MT390 - Twitter Alloy Mountain Bike
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.
Engineering & Design Highlights
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
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
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.
Drivetrain Configurations
SHIMANO M315 — 3×8-Speed
SHIMANO M315 3×8 with SHIMANO TY500 front and TY300 rear derailleurs, an RS alloy square-axis 24-34-42T triple crankset, SUGEK 8-speed 11-32T cassette and SUMC chain on a Kenli square-axis BSA68 bottom bracket — a dependable, wide-range trail group.
RETROSPEC (LTWOO) — 3×10-Speed
RETROSPEC (LTWOO) 3×10 shifting with matching front and 10-speed rear derailleurs, an RS alloy hollow 24-32-42T crankset, SUGEK 10-speed 11-36T cassette and SUMC 10-speed chain on a hollow BSA68×24 bottom bracket — the deepest gearing on offer.
SHIMANO CUES U4000 — 1×9-Speed
SHIMANO CUES U4000 1×9 with U3020 9-speed rear derailleur and no front derailleur, an RS alloy square-axis 38T single-ring crankset, SUNSHINE 9-speed 11-36T cassette and SUMC 9-speed chain on a Kenli square-axis BSA68 bottom bracket — simple, quiet, modern shifting.
