Twitter GTR Dirt Jump
Built to take a beating and ask for more, the Twitter GTR is a Dirt Jump-grade hardtail engineered for hard landings, pump tracks, and aggressive trail riding. Its smooth-weld AL6069 aluminum frame runs a stout Thru-Axle 12×142mm Boost rear end, while a 150mm-travel TW air suspension fork on a 15×110mm Boost axle soaks up the biggest hits. A wide-range 1×12 SHIMANO DEORE M6100 drivetrain and SHIMANO MT200 hydraulic disc brakes keep power and control on tap, lap after lap.

Engineering & Design Highlights
Suspension Fork
A TW magnesium-aluminum air suspension fork delivers 150mm of plush, tunable travel with manual control. Mounted on a stiff 15×110mm Boost thru-axle, it tracks straight and stays composed through rough landings, drops, and choppy trail chatter.
Trail Drivetrain
A SHIMANO DEORE M6100 1×12-speed drivetrain runs a SENICX hollow 36T crankset into a wide-range SUNSHINE 11-50T cassette and SUMC chain. Clean, reliable shifts and a huge gear spread cover everything from steep climbs to fast pump-track exits.
Hydraulic Disc Braking
SHIMANO MT200 hydraulic disc brakes clamp 160mm front and rear rotors for powerful, modulated stopping that holds up in mud, dust, and heat. Confident one-finger control means you can brake later and ride harder.
Drivetrain Configurations
SHIMANO DEORE M6100 — 1×12-Speed
SHIMANO DEORE M6100 shifter and 12-speed rear derailleur drive a SENICX-FM3 hollow 36T crankset into a SUNSHINE 11-50T cassette with SUMC 12-speed chain. A clutched, wide-range setup built for dirt-jump abuse and trail versatility.
RS LTWOO AT — 1×13-Speed
Alternate configuration running an RS LTWOO AT 13-speed groupset for an even broader gear spread. Same Dirt Jump frame, fork, and SHIMANO MT200 hydraulic disc braking — just an extra cog of climbing and descending range.
