With twenty nine inch wheels and 120mm of travel, the updated 29r from Turner is for everyone who loves the 29 inch wheel characteristics and now can utilize those big wheels with a class leading 120mm of dw-link travel. David Turner and Dave Weagle really did their homework on the Sultan.
Carefully blending the dynamics of rider positioning with the special anti-squat needs of the 29 inch wheeled bike. Special attention was paid to the relationship between bottom bracket height, chainstay length and dw-link placement resulting in super efficient power transfer through those big wheels, yet always fully active suspension that devours everything mother earth has in front of it.

Finally a 29 inch trail bike that can acually ride down the mountain as well as it pedals up. The Sultan is here.
The journal bearing design offers incredible strength and long life with very little maintenance.
Standard bearings are designed with high-speed rotation in mind (skateboard wheels, drill motors etc.) The journal bearing we use has a purpose of holding a very tight tolerance along with carrying a load much greater than that produced by a bicycle frame, these two attributes we feel are essential to a great riding bike.
The rear of our frames often gets praise for how stiff it is aterally and how well it tracks through the roots, ruts, and rocks encountered on a mountain bike. Because a bearing found in a bike pivot never makes a full rotation, you rely on two maybe three of the balls in the cartridge to carry the entire load and pressures generated by the rider. Over time this is what creates that "crunchy" feel or "squeaky" sounds people often comment about.
Standard bearings are also made of steel, steel rusts after being exposed to water, grit and grime, again found in our everyday riding. So long lasting, tight tolerance and incredible load bearing
capabilities are why we have chosen to stick with journal bearings
Simultaneously engineered anti-squat and wheel rate curves are the mathematical formulas that make the dw-link the world’s most efficient and traction-aiding suspension system.
Position Sensitive Anti-Squat:
Newton’s 3rd law states that every action has an equal and opposite reaction. When a vehicle accelerates, the reaction is that its mass is transferred rearward. dw-link’s patented position sensitive anti-squat perfectly balances this rearward mass transfer, increasing efficiency, traction, and bump sensitivity, and eliminating pedal feedback.
Each dw-link frame is engineered for an optimum wheel rate and to work for a specific use with a specific spring and vdamper. Unlike other suspension systems, dw-link’s does not rely on pedaling platform type dampers, giving the best bump absorption and traction of any suspension available today. Advanced riders use these traits to pump terrain in the trail and add momentum.
The dw-link suspension projects its instant center to an ideal location, achieving a balance of traction and stability under hard braking that is unmatched by other suspensions.
Least Pedal Feedback:
Perception of pedal feedback on a bicycle is a manifes- tation of rapid chainstay length change and gearing effects. dw-link uses a smooth and positive chainstay lengthening effect to offset negative gearing effects. This results in a smooth ride with imperceptible pedal feedback over the entire gear range.
As the dw-link suspension reacts to obstacles, its position sensitive axle path intelligently changes to meet the demands of the trail. In the beginning of the travel, its rearward profile gives
incredible small bump absorption and traction on theclimbs. In the middle of the travel, the dw-link axle path works with the front suspension to provide a balanced feel for amazing cornering confidence and jumping ability. The end of the travel provides an increase in compression damping for bottomless suspension feel and big hit absorption.
dw-link uses short, stiff links, and a triangulated rear swingarm. This unique layout aligns suspension forces in the most efficient manner possible to enable frame designs with industry leading strength-to-weight ratios and stiffness. This structural advantage lets dw-link riders put down power more efficiently and track straight in the bumps where others veer off course
