This was the xc race version of the i-drive with shorter chainstays, longer top tube, and (I guess) lighter frame wt.....offered first in 2001, but now offered on sale at Greenfish Adventure Sports for $550 for frame and Manitou QR shock, and various other options with Manitou forks/Cane Creek headsets. Site states frames made in 2004 at Kinesis USA (?Oregon). Don't know about warranty or replacement parts issues, but it looks like could be built up into a race-worthy vehicle. To make this more of an exercise, would ask GT affectionados to come on board and spec out a build that would come in under, lets say, $1800- $2400 maximum. (one build on the site listed is $1999). How would you build up this bike for racing and trail riding with todays parts?
