1989 GT Karakoram K2
1989 GT Karakoram K2 is a chromoly mountain bike featuring double-butted Tange MTB tubing, SunTour XC-9000 derailleurs, and a 21-speed drivetrain.
Description
K2 is the tallest peak in the Himalaya’s Karakoram mountain range. What better name exists for the newest version of our most celebrated bike? The Karakoram K2’s competition series frame benefits from double-butted Tange MTB tubing. Its responsive mountain bike geometry answers your every command. SunTour’s all-new XC-9000 and 9010 derailleurs with AccuShift and a seven-speed cassette freewheel provide 21 earth-churning gears. SR’s best FX cold-forged crankarms with oval inner chainrings and round outer chainring transfer all pedaling forces into fast-forward acceleration. DiaCompe’s new two-finger Advantage II brake levers with 984 front cantilevers and 994 rear U-brake put a stop to the high-speed excitement. In either shocking Violet Thunder or purely professional Pearl Grey, the Karakoram K2 will conquer you in a single glance.
