The German saddle manufacturer SQlab is developing the 612 Ergowave active 2.1 and the 602 Ergolux active 2.1 two models for different areas of use in the cold season. While Roller training requires a static posture, outdoor riding prioritises stability and relaxation. The different requirements are reflected in the design of both saddles.
The Active System forms the technical basis of both models and enables controlled lateral movement of the saddle. This function is designed to support the natural movement of the pelvis when pedalling and reduce tension in the lower back. For indoor sessions the additional dynamics compensate for the limited freedom of movement on the castor while following the natural riding motion outdoors.
The 612 Ergowave active 2.1 is aimed at road and mountain bike riders with an aggressive riding position. The wave-shaped Ergowave contour with a raised rear stabilises the pelvis and enables efficient power transmission. This geometry proves to be advantageous during intensive indoor sessions, as it creates a stable basis for high performance.
The deeper moulded nose and the central recess create space in the front area and avoid pressure peaks during sporty postures. The saddle uses a fibreglass-reinforced polyamide shell with super-light foam and microfibre cover. The S-Tube stays help to reduce weight and allow a length of 275 mm. The maximum rider weight is 100 kg and the area of use is focussed on road riding.
The 602 Ergolux active 2.1 uses a two-stage Ergolux contour for upright to moderately reclined sitting positions. The generous support surface distributes the pressure evenly and creates a calm sitting experience for longer everyday journeys. The stepped shape provides a stable seat surface at the rear, while the lower nose at the front provides relief.
The Active system can be adjusted in two stages and a switch lever simplifies the adjustment. The construction utilises solid CrMo struts and a polypropylene compound shell with lightweight foam padding. The hard-wearing microfibre cover can withstand everyday wear and tear. Integrated threads allow the mounting of an SQlab saddlebag with Fidlock adapter. With a length of 282 mm, the saddle can support a rider weight of up to 130 kg.
The difference in weight between the two models is around 250 g and reflects the different design objectives. The 612 Ergowave active 2.1 prioritises low weight and dimensional stability for sporting applications, while the 602 ERgolux active 2.1 focuses on long-distance comfort and robustness. The choice of materials supports this focus: glass-reinforced polyamide in the sports model ensures stiffness with low weight, while the polypropylene compound in the comfort model provides cushioning and durability.
The range of sizes also differs between the models. The 612 Ergowave active 2.1 is available in widths of 12, 13, 14, 15 and 16 cm, while the 602 Ergolux active 2.1 is available in 14, 15, 16 and 17 cm. The wider options for the comfort model take into account the requirements of more relaxed sitting positions, where the pelvis is loaded differently than in a sporty posture.
SQlab positions the sporty 612 Ergowave active 2.1 at 149.95 euros, the comfort-orientated 602 Ergolux active 2.1 at 129.99 euros. The price difference of 20 euros reflects the more elaborate choice of materials and construction of the sports model. The glass fibre-reinforced polyamide shell and the super-light microfibre justify the extra cost compared to the standard polypropylene construction.
Both models are available immediately and are aimed at different target groups. The 612 Ergowave active 2.1 appeals to ambitious riders who don't want to compromise on performance even in winter. The 602 Ergolux active 2.1 is suitable for commuters and occasional riders who value comfort on everyday routes. The combination of both models covers the entire spectrum of winter riding requirements.
