The 604 active has the same construction as the top of the range 602 active. Just the padding is kept a little softer. This makes the 604 ideal for both medium length and short rides on the trekking and city bike. The design is plain and black so it will aesthetically suit any bike. The high quality cover material has already proven itself on the new Ergowave models. This provides the 604 active with an exceptional value for money. A perfect pressure distribution from a medical perspective is ensured through use of SQlab's tried and proven step saddle profile. The sensitive soft tissue areas are equally relieved for both men and women. Thanks to SQlab's active saddle technology, the saddle can follow the pedalling motion and the degree of movement can be adjusted to the rider's weight. This slight movement allows the spinal discs to be mobilised while also reducing the pressure to the sitbones. Material Rails CrMo Material Padding Trekking Foam max.
