Overview
About this bike
The Astron is our fully-fledged skatepark machine with a visual appearance that will leave the competition in envy. In addition to the lower standover and responsive park-inspired geometry, the Astron is kitted out with a Salt gyro setup and lighter Saltplus 2.30" Burn tires, making it the weapon of choice for the technical park rider who wants a bike with an unmatched parts list and a paint finish that can't be found anywhere else.
