Why does my front hub need tightening after every ride?

felix.london

It's a Specialized Stout and after about 25km it needs tightening.

Any ideas?

Locknuts not tightened?

wordnumb

If you're sure that you're adjusting it properly maybe try a little threadlock on the locknut, but this shouldn't be necessary.

The Rookie

If the locknuts aren't locked off against the cone, then its exactly what can be expected to happen!

Just checked an old one lying around - think they are cartridge not cup and cone?

felix.london

Right, sorry - stupid question time;

where's the locknut?

felix.london

I thought the Q/R was the lucknut? :?

The Rookie

No, the QR has a nut, not a locknut....

Cartridge means they are sealed units and I can't get to the bearings?

cooldad

Try the nut opposite the QR nut.

The Rookie

Or the nut holding the bars.......

Felix, you need to be more specific about which nut you mean...

I have spesh stout that are cup and cone.....

Cartridge bearings can be replaced - as a cartridge.....

Check the photo - I've got the Q/R nut and then the nut that you tighten to adjust the hub (too tight wheel wont spin - too loose wheel is wobbly)

There ain't no lock nut so guess that means they're cartridge but that still doesn't explain why the fekking wheel is coming loose

cooldad

Make your mind up, is the wheel coming loose or the hub loosening.

Come on guys, throw him a bone. We all had to start somewhere.

Felix, those are cup and cone bearings, not sealed cartridge. And I would strongly advise carefully removing your disc rotor before your next step in this learning curve.

And remember to use a cone spanner for the cone. A regular spanner won't fit in there.

on closer inspection it does seem the wheel is coming loose and the hub is ok as removed the wheel and put it back and now it seems fine

But Q/R lever was closed nice and tight - so can't see how it could loosen.

50km ride today up a and down a mountain - think I need to go to bed and look at it in the morning

Knackered Q/R skewer?

Alright - fair enough - so where's this elusive lock nut?

The lock nut is right there, in the middle of your picture. The thing with 2 flat sides.

Yeah right I get - the penny has finally dropped! :roll:

I need to buy a cone wrench 13-14mm or 15-16mm?

cooldad

Most come with all four sizes in one - look on Ebay - few £s. Buy two as you need to hold each side.

felix.london

Right got it. Cheers

Probably should have looked at this in the morning with fresh eyes and saved everyone a lot of time!

Thanks for your help guys

cooldad
