Frame

When developing the new Siskiu T, we put ourselves in the riders shoes and went back to the drawing board, starting with a water bottle! Designed around our Wheel Fit Size System, the Siskiu T features 29” wheels on LG & XL frame sizes, MD sizes offering the choice of 29” or 27.5” and SM sizes being optimized around the agility of 27.5” only.
29” models feature 135mm of rear travel with 140mm forks whilst 27.5” bikes have 140mm in the rear with 150mm up front. Seat tubes have been significantly shortened to allow for 150mm dropper posts on SM and MD frame, 170mm on LG and XL. The frame also comes with a threaded bottom bracket, Boost axles front and rear and internal cable routing through the main frame.

Geometry

Geometry has progressed in the past few years and trail bikes are becoming more capable than ever. When developing the new Siskiu T we aimed to prove that you don't have to pay a premium for modern geometry. The Siskiu T handles the demands of a modern trail bike, striking the balance between high speed control and playful handling.
The reach was lengthened 25-30mm on all sizes and the trail has also been increased by a 1° slacker head angle combined with short offset forks, improving stability and confidence at speed and on steeper terrain. The chainstays were shortened to keep the bike fun but also ensure that the overall wheelbase isn't too long for general trail riding. The benefits of a steep seat angle can’t be understated, which is why the effective seat angle has been increased significantly to 76.5°. On the trail the Siskiu T feels just as responsive and agile as the previous generation but the overall ceiling of what the bike is capable of has been lifted.


Susupension

The Siskiu T utilizes the tried and tested Faux Bar design. The linkage is built around the One Piece Unibody Pivot Bridge that reduces the frame's weight but also improves stiffness and reduces lateral flex on the rear shock under load.

The kinematics of the bike maintain the poppy supportive nature of the previous generation, while improving the climbing efficiency and small bump compliance. The pedaling platform is efficient thanks to the 10% increase in anti-squat. Thanks to the increased anti-squat a lighter custom tune on the shock could be used to improve small bump compliance and allow the suspension to move more freely.

The leverage curve has been smoothed out slightly to still provide a high level of progression but improve sensitivity. The axle path has also been improved, staying rearward for longer, further enhancing performance over square edged hits.

 I think you'll do great things at this price point! I'd like to purchase a frame and build it up from scratch.

 Just got the T7 for my son's first "real" bike. It is just plain brilliant. This kind of bike would have been out of reach of all but the super wealthy just 10 years ago. Now it is a great starting point. Crazy times

 That T7 looks like it could be the new value benchmark for entry level bikes.
