PTC (Power Transfer Center) bottom bracket on our Citizen frame is made up of an 86.5mm wide shell, allowing the down-tube, chain-stay, and seat-tube to taper to the outer width of the shell and create undoubtedly the stiffest, most responsive bottom bracket concept to hit the BMX market. The head-tube of the Citizen is a taper 1-1/8" – 1.5" design which stiffens up the front end of the bike. The rear dropout of the Citizen is a 20mm design and the frame comes with 3 different axle compatibilities (10mm, 15mm or 20mm axle).
The Blackout PTC is the alloy version of our carbon frame. The Power Transfer Center (PTC) is what sets our Carbon and our Blackout PTC models apart from anything else on the market.
