  1. I find that doing MUni is really sort of schizophrenic.

    First you ride up and down long hills for 40 minutes, or until you puke,
    whichever comes first. For this part, I need the seat very high,
    because I'm not strong enough to stand all the time, or to crank up
    hills sitting down low.

    Then you find some rocks and trees to hop on for 15-20 minutes. For
    this, I need to drop the seat quite a bit for optimal efficiency.

    Then you ride for 40 more minutes. Then more jumping, dropping, or
    whatever for 20 minutes. And on and on.

    I ride a KH24, and it has a pretty beefy seat adjustment mechanism, not
    much less significant then the vice I keep in the basement, what with
    the two hex screws and all.

    My question is, do many trail and trial riders use a quick release for
    the seat post? Are there good enough products? Are they trustworthy and
    safe for jumping and dropping? Crashing?

    It would certainly make the transitions easier if I could change the
    seat height without all the fanfare.

  2. The Salsa quick release is supposed to be excellent, and you can get it

  3. I just carry an allen wrench in my pack... I've got the Odyssey seat
    clamp: one bolt, plenty grippy, never had a problem! I do agree it is
    crucial to raise the seat for the longer climbs, but I couldn't imagine
    putting a quick release underneath me... who knows what it could snag?
    I don't want to find out :eek:

  4. I have always used a Salsa Fliplock quick release. I have no problem at
    all with the seat moving, and I can't imagine not having the convenience
    of being able to adjust the seat quickly, even if just for that person
    you meet on the trail that wants to give the uni a try.
    How well a quick release holds has a large amount to do with the quality
    of the QR, but also can be affected by the frame and seatpost
    compbination. I have an aluminum frame and Thomson seatpost, which I
    think is an easy combo to keep snug. A steel frame and chrome seatpost
    is probably the worst combination.
    I think you will have good luck with the Salsa. If you get one, keep a
    dab of grease or antisieze on the cam surfaces, and keep mud cleaned out
    of it. Operating it with grit in it can wear out the cams, and decrease
    it's holding power.

  5. I've always used a QR. I've got a cheap one and it works fine, never
    gone wrong.

    Double bolt clamps are obviously very reliable and tight, but it's just
    so much hassle to let people have a go on the uni. Also I sometimes swap
    posts between unis and having a QR is really handy.

  6. I've never used anything but quick-releases from Bedford on my commuter
    and street/trials unis, and i can't complain about them. Sometimes when
    you bail and the handle of the saddle hits the ground, the saddle gets
    twisted to the side, but straightening it takes 2 seconds.

  7. I have a double hex thing on my trials unicycle, i'm not sure if I would
    trust a flip release one when jumping for tall heights. I used to have
    one when I was learning (on a skinny freestyle uni) and that got
    twisted and stuff now and again.. so I'm afraid to try the fliplock
    thing (plus it's about £14 / $24 + delivery).

  8. i currently have a quick release and although its easy to use, i
    absolutely hate it. but that is pretty much because of the kind of
    quick release it is.
    http://www.unicycle.com/shopping/shopexd.asp?id=249, its simmilar to
    that one, except it will fit on any unicycle. dont buy anything with
    that kind of arm thing, because its extremely dangerous. i was riding
    one footed for a while then that arm caught in my shoe and i fell. when
    it came down the arm hit me right in the back of the heal stabbing me
    nearly in the achilles tendon.

    so beware quick release arms.

  9. Hey this was what I was looking for also! Thanks guys for the info. I
    will go buy a quick release since I am tired of bringing a wrench with
    me all the time. :P

  10. i saw many people at muni weekend withe the salsa clamps, the only bad
    part about them i think is that they stick out a bit and can get caught
    on u.

    i agree with maestro8, just carry an allen wrench

  11. The 'Salsa' (http://www.salsacycles.com/comps_skewers.html) Flip-Lock
    (the quick release seatpost collar) is the only quick release I've used
    that clamps tight enough for muni use. I use it with a Thomson
    seatpost and it hardly ever twists or slips. The arm does stick out
    but I've never had a problem with it hitting me during a UPD. It works
    well and is solid. It's a bit spendy but worth it.

    There are single bolt seatpost collars that clamp tight. The Salsa
    Lip-Lock works well. Clamps as tightly as the Flip-Lock. If the arm
    sticking out of the Flip-Lock scares you then you can get a quality
    single bolt collar.

    'Surly' (http://www.surlybikes.com/parts.html) makes one called the
    Constrictor.

    There are some other beefy single bolt collars as well.

    Take your uni to a bike shop and have them measure the OD of the seat
    tube so you know what size of collar to get. Or if you have a caliper
    or micrometer you can measure it yourself.

    The trick with the single bolt collars is to grease or anti-seize the
    threads of the bolt. That will allow you to get it tighter without
    damaging the threads. Tighter means less slipping. Same with the
    Flip-Lock. It needs grease or anti-seize too on the threads and on the
    cam surface. A little grease between the frame and the collar is also
    a good thing.
