I have a 09 Specialized Allez Sport. The paws on the freehub are sticking. The wheel is Mavic CP22 rim with a Specialized hub. The LBS says the wheel cannot be service. Does this make sense? They said they would call Specialized about replacing the wheel, but I doubt I will get resolution on that front. I just want to get this fix. Money is not the main issue. I thought the Freehub could be replaced. A $50 repair. If I need new wheels, thats a $250 repair.

How long have you had the bike? if it is a '09 it may still be under warranty. certainly have the shop contact Specialized, they may have an issue with that hub.

as for the wheel why can't the shop service it? I am not familiar with these wheels but I would think the freehub body should come off. you may have nothing to lose by trying to squirt soem triflow between the body outside and inside.

$250 for a set of new wheels is not a bad price. you can get cheaper ones, and if you ride alot it never hurts to have a spare wheel set or at the very least a spare rear wheel.

On my Easton EA90SLX wheels I had an issue with the pawls sticking. I was able to disassemble the hub and clean the pawls which took care of the problem. YMMV.

I've replaced the freehub on a Shimano hub, pretty simple.

I agree the replacement of the hub is simple. I guess thats why I have 3 bikes so you always have a back up. I will wait for colder weather when riding time winds down and see if the free comes off.

I just replaced two Mavic CP22/Specialized wheels under warranty.

The hubs are Joytechs. Not the best you will find, but they are serviceable.

I believe the Joytech freehubs share a lot of common parts with Odyssey BMX hubs. If there's a BMX shop in the area, they can probably disassemble and clean up the mechanism for you. As with freewheels, you don't want to use thick grease on the pawls, heavy oil is best.

So if they are Joytech, replacing the freehub needs to be a Joytech? Or can Shimano be used?

What I've seen is that the gap between the freehub-body and hub isn't sealed very well. So water & dirt finds their way in and you'll need to remove the freehub and service it about once a year. If you can find a thin O-ring that fits in between, this might be a good way to seal it.
