    This is a follow-up to a thread that began on Dec. 24...I am answering my own questions now that the
    bike is finished.

    I found a SC Superlight frame at Phat Tire on the internet...The dealer in Charlotte didn't have one
    and had no hope of getting one for months. Phat Tire was the only vendor that I could find with a
    frame ready to ship.

    I started swapping some new parts and mostly old parts from my 99 Specialized Rockhopper to the
    Superlight.

    I had a new headset, a Cane Creek, S-2. I didn't realize that I was going to have to work so hard to
    get the headset cups and crown race on. I rigged a device with a threaded rod, washers, and bolts to
    press in the headset cups. I used a socket from a plumbing socket set to tap down the crown race.
    When I got it all together the headset was loose. I tried everything to adjust it right but it
    wouldn't work. I broke down and read the directions...(RTFM)...and found that a piece was missing, a
    split-plastic compression ring. I called JensonUSA and they promptly shipped one to me. When I
    installed it, bingo, the headset was OK. If I was going to do it over, I would ask Phat Tire to
    press in the headset cups, but it is done and it works. My Manitou SX fork worked fine along with my
    old stem and handlebars. The fit seems perfect after 4 rides.

    I had also ordered an XT front derailler...top pull to install, but it wouldn't fit. I called
    JensonUSA and he said that I ordered the wrong one. We arranged for a swap, and he shipped me the
    right one...top swing, top pull. When it arrived, it worked with no problem. This was another thing
    that I should have gotten from Phat Tire.

    I was concerned about threading the UN72 bottom bracket without having it first "chased." I was very
    careful and all went well.

    I had some problems figuring the cable routing. I screwed it up several times, but now it's right.
    I'm glad I had extra cables and other small parts. I couldn't get the rear derailler adjusted
    properly no matter what. I noticed that a cable jacket was too short and therefore to tight. It
    seemed to be pulling the cable whenever the suspension arm moved. I replaced it with a longer jacket
    and that fixed it.

    After 4 rides, I've noticed a couple of differences between my Rockhopper with a Thudbuster
    seatpost and the Superlight: When riding if I jump up and down on the pedals, the whole bike front
    and rear flexes. I didn't realize that even the weight on the pedals would be suspended...I thought
    just weight put on the seat would have shock absorption. The Thudbuster was good, but the full
    suspension is a worthwhile upgrade. The Superlight is noticeably lighter. I didn't think that I
    could feel the difference. It seems like the Superlight has better traction going up hill but I'm
    not sure. I like the Superlight, but the 99 Rockhopper was a good ride. I may have enough old parts
    to get it rolling again.

    In summary, the SC Superlight frame did come out of the box ready to go. The crown race and cups
    come with the headset. If I was going to do it over, I would buy the frame with headset cups and
    possibly the bottom bracket installed by a real bike mechanic.

    Well, you've found that these projects can often be more hassle than you bargained for. Actually,
    you may have been lucky.

    It's not uncommon to find a front derailer or BB that isn't exactly the right size, or that don't
    match each other -- and "professional" salespeople and mechanics who don't understand why. You can
    go back and forth with this several times, and through the mail this is a real PITA. Buyers of
    oversized seat tubes beware.

    IMO, the $20 or so that most shops charge to press a BB is well spent, unless you *know* you already
    have the necessary stuff on hand.

    The purpose of chasing the BB threads is usually to remove paint. Since the Superlight is not
    painted (either bare aluminum or anodized), there's no reason to have to do this.

    The Superlight is indeed a great bike. It's almost identical to a lot of other bikes, but Santa Cruz
    got it right and they didn't.
