Twitter G2max-PB
The flat-bar sibling of the G2max, the Twitter G2max-PB keeps the same tough aluminum-alloy gravel frame and carbon disc fork but swaps the drop bar for an upright alloy flat handlebar — an approachable, do-it-all machine for commuting, fitness and light off-road. Wide 700×50C tires and full-hydraulic disc braking handle any surface, with a choice of Shimano CUES 1×9, LTWOO 1×12, or LTWOO 2×12 drivetrains.
Key Features
- ▪ Lightweight Aluminum-Alloy Frame (Disc & Thru-Axle 12×142) with carbon disc fork and internal cable routing.
- ▪ Upright Flat-Bar Cockpit — confident, comfortable control for city and trail.
- ▪ Three Drivetrain Builds — Shimano CUES 1×9, LTWOO 1×12, or LTWOO 2×12.
- ▪ Full Hydraulic Disc Brakes (160/160mm) for confident all-weather stopping.
- ▪ RS AL7005 Alloy Wheelset with wide INNOVA 700×50C tires for monster-gravel grip.
- ▪ Threaded Bottom Bracket & Sealed Bearings throughout for low-maintenance durability.
