Hi, My hubs are startin to squeak and grind a bit. 2 and a half years with no service! i would do it myself but looks like i need a special tool for 'em.
So i'm goin to take them to my LBS. Any idea what they'll charge? Any rough estimation. just so i know how much wonga to take with me.

cheers!

The Cerit is similar if not the same insides as the Onyx hubs. The tools for the rear is just a pair of cone spanners. You will find it possibly just needs a clean. But if the bearings do need renewing then it will cost whatever the LBS charges.
