Rear Dropout too wide?

[DoctorWeir]

Greetings,

I posted a while back regarding an issue with XD cassette resulting in chain rub against dropout when in smallest cog. The dropouts on my bike measure out at 142.85mm. I'm questioning whether the 0.85mm is big enough of a tolerance issue, that it would lead to missalignment of the rear wheel and consequently the cassette being too close to the seat/chain stay?

If so, what is the best way to proceed?

Highly doubt the .85mm extra space would be enough to cause the cassette rub. What's more likely is either the dropouts themselves are misaligned, or the seat/chain stay junction is not built or designed properly to provide enough space for the chain to pass through when on such a small sprocket.

Would contact Yeoleo or whoever sold you the frame and get a replacement if possible

No matter how wide your spacing is, rub is caused by the hub/freehub/cassette positioning.

The axle stub isn't sticking out far enough, so either the cassette isn't fully threaded onto the freehub, the spacer is too thick, the freehub isn't fully seated or the axle stub/adapter is too short - now you have to find out what it is.

Normally yes, but remember the Supersix Evo 3 had issues with 10t rub because the seatstay was fractionally too fat. Nothing to do with dropout spacing obviously but still a frame issue.

Once you install the hub and tighten the thru axle your dropouts will only be spread as wide as your hub. Manufacturers tend to err on the side of too big with dropouts (+2mm/-0 give or take) otherwise you’d have to pull them apart to install the hub.

Is there any chance you're using an XDR cassette on an XD free hub?
