  1. I would like to know if a KH trials unicycle can be retro-fitted with a
    Profile hub. The bearing sizes are a little different. The Profile's OD
    is 1-5/8" which is 41.275mm and the KH frames are designed to accept
    42mm OD bearings. I remember some time ago there were shims (from
    unicycle.uk.com, I think) around to fix this issue. In the absence of
    these shims what other solutions are there? I guess I could try the old
    Coke can shim, or maybe stacking some washers between the bearing holder
    cups to give them something to clamp against.... Any ideas?

    Jagur posted that he has done this upgrade and didn't need to use shims
    at all. I wonder how well the bearings on that unicycle are holding
    out.

  2. I think you can just get bearings for the Profile hub that will fit both
    the inside diameter of the hub and the outside diameter of the bearing
    holders. Maybe you could email Gary of unicycles.com.au about it
    because I think he has put plenty of Profile hubs in 42mm bearing
    holders.

    the Profile size bearings work fine with the KH frames. there is not
    need to use the shims with the Profile sized bearings.

  4. I run a KH Pro Trials frame with Profiles...but that design is quite a
    bit more than the standard frame (well worth the price though) and is
    only really necessary if you are snapping the standard version...But
    there is that option, depending own how strong a unicycle you want. I
    like mine bomb-proof!

    Sorry to bust your bubble, but the only real difference between the KH
    pro frame and the normal one is the pro is $400 more, has 40mm bearing
    holders, is hand built in Canada, and it may have brake bosses. The only
    reason they are $400 more is that Kris had to ask a welder in Canada to
    custom make a small batch of them. They aren't really any stronger.

    Zack Baldwin and Ryan Atkins both run KH normal frames on profile hubs,
    as of the last muni weekend.

    My KH Pro frame has 1-5/8" bearing holders. It was the first batch of
    frames made. After that they switched to the 40mm size.

    The only practical difference between the KH Pro and the KH Taiwan are
    cosmetic. The bearing holders on the KH Pro are nicer than the bearing
    holders on the KH Taiwan. There are other cosmetic differences too like
    smoother welds. Plus there is the warm feeling you get from buying
    something manufactured in Canada. The cost difference is because
    Canadian labor is more expensive than Taiwanese labor and the KH Pro
    frame is more carefully made.

    When the 2004 KH Taiwan frames sell out, the remaining KH Pro frames
    will be an alternative for the people who don't want the new aluminum KH
    frame. I'm betting that Unicycle.com hasn't sold many (if any) of the
    KH Pro frames since the KH Taiwan frame was available. Maybe now the KH
    Pro frame sales will pick up as an option for those who don't want an
    aluminum frame.

  7. OK, so you can fit a Profile hub in a KH frame. I've had confirmation of
    this from unicycles.com.au - thanks for your suggestion, Andrew.

    One thing I can't understand is why the KH20 Pro model has brake mounts.
    Why on earth would you want brakes on a trials unicycle? Maybe if it
    were used as a kids' mountain uni, I could understand it, but the KH20
    Pro wouldn't be your first choice for a kids' Muni due to its relatively
    high price....
