I commute and ride my long distance rides via my portly mountain bikes. Two of my portly (36 & 32 pound) mountain bikes are rigid steel alloy frame 26ers, the other is my 35 pound 29er hardtail which doesn’t have a lockout feature, but I have no need for this feature.

When I go on my longer rides (126.5 miles through my recent 200-mile ride), I elect to ride my 29er hardtail since its front suspension in conjunction with its large volume 29” x 2.1 street tires yield a wonderfully smooth ride over all those miles and its smooth ride is particularly appreciated during gravity-bombing high-speed descents.
