OK Greg, now I'm going to have to post pics of my 63-speed mountain bike when I get home. It's a bit heavier than yours, doesn't have such nice brakes, and it's in commute trim right now... but WTF.

Eh 63 speed ! wow you'll be needing motorized changers for that thing...
and I thought a 24 speed was enough - duh what was I thinking.
Gregg - nice machine... $$$$!
Are you guys out racing or is this just for fun?
I took my 11year old out on thre mountain last weekend - he begged me - he came back all scraped up... his mother wasn't too happy - except that he loved it!
I promised him (and her) to teach him how to not fall off so much! Actually it brought back memories of my first year riding - way too many scrapes...
For me its purely for fun - and not often enough either - my riding partner injured his back about a year ago and I've go too many competing interests...

What's the cross bike in the background?

OK, here's some pics... it's basically a 21-speed older XTR grouppo mated to a Sachs 3-speed hub. I basically bought parts and made the bike I wanted. The frame was a compromise -- strong, somewhat light, and cheap.
The 3-speed can shift while pedaling with only the briefest letup of torque, and it can shift any time the wheel is turning without needing to pedal. 2nd gear is 1:1, 1st a .734 underdrive and 3rd a 1.362 overdrive. So my full range of ratios is from a .629:1 granny to a 5.221:1 overdrive. I could probably climb a brick wall in granny if I could get traction, and at 55 mph(local downhill) I can still pedal hard at a decent RPM.
So basically, I use the conventional gears to pick a range, then I can speed-shift, kind of like tiptronic. Or run a fairly low gear with the hub in high gear, then when I hit a technical section, I can just shift click-click without even pedaling and be in granny gear. It's an adjustment in style where you work it so you're using the hub to shift at times it would be inconvenient to use the derailleurs.
The right shifter is for the cluster, The left grip is for the hub, and the lever on the left is for the chainrings. I wanted a friction shifter here since this derailleur tends to need more fiddling to engage properly.
Anyway, here are some pics I took today. Yeah, it's a little dusty. Hopefully this year I can get more seat time than I have been getting.
