Capable, efficient and versatile.
Stable, confidence-inspiring handling and progressive geometry pair with efficient, responsive suspension to deliver consistent grip and control – smoothing climbs, taking the edge off long days in the saddle, and keeping you composed on every ride.
Designed and proven in the UK.
Shaped by the demands of British riding, Syphon combines contemporary frame design, full weather-proofing, and carefully selected, proven components – delivering a quietly confident, highly capable high-value and reliable ride wherever the trail takes you – and through whatever conditions you ride through.
Perfect fit for all
Syphon uses true proportional sizing, with size-specific geometry and front‑ and rear‑centres developed together to keep every rider centred between the wheels.
Reach, seat-tube angle and chainstay length are tuned in parallel, maintaining consistent weight balance, grip and stability across the range. The result is perfect fit and a planted, predictable ride for everyone.
Equipped to perform
Every Syphon is equipped with trail-proven, real-world kit that will serve you flawlessly, right from the shop floor: trail-tough, reinforced tyres; reliably powerful four-pot brakes; full-length dropper posts; wide handlebars, and usage-appropriate forks that are also ready for internal cartridge upgrading as your riding progresses.
Switchable geometry
Fine-tune your ride with the Shape.It flip-chip. Low for a slacker, more planted feel on descents. High for more ground clearance and efficiency on longer rides.
Changeable wheel size
Switch from full 29er to MX for a more agile, gravity-focused ride. Just swap in our MX Shape.It link (62-66mm; WAMLINK07) and a 27.5in rear wheel while keeping full high/low geometry adjustment.
Please note: MX conversion available on M, L and XL frames. Size S is MX as standard.
Perfect handling, perfectly scaled
Developed using our Total Geometry approach, where fit, balance, and handling are designed together as one.
Sythe is built around true proportional sizing – with size-specific geometry and carefully balanced front- and rear-centres to keep every rider perfectly centred between the wheels. As frame sizes increase, reach, chainstay length, seat-tube angle and weight distribution are tuned together – maintaining consistent handling, grip and stability across the range.The result is a bike that stays planted and predictable, no matter your size.
Neutral weight balance delivers confident front-end grip without overloading the rear, while matched front–rear centre ratios keep cornering feel, tracking and composure consistent at speed.
When trails turn steep, rough and fast, Sythe holds its line – delivering calm, controlled handling whether you’re pushing through bike park laps, technical descents or flat-out enduro stages.
