Twitter Stealth Pro 2rd
Engineered to slice through the wind and hold speed on every road, the Twitter Stealth Pro 2rd is a full high-modulus carbon aero road machine. Its STEALTHpro monocoque frame and fork, fully integrated carbon cockpit, and internally routed cabling create a clean, drag-cutting silhouette. A modern 1×13-speed drivetrain — offered with race-proven mechanical or wireless electronic shifting — pairs an 11–46T wide-range cassette with hydraulic disc braking for instant, confident control from the first pedal stroke to the line.
Key Features
- ▪ STEALTHpro High-Modulus Carbon Frame (Disc & Thru-Axle 12×142) with full internal cable routing and aero-racing tube shaping.
- ▪ 1×13-Speed Drivetrain with an 11–46T SUNSHINE cassette for a wide, simplified gear range and a clean chainline.
- ▪ Integrated Carbon Cockpit — handlebar & stem (420×90mm) with full internal routing and hidden clamps for a slippery front end.
- ▪ Hydraulic Disc Brakes (160/160mm) for powerful, all-weather stopping with consistent modulation.
- ▪ Wireless or Mechanical Shifting — choose WheelTop GEX electronic wireless or RS SENSAH HRD6900-G mechanical hydraulic.
- ▪ 700C Alloy or Carbon Wheel Options on sealed-bearing thru-axle hubs, wrapped in CST 700×28C tires.
Engineering & Design Highlights
Integrated Aero Cockpit
A fully integrated carbon handlebar and stem (420×90mm) with hidden clamps and complete internal cable routing. The clean, uncluttered front end cuts drag and locks you into an efficient, aggressive road position.
1×13 Aero Drivetrain
A 13-speed rear derailleur tracks a wide-range 11–46T SUNSHINE cassette on a SUMC 13-speed chain — with no front derailleur. The single-ring 1×13 setup keeps the chainline clean and shifting simple across flats, climbs, and sprints.
Hydraulic Disc Braking
Full hydraulic disc brakes with 160mm rotors front and rear deliver powerful, consistent stopping in any condition. Thru-axle hubs and lightweight spoked 700C wheels keep handling sharp and confident.
