BearingProTools - Bearing Puller for Bicycles

This is a simple tool for removing bearings. I have the 12mm size, which works better. I couldn't get this one to grip the bearing tightly enough to extract it. The tool just falls out - even when done up very tightly using two large spanners.I think the problem is the cuts in the collet - the expanding section - are too short, so tightening the bolt can't expand the end enough to grip the bearing tightly. Compare with say a Sykes-Pickavant collet, which has slots nearly the full length of the collet - but is hugely expensive.It's a shame, because it's a great idea, nicely made, but just not quite there yet. It may work on a less tight bearing, and I'll keep it to try that in future, but I couldn't extract a Vision Metron freehub bearing (17x26x5) with this tool. I may try cutting the slots further down the body of the tool myself.

do no expect the bearings to be serviceable afterwards. This is because you really have to crank the nut down tight for it to stay in the bearing and it takes a good couple of whacks to get them out, this kind impact will cause the balls to dent the inner races and no amount of grease will ever make them run smooth again. (IMO you should not be re-greasing critical bearings like in hubs and BB`s anyway, once they go "rough" they should be replaced).

I bought the 6903 version to service the front hub on my Fulcrum Racing 5s.The tool fitted the bearing nicely, and I did it up snug/tight using an adjustable and a ring spanner. Then I rested my hub on a 41mm waste pipe coupler and using a drift and small hammer got it out with a couple of sharp taps. The bearing came off the tool easily with no visible damage. I repeated on the other side, and job done.I'll be having a go at the rear hub next.Thanks for a nice, easy to use tool.

Took a couple of attempts to understand how to use it (you have to do it up pretty tight), but worked flawlessly from then on. Took bearings out from a freehub body with just a couple of blows - far quicker than using a punch to work around the bearing.

Great tool, super quick delivery

Worked perfectly.
