Description

Like the mountain in the Karakoram range it’s 94, the 1990 Karakoram came to stands above its peers. This radically improved competition bread bicycle features Tange MTB seamless tubing, Shimano Deore DX STI components with HyperGlide and OS steering system. The Karakoram K2’s aggressive disposition is enhanced by the GT 4130 chromoly seatpost, Shimano 2-finger brake levers, Ritchey Vantage rims and MegaBite tires. And with its Galactic Fade or Diamond Blue finish, this bike is as exciting to look at as it is to ride. Hit the road, and then head off it.
