Don't get me wrong, I love the bike, but I could do without the adjustable geometry on this thing. I decided to put my bike into full freeride mode (moving the shock forward, dropping the rear end) as I'm doing a lot of Big Bear riding. I knew it dropped the BB height, and figured it'd drop it about .3" given that it was previously in the halfway position and the adjustment range was between 12.9-13.5" of BB height. What I didn't realize was how precious that .3" is.
I adjusted it Thursday night, then went out for some urban riding around UC Irvine (mostly just broncoing stuff) and had a great time. No problems, took a little getting used to the different geometry, as one would expect. Then on Friday eve. went to Whiting Ranch (a local six mile definition-of-average-trail) and had no problems on the climb. The fast fire road descent went okay.
And then I hit the single track...and everything changed. Pedaling through a fairly flat section the right crank impacted the ground on a baby-head sized rock. According to the rider behind me, there was an explosion of sparks (thank goodness ATACs are stout). No damage other than a highly scratched pedal. Thought "okay, it's a little lower, watch out for that". Continued along. Slight right turn, pedaling, accelerating, hit the ground (not even a rock, just rocky ground with a 1" deep texture, tops). bike pivoted to the right, slammed ankle into crank so hard I thought I'd broken it, but just badly bruised. At this point I thought "gee, this thing is really LOW, I really oughta just take it easy until I get home". Final turn. Mellow. Pedaling in corner with very slight lean. Touchdown, left side on smooth flat dirt. Bike goes into left hand drift and I wind up sliding about ten feet to a stop sitting on top of the fallen bike like it was a toboggan.
Needless to say, I think the adjustable geometry sucks , at least if you want to go toward an FR style geom. Did like the slacker head angle though. Measured the BB height and it was 12 1/2" (to the center). CDale claims 12.9" At the midpoint of the geo adjustment it sits at 13 1/8", so I was running it 5/8" lower. I set the shock at the farthest forward position possible, with one whole thread remaining (i.e., I could stick a fingernail between the last thread and the shock).
Just figured I'd post this as a warning and to see if anyone else had a similar experience. The Jekyll's a great bike, but I think I'll leave the geometry alone from now on.
