BRAKE INCLUDED (no pictured)
The upgrades from the Neutron are a 100% Crmo frame, fork and bars, including the new fork with integrated cone shape design. Available in Cassette and Freecoaster versions like previous years, but this time, each bike has subtle details to give it a different look with the 2-piece bars on the Cassette version and the 4-piece bars on the Freecoaster version.
One new improvement that will make many people happy are the aftermarket Fuego tires and nylon hub guards that are included this year.
The Proton is our best selling model and we are stoked to make it the best Proton we’ve released yet!
The 2021 Proton is available in two colors; Savanna Dark Grey with Flat Black parts and Gloss Black with Polished parts.

Available in RHD or LHD. Specify your preference on "comments" when you place your order.
