Abstract
The invention relates to bicycle seats, particularly for racing or long-range touring. Rider comfort and fit to the bicycle is a problem of long standing. A seat assembly (13) provides an elevated region (11c) and a sloping area (11b), contacted by the rider's ischial tuberosities and pubic symphysis respectively, which encourages proper posture and enhances rider comfort. Adjustable tube (52), inserts (55, 56, 61, 67), and sling (46) further fit the rider to the seat and bicycle.
