I LOVE my mountain bike - it was just about the only thing I brought with me when I moved to Panama a year ago. Currently ripping some trails here in the tropics, but damn the humidity is killer! Hopefully when I get back to the UK I will be a XC machine!
I was lucky enough to be able to buy my dream bike a couple of years ago, spec as follows:
Pace RC 300 Alu/Carbon Fibre frame
Pace RC31 rigid Carbon forks
Pace RC 46 CNC stem
Chris King headset
Hope XC Alu/Titanium hubs with Mavic 317 disc only rims
Hope Titanium quick releases
Hope XC4 four pot hydraulic discs front and rear
Middleburn Crankset and Hardcote teflon coated chainrings
Raceface Titanium bottom bracket
XTR front and rear mechs
XTR shifters
XTR clipless pedals
X-lite Carbon riser bars
Thomson Elite seatpost
Flite Ti saddle
Panaracer fire XCPro 1.8" tyres
It weighs about 19 pounds in current trim, and climbs like a mountain goat! Just don't even ask how much it cost....
Here are some links if you guys outside the UK have not heard
