I'm selling my Surly hubbed wheel and a question has come up re reduction to 120mm.

I've emailed Surly but (unusually for them as they are normally quick) they haven't got back to me.

Would I be right in thinking it is simply a case of removing the 2 grey 'spacer' nut washers? See pic below

i dont think you can i had one of these hubs in bits and those spacer looking things are the bits that preload the bearings i think your stuck with 135mm

Check Velo Solo they do the right spacer kits.....I think.

I'm guessing that they're angular contact bearings, but if not you should be able to just re-space with the right thickness of nuts / washers.

Looking at the pics below, it appears that the main nut ie. the one facing the drop-out, is the same on both and the grey on mine is a spacer. Mine also appears to be missing the bearing covers!

I guess the only way to check is to remove it 🙄

If the surley 135 mm hubs are any thing like the on one 135 mm hubs (and from memory they are) the actual hub body and flange spacing is wider so you can't just remove some parts to narrow it down.

I've measured both (I happen to have an old PlanetX one as well) - Surly is 78mm flange width but the PX is aroun74/75mm.

All-in-all it's probably not worth the hassle for the buyer, especially with an extra 7.5mm of axle sticking out each side, so.....anyone want a nice Surly flip/flop free/free hub on a Rigida Chrina rim?

Surly have just confirmed it

No, you can’t space that hub down to 120mm. There are several reasons, but chief among them is that regardless of the dropout spacing, you cannot respace the chainline, and the chainline of a 120mm dropout frame will be narrower.

Thanks for all the input

I thought I could screw on a cog and lockring for a fixed/free - not realising that lockrings are different sizes........if anyone knows where I can get a lockring to fit I would be grateful as I have tried loads of different shops.

just keep hunting it's an old b.b lock ring is what you are looking for, although it's not reverse threaded / left hand thread so not secure like a track hub lock ring. However if you are running front and rear brakes it doe not matter if a fix cog comes loose plus you will not be putting as much back pressure on if you have a rear brake.
