1990 GT Timberline
1990 GT Timberline mountain bike features a chromoly Triple Triangle frame with internal cable routing, Shimano 500LX STI RapidFire shifters, and a 21-speed HyperGlide drivetrain.
Description
The Timberline’s triple triangle frame with seatstay mounted U-brake and internal cable routing sports a sleek, new look. It offers a low maintenance wheel combination of Araya alloy rims, Shimano alloy QR hubs with rear cassette, and stainless steel spokes. With Shimano’s new 500 LX STI RapidFire shifters and 21 speed HyperGlide system, changing gears has never been easier.
A comfortable ride is assured by the natural handlebar position and anatomical GT/A’ME grips. The soft GT GELCEL saddle will be appreciated at the days end. In rock like Granite or Gloss Red, the Timberline is not just a ride… It’s an adventure.
