1989 GT Karakoram
1989 GT Karakoram mountain bike features a triple-butted Tange chromoly Triple Triangle frame, Shimano Mountain LX 21-speed HyperGlide, and SLR cantilever braking.
Description
The Karakoram’s competition series Triple Triangle Design™ frame is constructed of triple-butted Tange MTB tubing. Its full chromoly fork features tapered 1 1/8-inch blades and forged dropouts. ‘Dialed in’ was how Mountain Bike Action and Bicycling magazine described the Karakoram’s aggressive geometry. The rugged nature of the Karakoram is made evident by Shimano’s Mountain LX group with 21 speed HyperGlide, high-performance BioPace chainrings, and SLR braking. Grey anodized Araya RX-7 alloy rims, stainless steel spokes, and sealed mechanism hubs provide long life with less maintenance. GT All-Terra toe clips and straps, a Flite GelCel™ saddle, and two custom paint finishes – Granite or high-gloss red – round out the impressive package the Karakoram presents for eager off-road enthusiasts.
