Tackle your urban commute
Shimano SL-TX30 7S Thumb Shifter Plus is equipped to handle hills, trails, and city streets with ease. With that multi-speed drivetrain, you can get up hills and trails better and faster with less exertion and exhaustion.

Keeps dirt and grime out
What is a "sealed cartridge bearing hub", you ask? Only the best thing since sliced bread (although, bread is pretty great). Sealed cartridge bearing hubs are a game-changer for any city rider. This feature protects delicate parts of your bike from damage that can be caused by gunk in the road. They also require less maintenance compared to their loose bearing counterparts.

An impressively smooth ride
Front and rear aluminum alloy brakes give you more control and more robust stopping power. 700 x 32c all-season tires lay a perfect foundation for an impressively smooth ride, even on slick or uneven roads. This is the ultimate commuting machine.
