  1. [If you don't care about my muni plans, or don't want to read too much,
    continue to the questions below]

    I finally have a bit of money set aside to spend on my muni which is
    good because it's really not running very well.

    CURRENT MUNI
    * Old GP Unicycles prototype frame
    * Profile hub and 145mm cranks
    * Kona Jackshit pedals
    * Alex DX-32 rim
    * 24x3" Gazz
    * Magura HS-33 brake
    * KH seat

    PROBLEMS
    * Frame - nice, but too heavy and not enough clearance either side of a
    Gazz...and not custom.
    * Cranks - 145mm is far too short for the type of riding I'm getting
    into.
    * Pedals - Spindles always bend eventually, and bearings are playing
    up.
    * Rim - Had to be dished to one side to fit in the frame, is also
    generally getting old, is too weak.
    * Tyre - Beautiful, but getting worn and is also heavy, and it doesn't
    sit in it's bead right.
    * Brake - I don't have the proper Magura bosses that attach in two
    places, crossover cable is too short.
    * Seat - starting to rip through base plate.

    FUTURE MUNI
    * Custom frame - Very similar to my fisrt custom frame (now owned by a
    friend) but with minimum of 10mm (probably more) clearance either side
    of a 3" Gazz, no extra grippy bits of one footed skills, approximately
    250mm long neck to put the seatpost clamp right up high. It will run a
    22.2mm seatpost because I have a bar end to mount the brake lever on for
    that size and the neck will be long so no worries about strength.
    Tubing will be ovalised at about 30x10mm, bearing holders will be
    machined. Proper Magura brake bosses will be welded on. -Colour will
    be a powder-coated white!-
    * 160mm Profile cranks - I've ridden 152's on a really light 24" muni
    wheel and it felt great, so 160mm on a chunky 24" wheel should be
    perfect for me. I will still have a bit of clearance above all the
    ruts, roots, and rocks of Mt Cootha.
    * Really strong pedals - I'm thinking Odyssey Jim Cielencki's because
    they sound strong and reliable and that beautiful blue colour would go
    great with either a white or nice orange (second preferance) frame. Any
    thoughts? I also looked at DMR V12's and rode with some yesterday.
    They feel nice and are apparently strong.
    * KH Freeride rim - I love the sound of that lateral bracing of a
    muni-specific rim! Slightly heavier than a DX-32 but well worth it I'm
    hoping and I'm possibly running a lighter tyre.
    * 24x3" Duro - This is what I'm considering anyway. I love my Gazz, but
    I also love a light wheel, and this is apparently noticably lighter.
    * Proper Magura brake bosses, and braided hydraulic cable not just for
    the cross-over cable but all of it.
    * KH seat - It hasn't broken yet, and it's very comfortable...although I
    was considering getting the GB4 stiffened Miyata.

    QUESTIONS
    * If I want to change the colour of my frame at some stage is it easy
    and cheap to remove the existing coat of paint?
    * How does the 24x3" Duro perform in terms of folding on drops and also
    hopping on off-camber surfaces?
    * Which pedal (Jim Cielencki, V12, Snafu) has the strongest spindle?
    Any others? (the pedals always go first on my unis)
    * Anyone have any pics of white muni frames? I'd like to see roughly
    how it will turn out. Otherwise, I may go for a nice orange.

    Thanks a lot,
    Andrew

  2. I'm chuckling to myself seeing no responses! I think you know as much
    if not more than anybody here......

    Save up even more money (better yet show some potential sponsor your
    video footage, it's spectacular), and get all the variations you
    mentioned and do an open study for the unicycling world to
    see.........we'd all benefit, and you'd have one heck of a fun time.

    Sincerely,

    Bob

    * If I want to change the colour of my frame at some stage is it easy

    Removing paint from metal is quite easy, especially with a sand blaster.
    For a blasting medium, stay away from the aluminum oxide, go for either
    sand, walnut shell, or glass bead. Glass bead is the best if you can
    get it. If you don't have access to one, try an electric or pnumatic
    orbital sander. The sand paper should be a medium grit. You could even
    try a chemical stripper, but I don't like those.

    Removing powdercoat is quite a bit harder, as it adheres better to metal
    and is tougher. I've never tried removing it with anything but a sand
    blaster. It is really tough even with a sand blaster. For example, I
    once sandblasted an onza frame, which came powdercoated matte black, to
    be powdercoated again. It took a good hour or so to sandblast the
    entire frame to bare metal. This was surprising, as when I sand blasted
    a chromed frame to bare metal (it was a Yuni frame), it only took a
    little more than 15 or 20 minutes. The finished products can be seen
    'here (onza)' (http://gallery.unicyclist.com/album346/DSCF0002) and
    'here (yuni)' (http://tinyurl.com/42aje)

  5. Ive tried duros several times on varying terrain. I still like my gazz a
    whole lot more. The gazz feelings springier on hops, more cushioning on
    drops, and -you guessed it- better grip on off camber surfaces.

    I would prefer to skimp in the paint department and put that money
    towards a gazz if need be.

    Maybe someone has ridden alot on both and could give us a more
    experienced opinion.

    That looks like a killer muni you're cooking up. Good luck and enjoy the
    process. 😄

  6. Also, if you do end up powdercoating it, I wouldn't go for white. The
    reason is that it looks nice for a few weeks, but then it gets very
    dirty and scratches are very noticeable in it. Plus you'll get black
    rubber marks in it from your shoes during UPDs. At least that is what
    has happened to the ghost.

    Then again, it is a muni, so it would look good dirty. :p

    Yes, but I dug around and nothing's scanned. In 1985 you could order
    your first-year Semcycle in either chrome or white baked enamel. The
    white ones were sweet, because it was such an unusual color.

    As somebody else mentioned, white will look really cool for starters,
    but it will show all the dirt, scratches, scuffs, rust very vividly.
    While the dirt and scuffs can be washed off, you're stuck with the
    scratches, chips, dings until you refinish it.

    But that's okay. The thing is made to be used, right?

    Back to the Semcycles. I think the white option was only around for the
    first year. Same problem, once they got scratched up, which is
    inevitable for any frame, they looked worse than the equivalent amount
    of wear & tear on a chrome frame. I don't know how durable baked enamel
    is compared to powdercoat, but in terms of being scratched it probably
    doesn't matter much. The problem is contrast of colors.

    So though it hasn't worked for a production unicycle, no reason you
    can't do it and stand out with your custom one.

    Cheap Snafu`s ($30) are lighter than JC pedals and plenty durable.

    I agree. I have ridden the Gazz and the Duro quite a bit. When my


    current Gazz wears out, I will go to the Duro. It is a subjective thing:
    I like how the duro responds better and the Gazz seems to have some
    unique problem in wet terrain. Moreover, I feel comfortable riding a $20
    tire over pavement (I like mixed riding) rather than a $60-$70 one. I
    can wear out a tire every month (or more).

    was considering getting the GB4 stiffened Miyata.

    I am in love with my GB4 stiffened Torker frame (I do not think the


    Miyata is available - at least it wasn`t when I was buying). It`s cheap,
    modular and has flawless performance. I currently run it as a airseat,
    but it can work with KH foam as well.

    * How does the 24x3" Duro perform in terms of folding on drops and also
    hopping on off-camber surfaces?

    Quoted message said:
    Quoted message said:
    Quoted message said:

    I think the Duro feels better laterally (even though the Gazz has


    the sidewall thing goin` on). It also feels better with higher pressure.
    At very low pressure the Gazz works out better. I`d rather have a Gazz
    for serious drops and extremely rough (dry) terrain. I would rather have
    a Duro for everything else. The Duro also seems to benefit more from
    changing air pressure. (Simply lower the pressure for rough terrain and
    drops to get a more Gazz-like feel). The Gazz is clearly more cushy, but
    the Duro responds more quickly (which is what I like - dealing with an
    obsticle at the time I reach it rather than a 1/2 second later).

  10. Bob,
    Wouldn't it be fun to be rich!

    Smilymarco,
    Thanks, exactly what I was looking for.

    digitalattrition,
    Thanks, I was actually thinking that dirt, mud, and scratches on white
    would look great. I'm not one of those people who like to keep a muni
    spotless...I like it spotful. 🙂

    mango,
    I will keep everyone informed about the progress. You know me...I post
    about everything that goes on in my unicycling life here! 😉

    John,
    Thanks for the interesting info, and see above about the scratches,
    etc.

    Drew,
    I'm going for a custom frame not to save money or anything but because I
    like having a frame the nobody else has. I'll look into those Snafu's a
    little more now, thanks. I believe Tony Melton runs Snafus on his
    trials uni which I have ridden and they felt great and looked solid and
    reliable. I currently have an Alex rim, but I'd like something stronger
    and I'm also just really excited about this KH Freeride rim. I meant to
    say I was considering getting the old GB4 stiffened Miyata seat out,
    meaning I have one sitting here at home with the dreaded spinning bolt
    problem and don't have the tools to fix it so I'll have to take it to a
    friend's house and get it running again. That's interesting about the
    Duro's responsiveness. Here in Brisbane, Australia the trails are very
    dry with heaps of ruts, rocks, and roots. I think the responsiveness
    you mention would come in very handy down some of the steep rocky
    decsents I've come across. I'm also doing all of my bigger drops (above
    5'😉 on the trials uni, so I think the Duro might be the go. As you
    said, it's only a cheap tyre so it's not a huge drama if it doesn't
    suit. The little bit of money wasted (if it is wasted) would just blend
    into all the money I'm spending on this fancy new setup. 🙂

    Thanks for your help guys.

    Andrew

  11. Ask Joey Cohn for a pic of his uni after cmw 04 to get an idea of what
    you will have. He had a yuni frame with bosses powdercoated white before
    the weekend. It was beautiful, but the powdercoating on the outside tops
    of the legs had disappeared in the 3 days of riding.

    If you'd like to know, I have cracked the back half of my left snafu
    pedal. I think it was on the flight to NYC, since I read that it was -71
    F outside, and if the luggage bay wasn't heated the thermal contraction
    of the metal may have caused it to crack. I would go with the jim c's
    myself, or the azonic a-frames. Not wellgos.

    the KH rim doesnt appear to have a machiened side wall either.

  14. For months now I've been hearing people talk about the KH Fusion saddle
    and never looked into it, assuming it wouldn't be all that different to
    my existing KH saddle. I just had a browse through www.krisholm.com and
    I now want one! I love the removable cover and more durable baseplate
    and cover material. Are they heavier than the 2003 KH saddles?

    Which leads to my next thought...the Fusion saddle is completely black.
    I am also now considering a few more colour combinations including
    completely black.

    ...this is going to be soo expensive!

  15. powder coating is almost impossible to strip off and change color, not
    to mention expensive, white shows, blah blah its been covered.

    I really like the snafu pedals. I also love my gazz. i only have the 2.6
    and for everything but the biggest drops/bumps and the muddiest
    conditions if works well. Might be something to look into. for a saddle
    i really like my air seat with a GB4 seatpost and reeder handle. Haven't
    even see (in person) the new KH saddles, so i can't comment. all i can
    say is you'd better have tons of pics when you get with this.

    WARNING! When blasting with sand yourself, don't inhale the dust. In
    the Netherlands, professional sandblasting has to be done in a fully
    closed cabinet (with "inverted gloves" to handle stuff) with air
    suction. Sand dust in your lungs is known to cause silicose, which is
    a serious and potentially fatal condition.

  18. Pedals:

    Consider the '2005 Specialized Lo Pro Magnesium pedals'
    (http://tinyurl.com/5wquk) if you can get them in Australia for a
    reasonable price. They are a bit spendy at around $83 here in the USA.
    They're supposed to be really good pedals with a strong spindle. I
    haven't tried them yet.

    Or if you want something cheaper go with the Jim Cielencki's with long
    pins. You don't want pedals that you can't afford to abuse.

    Seatpost:

    If you use a 22.2 mm seatpost you will need to custom make one that is
    stronger than the standard seatposts. Otherwise it will end up looking
    like daino149's avatar. The weld area is vulnerable on that style of
    seatpost and will need to be beefed up.

    22.2 mm seatposts are also harder to keep from slipping in the frame.
    The smaller diameter means there is less surface area to clamp. A
    larger diameter seatpost will have more surface area and can clamp
    tighter as long as you use a good seatpost clamp and the seatpost fits
    properly in the frame.

    A standard bicycle seatpost size like 25.4 mm or 27.2 mm will allow you
    to use a high quality alloy bike seatpost (Thomson) along with a rail
    adapter to set the seat angle. It works well as long as the rail
    adapter is built strong enough to take the abuse. Weak welds on the
    rail adapter can crack.

    Brake lever mount:

    Consider using the style of brake lever mount that municycle.com has:
    'Brake lever mount for KH saddles' (http://tinyurl.com/4xhqt). No need
    to attach a bar end to the seatpost. Scott Wallis also uses a similar
    brake lever mount for his ultra-custom seats: 'Scott Wallis handle and
    brake lever mount' (http://www.wallisdesign.com/HANDLEpics.html). I can
    see a lot of advantages for that style of brake lever mount compared to
    the other options.

  19. Pedals:

    Consider the '2005 Specialized Lo Pro Magnesium pedals'
    (http://tinyurl.com/5wquk) if you can get them in Australia for a
    reasonable price. They are a bit spendy at around $83 here in the USA.
    They're supposed to be really good pedals with a strong spindle. I
    haven't tried them yet.

    Or if you want something cheaper go with the Jim Cielencki's with long
    pins. You don't want pedals that you can't afford to abuse.

  20. Mark,
    Don't worry, I'll take heaps of photos! It's going to be absolutely
    beautiful.

    PopeSamXVI,
    Well I just picked up some free machined bearing holders, so the rest of
    the frame will cost about $230. Last frame I designed and had made cost
    $232 without the bearing holders. Quite reasonable really. I just
    tallied up how much this baby is going to cost me and I'm looking at
    about $800 with discounts and mate's rates...WOW!
