not that bad there...

+1... I have that trainer as well.

Suggest getting a Craig's List bike for a few hundred bucks to dedicate to the trainer.

It's warmer on the summit of Mt Rainier than it is in downtown Seattle. Anyway, it's not so bad that I'd just give up, but to each his own.

Uhhh... when did they install a weather station on the summit?

I think that would do it, I will look into it. I figured all cups were about the same size & so I didn't consider replacing them. The Kurt Kinetic NDS cups appear to be much smaller. I will see if there's a way I could install something like that on my trainer.

Here's a picture that shows the flange:


I am using the skewer that came with the trainer (although it's not the one shown in the picture, because it's currently on my dedicated trainer bike).

I already have a dedicated trainer bike (Vitus 992 that's slightly too small for me), but I want to be able to use my main road bike on the trainer so I can free up some space (& some cash for more bike projects).
