Mountain / Hardtail / Alloy MTB

Twitter MT390

Built to make the trail feel easy, the Twitter MT390 is a lightweight AL6061-T6 alloy hardtail with smooth-welded, internally routed lines and a true 13.6 kg build weight. A TW coil suspension fork with manual lockout smooths out the rough while keeping climbs efficient, and TEKTRO hydraulic disc brakes (160/160 mm) deliver confident, all-weather stopping. Rolling on RS double-wall alloy wheels wrapped in 29" (27.5") CST 2.1" tires, the MT390 comes in three drivetrain builds — from a proven SHIMANO 3×8 to a 1×9 SHIMANO CUES — so you can spec it for exactly how you ride.

Key Features

  • AL6061-T6 Alloy Hardtail Frame with smooth welding and internal cable routing for a clean, durable, lightweight 13.6 kg build.
  • TW Coil Suspension Fork with manual lockout — plush over rough trail, firm and efficient when you flip the switch for climbs.
  • Three Drivetrain Builds — SHIMANO M315 3×8, RETROSPEC (LTWOO) 3×10, or 1×9 SHIMANO CUES U4000 — pick your range and shifting feel.
  • TEKTRO Hydraulic Disc Brakes (160 mm front / 160 mm rear) for strong, consistent stopping power in any condition.
  • 29" (27.5") RS Alloy Wheelset on double-wall rivet rims with sealed-bearing hubs, wrapped in grippy CST 2.1" MTB tires.
  • Trail-Ready Alloy Cockpit — matte alloy 720 mm handlebar, 60 mm stem and comfortable grips for confident, upright control.

Wheels & Disc Brakes

RS alloy double-wall wheels (W25×H21mm) on sealed-bearing disc hubs, wrapped in grippy CST 29"(27.5") × 2.1" knobby tires, with TEKTRO hydraulic disc brakes (160/160mm) for confident all-weather stopping.

Wide-Range Drivetrain
Wide-Range Drivetrain

An RS alloy crankset drives a broad-range cassette for gearing deep enough to spin up steep climbs and roll fast on the flats. Spec a triple-ring 3×8 or 3×10 for maximum range, or a clean single-ring 1×9 SHIMANO CUES build for simpler, quieter shifting.

Coil Suspension Fork
Coil Suspension Fork

A TW alloy coil suspension fork with manual lockout takes the edge off roots and rocks, then firms up on demand so none of your effort is lost on smooth climbs. A 29" (27.5") wheel on a sealed-bearing hub keeps you rolling fast over rough ground.
