Our goal is simple: if something isn't right, we make it right.
- Arrived defective, damaged or incorrect? Tell us within 7 days of delivery with photos (keep the packaging).
- We resolve it: repair, spare part, replacement or refund — whichever fits the case.
- If the bike is unusable and we can't resolve it: full refund and collection, or a replacement.

Twitter Gravel X
Engineered to blur the line between road speed and off-road freedom, the Twitter Gravel X is a high-modulus carbon gravel machine built for the long way round. Its Pro-Gravel monocoque frame and XC-geometry carbon fork pair full internal cable routing with a threaded T47 bottom bracket for stiff, reliable power transfer, while INNOVA PRO 700×40C tires and full-hydraulic disc braking keep you composed on tarmac, hardpack, and everything in between. Offered with a mechanical RS SENSAH 2×12, a wireless WheelTop GEX 1×13, or a SRAM APEX 1×11 drivetrain, it adapts to however you like to ride.

- ▪ High-Modulus Carbon XC Fork (Disc & Thru-Axle 12×100, 700C) for precise, confident handling on mixed terrain.
- ▪ Three Drivetrain Builds — RS SENSAH 2×12 mechanical, WheelTop GEX 1×13 wireless, or SRAM APEX 1×11 hydraulic.
- ▪ PRO Flat-Mount Full Hydraulic Disc Brakes with 160/160mm rotors for strong, modulated all-weather stopping.
- ▪ RS Disc Wheelset on 4-sealed-bearing thru-axle hubs with AL7005 double-wall rims and INNOVA PRO 700×40C tires.
