Freehub removal

mikeq

Hi all,

Have a Specialized Allez 09, this has shimano drivetrain components.

Any site I have read talking about removing a freehub says to use a 10mm alan/hex key. Definitely too small for the freehub on this bike.

The wheels are Alexrims S500, anyone know what size alan key I need?

Thanks
Mike

A bigger one

The 10mm allen key is for Shimano hubs, and while your bike may have mostly Shimano components, Specialized use unbranded hubs on this bike.

So unless someone on here has done the same job on the same bike, you'll have to experiment with different allen keys or ask a Specialized dealer.

There are some hubs around that need a 12mm allen key and some that need the allen key inserted from the non-driveside.

Thanks for the replies.

I have emailed Specialized to find out. And the only reason I am asking is because I'm really struggling to get an allen key bigger than 10mm, over the past week I have tried Edinburgh bike co, B&Q and 2 branches of Halfords, none of them have allen keys in stock bigger than 10mm

So was just trying to find right size before I order one online

Good source here:

if they get back to you with the 11mm allen key size dont forget that that is the same size as 7/16th which tend to cost less.

but again brand/model of hub will help. (Pics will help).

thanks for the further replies/advice.

As 2alexcoo says these are unbranded hubs that Specialized use on this bike. It was the first thing I looked for.

sorry about hijacking your post...... but can any one give me some details how to remove a campagnolo freehub ,,, as it is jamming (sticking) when freewheeling.....it needs to be replaced with a new one, which i have ordered.....the wheels are American Classic

Separate allen keys are indeed a pain to find in big sizes. You want a set of these from Halfords:



Can't think of the proper name for them, allen sockets maybe? 3/8" drive with a shortish breaker bar should be fine

just got response from Specialized, so posting here for future reference for anyone else

"Hi Mike

Thank you for your e-mail. The Allen key you need will be either an 11mm or 12mm depending on which hub is fitted. Both will unscrew from the non drive side of the hub.

I hope this is of help."

Mikeq,

Before you go out and buy both, try putting your 5 and 6mm allen keys together to see if they fit (i.e. 11mm) or the 5 and 7mm (12mm), You won't be able to remove it like this, as the torque required is too much.

Then go and visit Murray's Tool store on Morrison Street (opposite the Exibition Centre). He will either have one, or should be able to source you one.

I had the same problem, mine is an 08 Allez, and I used the Alex rims as my winter wheels. Stevie at Wheelcraft in Livingston reckoned for the money to fix it, I would be better of with a new wheel, as the specialised own brand hub was pretty rubbish and wouldn't last long.
I bought a new winter wheel from JMC in Bo'ness (Revolutionary Bikes) with a Tiagra hub and omega rim for about £60. I use the old Alex wheel on my turbo trainer, as you don't need to worry about a freehub for that.

What size key did you need in the end? I have the same issue.

Thanks

My 07 Allez came with Jalco rims and a Specialized hub.
The rubbish freehub skips without warning and I almost had a bad accident in Putney.
I removed it with an 11mm Allen key from the drive side. The key was £5 delivered from a supplier on Amazon.co.uk. The hub bolt was really tight so I used an old steel seat post get more leverage.
I've ordered a Shimano 2200 hub for £10 and will try and fit it's free hub. The bearings etc may also be useful. If the freehub isn't compatible I'll attempt to rebuild the wheel with the 2200 hub. The wheel is rubbish, but I have other projects to spend money on so keep spend on the commuter to a minimum.

I don't think it will work, the only thing that matches on the two freehubs will be the splines for the cassette.

Sorry just came back to this thread. It needed the 11mm and is removed from the non-drive side of the wheel. It all just became a pain in the butt so I put new wheels on the bike, a set of Fulcrum Racing 5s, best thing I ever did.

Well that was until I bought my Cannondale Carbon Synapse 2 weeks ago

Thanks. I couldn't get it off in the end so had to buy a new wheel.

American Classic hubs are constructed unlike no other...beautifully simple but perplexing to the unitiated. Have a look on the AM Classic website - there's a small grub screw on the locknut / collar at the end of the wheel spindle, loosen it and then give the spindle a sharp tap - the whole wheel spindle will slide out and the freehub simply lifts off to expose the pawls and cam-plate mechanism. You probably don't need to replace the freehub, but there may be damage to the cam-plate or pawls themselves or it might just need a clean-up. Depending on what model of hub you have, but current models require a 19mm conespanner to adjust the bearing load for re-assembly.
