SEP.2 – Parallelogram elastomer suspension seat post

Product description – SEP.2 Parallelogram suspension elastomer seatpost

More comfort for urban, gravel, “e-” and cargo bikes

The SEP.2 elastomer suspension seatpost combines proven by,schulz parallelogram technology with modern shock absorber elements. This makes for an exceptional, more comfortable riding experience. Thanks to the precise parallelogram mechanism and the high-quality elastomer suspension elements, shocks are effectively absorbed, making it ideal for cross-country, cobblestone and gravel tracks.

Effective suspension & individual adjustment of the damping elements

With a compact height of just 99 mm and a spring travel of 27 mm, the SEP.2 is ideal for a wide variety of bicycle frames. The response behavior can be selected in 3 spring rates.

• Fine adjustment for a more precise tuning of the driving behavior
• Three elastomer stiffness grades available for different rider weightsli>
• Easy change of elastomer for adjustment for riders from 45 kg to 125 kg

Comfort & longevity in one

The Elastomer damper element reliably absorbs shocks while riding without sacrificing precision and control. The high-quality workmanship with robust, forged aluminum and maintenance-free IGUS plain bearings ensures a particularly long service life. The SEP.2 also impresses with its dynamic response behavior and modern design, which reflects functionality and aesthetics.

Comfort for every bicycle

If the seat post diameter does not match the diameter of the bicycle frame, this can be easily corrected with a by.schulz G. Shim reduction sleeve equalize. A special SEP.2 Neoprene Mudcover offers optional protection against dirt and environmental influences. This ensures uninterrupted riding pleasure and a long service life for the mechanics.

Conclusion: The SEP.2 Parallelogram spring seatpost from by,schulz offers maximum comfort and flexible customization options, Sustainability through premium quality – perfect for anyone who wants to enjoy their bike tours.

Function

The parallelogram-sprung SEP.2 elastomer seatpost was designed with 27 mm of suspension travel, which enables a high level of riding comfort. The elastomer damping element is progressively designed thanks to its patented shape, it reacts sensitively to light impacts and with increasing damping to hard impacts.
Due to the design of the shock absorber and the use of a highly resilient technical elastomer, even hard impacts, for example when driving through deep potholes, do not cause the shock absorber in the parallogram system to break through.

Three elastomer damper elements with different, coordinated degrees of hardness are available for optimum adjustment of the SEP.2’s spring and damping comfort to the rider’s weight. These are easy to fit and can be individually fine-tuned in two different positions.

The table provides guidance for selecting the right shock absorber element, whereby the rider’s weight, riding position and riding profile should be taken into account when making a decision.

Maximum permissible rider weight 125 kg =
Weight of the rider + additional weight (e.g. clothing, rucksack).

Spring stiffness: Soft (color: grey/grey): For lighter riders with low weight.

Spring stiffness: Medium (color: dark grey/dark grey): For riders of medium weight.

Spring stiffness: Hard (color: black/black): For riders with high weight

Note: Please note that the damping behavior of elastomers is temperature-dependent. This means that the response behavior can change over the course of the year. The SEP.2 elastomer damping elements are suitable for temperatures from -5 to + 50°.

Installation requirement

• · When installing the seat post, make sure that the inner diameter of the seat tube of the bicycle frame and the outer diameter of the SEP.2 seat post are the same.
• Different dimensions can lead to failure of the clamping system and to accidents and damage to property or
  personal injury.
  personal injury.
• If the seat tube diameter is too large, it can optionally be adapted to the tube diameter of the seat post using a reduction sleeve. The precisely manufactured, double-slotted seat tubes are used to adjust the seat tube diameter.
  Aluminum reduction sleeves from by,chulz with an overall height of approx. 100 mm are recommended.
