How to Convert 10 Speed Wheels to 11 Speed Wheels

I am upgrading my groupset and wondering what it will take to get the wheels I have now work with an 11 Speed upgrade.

I have one pair of Mavic Ksyrium Elites and a pair of Mavic Cosmic Carbon wheels. I've been told that these can be used with the 11 Speed cassette as is since they have the spacer that Mavic wheels use. Is this true??

My other wheels are Bontrager rxl. Will they require a new free hub, or will I have to have the rear wheel rebuilt??

Thanks in advance for your help.

RD

You already have all the shifters for 11?

Campy or Shimano ? I think in most cases Campy type wheels will accept an 11 speed cassette. But Shimano wheels will need a longer freehub body.

Yes, but OP is asking whether the Mavic freehub is already longer. It does have 2-3 mm of spacers for use with various freewheels.

Try a Shimano/SRAM 11 speed cassette on your existing "8/9/10 speed" Mavic freehub body, it should work (not sure what spacer configuration you'll have to use to get it right). 8/9/10 speed Mavic freehubs are wider than others, hence the thicker spacer that's typically used with them. True 11-speed Shimano/SRAM freehub bodies are 1.85mm wider than 8/9/10, but an 8/9/10 speed Mavic freehub body should be wide enough.

so if my Bontrager wheels (that were OEM on my Trek) are 10 speed, can I just buy another freehub? or will they require an entirely new hub and free hub?

Your Bontrager hub was probably built by DT Swiss, it may have that name on it. If it is DT Swiss you can contact them by e-mail, tell them what you are trying to do, include the hub serial number, and they can tell you if the freehub can be replaced with an 11-speed freehub.

I have the same issue. Just called DT Swiss regional distributor. He said the part number is: HWYABX00S2775S They also suggested an LBS to do the swap and make the part order as they don't sell direct. I just called the LBS and they are ordering the part. It sounds like a fairly straight swap. There are special tools required and you have to know which parts to keep when you dis-assemble and re-assemble, so not DIY for me, but YMMV.

Mavic freehubs were 11-speed ready 20 years ago.
