The Sesta has performed excellently in the Cape Epic stage races it took part in with multiple top 10 finishes. On the World Cup circuit it has also achieved great results for OMX Pro Bike Team. The Sesta is the latest full-suspension race machine from Silverback, featuring a lightweight full carbon design.

Insight into the technology of SESTA
Using a large main pivot to connect the solid rear triangle with the compact rocker linkages to the seat tube, creates a stiff and efficient platform for the suspension. The rocker pivot points are close together, enforcing lateral stiffness through the design.
The use of high performance, durable and tough bushings on the upper shock pivot, joins the two rocker linkages in a stiff and lightweight union. These same bushings are used to connect the seat stays to the upper linkage. Bushings are perfect for limited movement pivots in that they remain smooth over the countless small, pressured movements that pivots undergo. The Large main pivot 6902 MAX bearings and medium 6900 seat tube bearings are used to maintain smooth and accurate tracking of the terrain.
Calculated suspension design allows us to use short 442mm chainstays that help keep the rear of the bike agile through corners, and give the bike excellent manoeuvrability. The short stays also help give a snappy acceleration, enhancing the bikes racing nature and technical abilities.
The strut not only adds strength and stiffness to the rear triangle while braking, but also, with its curved shape, directs air onto the rotor for additional cooling while descending helping to have more consistent brake performance and helping prolong pad life.
These rocker arms wrap around the seat tube, connecting the rear triangle to the rear shock and seat tube. Their short length optimises stiffness, and together they allow the rear triangle to move freely while controlling the leverage ratio perfectly.
Rear thru axle provides a stiff and secure fastening of the rear wheel. The custom design integrates a threaded hanger that can be easily replaced should there be damage. The frame supports the 142 x 12mm standard and enhances rear wheel tracking in rough trail conditions for added rider control.
The rear triangle has no pivots that break the triangular shape, making the construction as light and stiff as possible, perfect for a lightweight racing machine. A large and round chainstay bridge connects the two asymmetrical chainstays. The left side chainstay has a direct line to the main pivot to optimise the weight to stiffness ratio.
This option allows one to use a direct mount front derailleur, or to remove it for weight reduction when using a single chainring up front and making the frame look more aesthetically pleasing at the same time.
By use of internal mandrels during construction, the maximum carbon fibre strand length can be used along tubes and around junctions. This ensures minimum material waste and enforces our optimal weight to stiffness ratio properties. Various directional layers of carbon fibre used in this manner produce strong, stiff, light and reliable frames.
We are Branched Unified Rear Triangle Technology. Keeps the rear triangle as one piece with no pivots to break the triangular structure, joined with a single main pivot at the bottom bracket area together with short and stiff linkages at the top to control the leverage ratio and keep the front and rear triangles connected solidly. This setup is light, stiff and strong. This layout has great lateral stiffness when combined with our pivot locations and short linkages. This keeps the frame feeling in alignment under big bumps, hard cornering and rough terrain.
High Leverage Rate at Stroke Initialisation - makes for a supple and active platform. Long days of riding are more comfortable and less tiring.
Helps with big hit control by precisely regulating the amount of travel used - reserving the final 30% for when you really need it.
Since air shocks are inherently progressive BURST is a perfect fit - the slightly regressive end-stroke works in conjunction with the air shock, avoiding harsh compression spikes and allowing for full travel usage.
