Whyte Syphon S Trail Mountain Bike
The Whyte Syphon S is a highly capable full suspension trail mountain bike built for riders who want confident handling, dependable components and serious performance across a wide range of terrain.
Designed as an all-round trail bike with enough capability for more demanding technical riding, the Syphon S combines 140mm of front suspension travel, 135mm of rear travel, progressive geometry and Whyte's proven Quad-Link 4 suspension platform. The result is a bike that feels composed on rough descents, efficient on long climbs and balanced across fast, technical singletrack.
Built around a durable 6061 hydroformed aluminium frame, the Whyte Syphon S offers excellent value while still delivering the geometry, suspension performance and adjustability expected from a modern high-performance trail mountain bike.
140mm RockShox Pike Suspension
Up front, the Whyte Syphon S uses a RockShox Pike Base 29-inch suspension fork with 140mm of travel.
Featuring DebonAir+ technology and a Rush RC damper, the Pike helps provide smooth, controlled suspension performance over roots, rocks and larger impacts.
At the rear, a RockShox Deluxe Select RT shock provides 135mm of travel and is custom tuned for Whyte to work with the bike's Quad-Link 4 suspension system.
Together, the suspension provides the traction and control needed for technical descents while remaining supportive and efficient when climbing or covering longer distances.
Progressive and Proportional Geometry
Whyte has developed the Syphon S using proportional sizing, meaning each frame size receives carefully considered dimensions to provide balanced handling for riders of different heights.
Reach, front centre, rear centre and overall geometry are adjusted across the size range to help maintain predictable weight distribution and handling.
The result is a bike that feels natural and composed whether you're climbing technical trails, carving through woodland singletrack or pushing harder on fast descents.
Shape.It Adjustable Geometry
The Syphon S features Whyte's Shape.It flip-chip geometry system, allowing riders to alter the bike's handling depending on terrain and riding style.
Switching from the high to low setting slackens the geometry by approximately 0.6 degrees and lowers the bottom bracket by around 8mm.
The higher setting provides a more efficient, all-day trail position, while the lower setting creates a more planted and gravity-focused setup for steeper and more technical terrain.
Shimano Deore 1x12 Drivetrain
Reliable shifting is provided by a proven Shimano Deore M6100 12-speed drivetrain.
The wide-range 10-51T cassette provides plenty of gearing for steep climbs, while the 30-tooth narrow-wide chainring keeps the drivetrain simple and secure.
Shimano's Shadow Plus rear derailleur helps reduce chain movement and improve chain retention when riding rough or technical terrain.
Powerful TRP Four-Piston Brakes
Stopping power comes from TRP EVO Comp four-piston hydraulic disc brakes.
A large 203mm front rotor is paired with a 180mm rear rotor, giving the Syphon S plenty of controlled braking power for steep descents and higher-speed trail riding.
Sintered brake pads also help maintain dependable braking performance in wet and muddy conditions.
29-Inch and MX Wheel Options
Medium, Large and Extra Large versions of the Whyte Syphon S come equipped with 29-inch wheels front and rear, helping the bike carry speed and maintain stability over rough terrain.
The Small frame uses a factory MX or mullet setup, with a 29-inch front wheel and 27.5-inch rear wheel to help improve fit, manoeuvrability and cornering performance.
Medium, Large and Extra Large bikes can also be converted to an MX setup using Whyte's appropriate Shape.It link and a suitable 27.5-inch rear wheel.
This gives riders additional flexibility to tune the Syphon S towards either speed and rollover capability or a more playful, agile ride.
Schwalbe Albert Radial Tyres
The Syphon S is equipped with Schwalbe Albert Trail Radial 2.5-inch tyres.
A Super Soft compound front tyre maximises grip and steering confidence, while the rear uses a Soft compound to balance traction, rolling performance and durability.
The wide tyres provide plenty of grip across loose surfaces, roots, rocks and typical UK trail conditions.
Dropper Post Included
Every Whyte Syphon S is supplied with a TranzX dropper seatpost.
Drop length is matched to frame size, with a 150mm dropper on Small frames and 170mm dropper posts on Medium through Extra Large.
This allows riders to lower the saddle quickly before descending, improving freedom of movement and control on technical sections.
Built for UK Trail Conditions
Whyte has engineered the Syphon S for year-round riding.
Weather-sealed cable and hose ports, sealed seat clamp areas and generous tyre clearance help reduce the effects of water and mud.
The frame also includes robust downtube and chainstay protection, helping prevent damage from rock strikes and chain slap while keeping the bike quieter on rough terrain.
Phosphate-coated pivot bearings packed with marine grease are designed to improve bearing life in wet conditions.
