I have a question about dropout spacing. I have a line on a very simple road frame with 135mm dropouts (I’ve only built up/ridden road bikes with 130mm dropouts). I’m putting something together from my spare parts bin to park on a direct drive trainer. Should I have any concerns about running a 10 speed setup on a non-disc frame with 135mm dropouts? Thinking about potential chainline issues with a compact crankset and 10 speed cassette. Novice question I’m sure. Thanks in advance!

Which trainer? Wahoo has 130/135 spacers. The chainline is not significantly different

It’s a 2018 Kickr. I may put wheels on the bike one day, but that’s not in my plans for anytime in the near future. Right now just want a sturdy frame that can handle all the sweat and rocking around but still perform well enough for trainer duties.

okay, it will work, you just use the spacers correctly. All the differences are taken up on the non-drive side. This is true for wheels as well, the spacing between the cassette and the drive side dropout is the same independent of dropout spacing.

Great! Thanks for the help!

What is the frame material?

I tend to prefer stuff to fit nicely, and have built up a set of road wheels for 135mm.

Howver, if it is a steel frame, you can probably safely run it with 130mm wheels.

he's not using a wheel, the trainer takes the place of the rear wheel. The trainer he's using has a spacer that works for 135mm spacing. I read the instructions and didn't really understand them, seems like you flip it for the different widths. Okay, I see it now, the trainer axle is a tube and the spacer fits in that tube with a shoulder. Flip for 130/135 spacing at about 1:24 in this video
I have a vintage bike on my kickr. Very low investment. It has good chrome, so sweat hasn't been an issue at all. Although I keep an old t-shirt above the place I'm most likely to sweat. I used to use camelia oil on it, I should probably reapply. I also swapped QR skewers, my bike has chromed horizontal dropouts and I kept riding the bike off the trainer. Fortunately didn't hurt myself or my bike

Thanks again for the help. The bike frame is aluminum with a steel fork. It’s close to the geometry of my regular bike, and my only hang up in pulling the trigger was the 135mm dropout spacing. I have extra 130mm wheels, so while it would have been nice to be able to put wheels in it in case the other bike goes in the shop it wasn’t necessary. I imagine it will just become one with the Kickr.
