  1. The other day I bent my rim on my 26 Sun. I would strongly advise
    against doing jumps on a Sun because they are not very sturdy. Looks
    like I have to go down to the bike shop now, unless someone knows how to
    fix a bent rim in an easy manner.

  2. unless the bend is VERY slight you will need to take all the spokes out
    & bend the rim back straight, then rebuild the wheel. It is quite
    trickey to bend rims straight & they will never be as good as a new one.

  3. iamthewaltrus, i might be able to help. PM me if you're interested.

    By the way, do you know about the 'Austin One Wheelers email list'
    (http://place.org/cgi-bin/mailman/listinfo/aow)? If you're interested
    in joining us for rides, you should join the list.

    Also, we have 6-12 unicyclists showing up at the 'weekly TJS juggling
    meetings' (http://www.juggling.place.org/regularmeetings.html) now,
    consider joining us some thursday evening.

    Nice job! Even with no kinks that rim was a mess. Most bike shops
    wouldn't even attempt to straighten it. How did you get it back without
    introducing a few kinks?

    It has a few kinks still.. it is sort of experimental..
    Once it has been ridden on I may have more comments :-)

    I used a straight edge to try and judge how I wa doing with it & took my
    time (probably spent getting on for 2 hours just straightening it).

    The rim is so soft you may be able to get more life out of it by
    simply truing the wheel. Most good bike shops should be able to help,
    though mechanics used to doing precision work could get confused
    trying to put the wheel on a truing stand. Tell them to get it as
    close as they can and it should be fine.

    If the rim is beyond repair, I'd recommend looking at a new wheelset
    rather than a rebuild. The Sun hub is a piece of junk - mine sheared
    off at the hub and I wasn't even hopping on it. The Semcycle XL
    wheelset from Unicycle.com might be a good choice, though
    single-walled rims aren't the strongest. The bad news is that it
    costs as much as a new Sun unicycle ($80).

    OOps! Make that: Mine sheared off at the stud for the crank nut.
