Bent my rim

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.

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.

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).

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.

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

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).
