614 Ergowave Active 2.1 S-Tube Saddle

What Our Gearhead® Experts Are Saying:

"I recommend this saddle to riders logging serious gravel miles. The 55 SQ-Shore firmness keeps power transfer efficient, and the stepped ERGOWAVE profile stabilizes my sit bones on long efforts. The Active 2.1 system adds noticeable compliance over chatter without sacrificing support. With multiple width options, it’s easy to dial in fit for optimal comfort and performance."

Built for the demands of modern gravel riding, the SQ Labs 614 ERGOWAVE Active 2.1 S-Tube Saddle delivers a precise balance of ergonomic efficiency and long-distance comfort. Its stepped ERGOWAVE® profile creates a clearly defined seating platform, positioning the sit bones for optimal support while providing 65% relief in the perineal area. The 55 SQ-Shore firmness and Superlight Foam padding are tuned for endurance efforts, maintaining support over rough washboard, chunky doubletrack, and long mixed-surface routes.

The slim, tapered nose enhances leg clearance in an aggressive riding position, making it equally suited for high-tempo gravel races and steady endurance spins. At the core, the Active System 2.1 in the Sport configuration introduces controlled lateral flex that mirrors natural pelvic movement, helping reduce stress on the lumbar spine during extended rides. A glass fibre reinforced PA12 shell provides structural integrity, while hollow S-Tube stainless steel rails keep weight competitive and durability high, even under demanding DIN/ASTM category 4 conditions.

With width options from 12cm to 16cm, the 614 ERGOWAVE Active 2.1 can be precisely matched to sit bone measurements for optimal fit. Gravel-specific tuning, e-bike compatibility, and a 100kg maximum rider load make it a versatile choice for everything from fast gravel grinders to fully loaded bikepacking adventures.
