Hello All,
First I will apologize as English is not my first language and still learning it a lot.

I purchased new wheels from Mavic and replaced freehub body with ED11 to support my Campagnolo groupset cassette. This installation was no problem except now when I try mount the wheel, the drive side axle is much large to fit into the dropout

It is very obvious to me, even with measuring tape that the drive side mount is about 1mm larger diameter than non drive side. Is this normal? Even if I thought to try and force it that it might not be possible without damage to the dropout or frame.

The non drive side axle fits fine, front wheel fits fine. I attached some photos to show:

Example, drive side does not fit
Example, non drive side fit OK
Final I show you the installation on drive side, maybe I have made an error?



Thank you so much for any advice you can give me to riding again

Is it possible that one end of a Mavic hub is miss machined? Sure. But first I would want to measure or otherwise confirm before I made any decisions. Have you reversed the wheel to see if the, now driveside end in the left dropout, fits? A simple measurement of the two ends will say a lot more then we can, many miles away from your bike.


Did your old wheels have threaded axles? It's not uncommon for smooth/machined axle ends to be closer to the, usual, 10mm spec then a threaded one. It's also not uncommon for drop outs to need a slight dressing with a file to fit an axle. Andy

I'm not certain but I believe there are two different sized bushings available for the driveside. Ask the shop you bought this from or contact Mavic. Should be an easy fix. Your English is very good so no worries.

That doesn't look like an axle end. It doesn't have the knurling of the left side that grips the dropout.

Is it possible this is piece that an axle end cap fits over or is used inside the hub? I don't think it is an axle end at all.

Your English is very understandable.

One lesson: we would say "The drive-side axle is too large to fit..."
The word "too" is an intensifier, meaning more than enough, more than can be handled. If you drink too much beer, you feel bad the next day.

Your rear slots should be 10mm. I just measured a rear Campagnolo Shamal Ultra wheel. The axle diameters were 9,9 mm (DS) and 9,8 mm (NDS). If you have 9,9 NDS and 10.9 mm DS axle diameters, I think that the axle is improper. Contact Mavic.

That said, your rear dropout may be small. If you can accurately measure the slot where the axle goes, and it is too small (that is, less than 10.0 mm), you may be able to use a metal file (picture below) to carefully increase the slot size. Be VERY careful to keep the slot parallel. Or have a bike shop do this.

In any case, the rear axle diameters should not be 1mm different.

Hmmm... I agree. Here's a picture of a Kysirium, and you can see knurling (ridges) on the nut. Is the wheel assembled correctly?

Is that cap just on backwards?

I think that cap is the one in the upper right that has two narrow ends. It needs to be turned over so the knurling faces out.

WizardOfBoz

That looks like the answer.

BTW, OP, are you really in Moldova?
