The Proton has been refined for 2019 just like the rest of the Fly mid-range bike line, The fork has been upgraded to a hydroformed 1-piece steerer tube. This bike now comes with a Trebol headset, a stronger 510 chain, bigger bars and a taller standover height, improving the overall look and feel, The cranks have been upgraded to the clean Trebol Bueno cranks. The 2019 Proton now comes equipped with four pegs, a shorter 13” rear end and shorter 28mm offset forks that is geared more toward the street riders out there!
