I've just bought a Mavic Allroad Pro wheelset and I want to convert the rear hub from 12x142 to 10x135 configuration. I bought the 10x135 adapters (highlighted in red in the attached image, it's a section of Mavic manual) and I need to remove the original endcaps. I tried pulling them by hand but they don't move at all and I'm afraid of damaging something by using too much force. What is the correct procedure to remove the endcaps? Anyone knows? Couldn't find anything on Mavic site about this.


Unfortunately you have to use force to get those guys off.

If you can wrap the cap with a rag and then grip it with a pair of pliers you should be able to pull it straight off. It will take some effort.

  • I somewhat agree. In my experience, these caps will usually come off with a screwdriver pried underneath each side, lifting millimetre by millimetre on each side. This worked on my Mav' wheelset and caused no damage. Your method will work, but sounds a little barbaric. If you have no intention to reuse them, your method will certainly be the fastest route. – yollooool Mar 10 '18 at 21:06

    @yollooool fastest simplest method. I've done it dozens of time here at the shop. If you're careful and don't scratch it, this way is superior. – BillSkiCO Mar 10 '18 at 21:11

Wrap end cap in a couple layers of insulating tape, tightly bolt on a correct size p clamp (the clamps you use to fix racks etc to frames without mudguard eyes) use mole grips on the p clamp, gently pull off cap, hey presto!!
