GT Team Roskelley 21"TT BMX Bike-Raw

The GT Team Roskelley 21"TT BMX Bike-Raw at J&R Bicycles features an upgraded spec with high-end components and performance without the high-end price tag. This intermediate level bike has been designed around GT’s after-market Team frame as an upgrade from entry-level bikes but is still beginner friendly. The steel frame and tapered fork are made from 100% Co-Mo tubing so they are built to last and take some tough landings. The 3-piece GT Power Series Cr-Mo cranks and GT 25T steel chainwheel help deliver balanced power and and a reliable ride. All the quality components you can expect from GT at a budget-friendly price point.

NOTE: As with any complete bike, J&R Bicycles recommends that you have a professional bicycle store build your bike. Bikes ordered through mail-order come partially assembled and need to be inspected and assembled by a bicycle mechanic. Failure to do so may void the manufacturer's warranty. Manufacturer's warranties differ for every brand. You can check the brand's website for warranty information.
