    I finally got a chance to get an extensive test on the bike I built up this Winter. The cold snap
    finally broke and much of the snow melted on one of our local trails.

    The frame is a 17"er and I was a little worried that it would be cramped, but it ended up being very
    comfortable. I'm about 5'11" give or take a cent. here and there.

    Right off the bat I realized that I had the sag setup incorrectly, I should have had about 115 to
    120 PSI for my weight, which in full XC gear is at most 180. So the bob was a little more than I
    would have liked. Fixed that in a hurry and started down the lower half of the loop, which is easy
    to moderate. Most people around here take the upper trail first and then do the lower half on the
    return to the parking area to cool down and recover. I decided to do that first in case anything
    major happened because the bike wasn't fully tested after being built back around Xmas.

    I floated over everything on the trail, but I did notice that the BB height was a bit low, I smacked
    it a few times on outcropping rocks. I put an old school set of LX cranks on the frame, which are
    much stiffer than the ones on the giant HT. I was hooking up on everything and the roots for a
    change were a real pleasure to negotiate. There are a few rock gardens too and a stream crossing
    which the suspension handled with no problem.

    The Dakar uses a Fox Float R with 3.5 inches of travel and is actuated by a bell crank which
    hangs from the top tube. I had the rebound set too slow, three clicks from fast is all I needed
    for my weight.

    The bushings on the rear were a bit stiff at the beginning of the ride, probably because it was
    sitting on my deck (covered) all Winter. About 20 minutes into the ride they worked out though and
    became very smooth.

    I have a 2001 Z5 on the front which is a great fork. I leave it tuned to 80MM of travel because most
    of my riding is XC, that setting keeps things stiff and matches the rear shock well. It's a solid
    fork and smooth. Miles ahead of my old Judys' on the first hardtail I had.

    My Magura's are a bit of a problem though, I've been meaning to switch the brake fluid. Magura
    figured out about a year ago that they original fluid they used was too thick, it didn't return to
    the res. fast enough to prevent brake pump. The new fluid I've heard is a big improvement, and I'm
    also in need of new pads. I can't be certain but I think my LBS contaminated them the last time the
    system was bled.

    You can't tell much on the lower trail, but if anything was gonna fall off or break, I figured it
    would be easier to get back to the road if I had to walk back to the car.

    Once I got on the upper trail the bike showed it's stuff. Your either going up or down, and the
    single-track is off-camber for most of the distance. Making things more interesting is the roots
    which seem to get higher in number every year. I hooked up really nicely on those, and the steering
    was quick. The odd time I felt minor bobbing when I got out of the saddle to wank up a hill. I had
    to keep reminding myself to stay seated and spin. When I remembered to do that the bob disappeared
    and I got up the hills in much better shape than the old hardtail with much less wheelspin.

    Going down the hills was as simple as hanging off the back a little and staying low. The suspension
    did the rest without a hiccup. I was considering swapping the Float R for a lockout model, but
    changed my mind. Leaving the rear active was much more fun, and forces me to ride better instead of
    hopping out of the saddle every five minutes.

    The XT front and rear mechs perform flawlessly. I know for some guys/gals XTR is the sh*t, but for
    the cost and performance these suit me better for everyday riding.

    I had heard of some people experiencing a failure of the disc side chainstay. I contacted Jamis to
    enquire about it, and although my serial number didn't match the recalled batch, they sent me a new
    part anyway just in case. Even when I stupidly told the rep that I had bought the frame used, he
    didn't care. Sent me an original warranty as well. I'm deeply impressed with the level of
    professionalism these people have towards their business.

    Things I liked:

    -Stiff ride -minimal bob under heavy peddling -horst linkage -rebound on the rear shock -cables on
    top tube instead of underneath where it can get mucked up with mud

    Things I would Change:

    -Tires...my Mythos are getting long in the tooth, thinking about some Kenda's next -going carbon
    fiber for the seatpost and bars -lighter rims, I'm using some old Zac 2000's which are ok for discs
    but are heavy

    Be sure to let us know when you break it. Then again, weekend warriors don't put much wear and tear
    on bikes. Aww, you'll break it anyways.

    Already did hippie. Chainstay on the disc side, already replaced with the factory sub and working
    just fine.

    Let us know when you bathe and get a haircut/job okay? cheers

    I'm sorry but the typo in this paragraph had me laughing so hard I was in tears. Is it really a typo
    or is it a freudian slip?
