Endless Summer - a deep feeling
1966, Bruce Brown writes movie history with his surfer movie, The Endless Summer. Hardly anyone else conveys the feeling of the 1960s like he does. Freedom and adventure, lots of fun and a summer that shouldn’t ever end. The ERGOWAVE® Endless Summer limited edition in Endless Summer Green is SQlab’s invitation to consider that MTB isn’t merely a sport, but living the shared feeling of “being in the saddle.” For the well-seasoned trio of developers at SQlab, Tobias Hild, Tibor Simai and Mitch Schlecht, mountain biking isn’t just a hobby in addition to a profession, but biking is rather an attitude to life that unites the three of them. Entirely in line with the motto of the movie by Bruce Brown, we want to reawaken the feeling of The Endless Summer and carry it over to the MTB world.

The perfect saddle width
A prerequisite for maximum comfort and relief is the coordinated saddle width, so that it is guaranteed that your seat bones lie completely on the saddle. This is the only way to properly relieve the sensitive perineal area in men and the usually lower pubic arch in women. Available widths: 12 / 13 / 14 / 15 cm


Sportive rear
The raised back section provides more rearward support and ensures efficient power transmission.The level and lowered saddle nose applies less pressure to the sensitive areas of men and women alike.
Saving Energy
The wave shaped ERGOWAVE® profile which contours from the rear to the front offers a perfect form-fit shape for most sitbones. The rider does not need to be seated in an inefficient and tiring sitting position and all energy can be used for forward propulsion.

SQlab active Technology
The biomechanically similar lateral pelvic movement of the SQlab active technology by up to 7° increases the efficiency of the pedalling movement. At the same time, the strain on the intervertebral discs is relieved and the comfort at the sit bones is increased.

The 611 ERGOWAVE® Endless Summer is identical to the 611 ERGOWAVE® active apart from the Kevlar protection with integrated active technology. The wave-like shape and raised rear section provides perfect rearward support and an optimal pressure distribution which reaches deep into the body structures resulting in improved power transmission. The lowered nose in combination with the dip provides optimal pressure relief for the perineal area. For an even better pressure relief, especially on long technical climbs, the saddle nose of the 611 was made approx. 4 mm wider than that of the 612, but just as flat and with largest possible surface area. The padding was designed for the specific needs on the MTB with better dampening properties than the 612 making it perfect for rough off-road terrain. In place of the Kevlar side protection, a very smooth material was selected which is still extremely durable but at the same time has great dirt-repellent properties.
