The Top Choice: Polygon Siskiu T8 UDH
The Polygon Siskiu T8 is a high-performance, do-it-all trail bike. Its UDH-ready ALX frame with 140 mm front and 135 mm rear travel, reinforced rear stays, and fully internal cable routing delivers a clean, durable build. Fox 34 Float Rhythm fork, Float DPS rear shock, and Shimano SLX 1×12 drivetrain on Microspline hubs provide smooth suspension and crisp shifting. Modern geometry—with a slacker head angle, steeper seat tube, and longer reach—boosts confidence on descents while keeping climbs efficient. Maxxis tyres and a dropper post offer traction and control across flowy singletrack and technical terrain. Lightweight, nimble, and packed with premium features, the Siskiu T8 makes high-performance trail riding accessible to riders of all levels.
The Down Country Ripper: Superior XF 9.7 DC
The Superior XF 9.7 DC frameset blends lightweight efficiency with race-proven control. Its 1620 g carbon frame uses Advanced Race Geometry and a 110 mm DT Swiss F232 ONE fork paired with an R232 ONE rear shock for precise, balanced handling. Shimano XT and SLX 12-speed components deliver crisp shifting, while DT Swiss M 1900 SPLINE wheels and Schwalbe Racing Ray tyres keep you fast and planted on technical terrain. With internal cable routing, dropper-post readiness, and a clean, modern build, it’s a down-country platform built to dominate climbs and shred descents alike.

It pairs 150 mm front travel with 140 mm rear travel and uses a Bosch Performance Line CX motor that delivers 85 Nm of torque.
