I'm converting a Tune 190 hub from campy to Shimano. I've disassembled the hub but still need to get the left side end cap off and remove the bearings from the free hub. I really just need the special bearing. Can anyone tell me the best method for doing this?

I've seen the article on Adrien's website but unfortunately some of the pictures don't show up.

For the bearings having the Tune W-Mag tool kit is a plus.....if you are talking about the NDS cap, the one glue in the axle it's a pain to get it out.
Our service guy just hate it when he has to do the swaps and we don't have axles with the caps ready for installation.
They fix that cap with loctite (green).....it's posible to get it out but will require that you fix the axle somehow on a press without damaging so you can work on it.

Yes I know...you have to figure out their use. With the small cylinders you can tap in/out the bearings....you have to find the correct one.
For installation you need Green Loctite but we have great results with Tef-Gel....takes care of all the sounds but you do have to re-apply after some time.

Sorry to bring up an old thread.

Juan, I want to do the same. Was it successful? I want to go from Campagnolo 11 to Shimano 11. Or should I just use a Campagnolo 11 cassette in a Shimano setup instead?

It was a successful conversion. I was able to just reuse the existing bearing and did not need to replace it since it still fit smoothly. The Tune tools are very helpful once figured out.

BTW, Still using Ergon grips on my mtb since my 2008 surgery. :wink: :thumbup:
