1989 GT Avalanche
1989 GT Avalanche mountain bike features a Tange Prestige chromoly Triple Triangle frame with Shimano Deore II 21-speed HyperGlide drivetrain and SLR cantilever brakes.
Description
Only one avalanche can be ridden up one side of the mountain and down the other – the GT All-Terra Avalanche. Shimano Deore II componentry with 21-speed HyperGlide, high-performance BioPace chainrings, and SLR braking. Tioga Prestige II handlebars and Araya new RM-20 light alloy rims are assembled on the same frame as our Team model to create this aggressive off-road machine. The Avalanche is as exciting to look at as it is to ride, thanks to our custom Snow Storm and Arctic Storm three-phase paint finishes.
