GT Bump 2013 BMX Grey

GT Bump 2013 BMX
Now $389 RRP $489

The GT Bump has a cro-moly frame, and is a mid-level bike in the GT dirt/street line of BMXs. This is a BMX designed to keep its feel, no matter what terrain. The dirt/street handlebars that come stock on the GT Bump are Pro size, to give good control. The GT Sandbox Dirt Tread tyres help in this cause, as they are made to withstand rough tracks.

The wheels have a 14mm axle at the rear with 36 spokes, and the front wheel is lighter with 3/8" axle and 32 spokes. The hubs are GT with Alienation PBR rims.

So the wheels are pretty tough. The GT Bump also comes equipped with pedals and cranks designed for jumping. The cranks have 8 splined cro moly axles with mid-size bearings. The pedals are GT dirt/street design, made of alloy with cro moly axles which are designed to perform safely under tough conditions.
