REI (2009)

Thanks to the low-maintenance Gates Belt Drive, internal 3-speed gearing, fenders, rear rack and panniers, the GT Aerostream is, without question, an urban do-it-all bike.
- Lightweight, hydroformed aluminum frame features beautiful, sloping lines and easy-riding geometry for supreme comfort, be it commuting, errand-running or simply joyriding
- Gates Belt Drive drivetrain uses a belt instead of a chain—this system is exceptionally long lasting, virtually maintenance free and nearly silent
- Belt Drive system doesn't require lubrication, meaning no greasy chain to deal with; just in case, the full-lengh chainguard prevents clothing from getting caught in drive
- Shimano Nexus 3-speed internally geared rear hub features 3 handy gears for getting around town; shifting is a breeze with a simple turn of the twist shifter
- Tektro linear-pull brakes provide easy management of speed; fast-rolling 700c wheels are outfitted with tough hybrid tires to keep you rolling smoothly around town
- Fenders, rear rack and panniers are included, just in case the deal wasn't already good enough
- Specs are subject to change
