The Lightest 2018 Aluminium Race Frame BMX in NZ

The Speed Series is the New Season 2018 Race BMX range from GT, featuring light and fast alloy frames in a gloss neon yellow.

We currently have the full range of sizes available: Mini Race BMX; Junior Race BMX; Expert Race BMX (recommended for riders between 1.5 - 1.65 metres); and Expert XL (for riders between 1.6 - 1.7 m). 

The Expert XL shop floor stock is currently on display with steel forks, with option to upgrade to BOX “XL” Pro Carbon Forks. 

Sticking with the steel forks is an economical way to get a great BMX this season. Options to upgrade forks to carbon at a later date.
