2009 GT GTR Series 4
2009 GT GTR Series 4 is an aluminium road bike built on hydroformed Kinesis 6061 butted tubing with a GT carbon fork and Shimano Sora 8-speed drivetrain.
Description
The 2009 GT GTR Series 4 is an aluminium road bike built around a compact frame design using hydroformed, smooth-welded Kinesis 6061 butted tubing — a construction method that balances stiffness and weight without resorting to carbon fiber at this price point. A GT-branded carbon fork with a 1-1/8″ threadless steerer keeps the front end responsive, while Shimano Sora rear derailleur and 8-speed STI shifters handle the drivetrain duties.
The FSA Vero Compact 50/39 crankset suits riders who want versatile gearing on mixed terrain, and 700c Alex R500 rims wrapped in Vittoria Zaffiro 700x23c tires complete a capable, accessible road package. Five frame sizes from XS to XL broaden its appeal.
