MTB rear suspensions | explanations


Perhaps because front suspension has been easier to implement and more readily adopted, it is often assumed that a bicycle with rear suspension has full suspension. Mountain bike technology has made great advances since first appearing in the early 1990s. 
Early full suspension frames were heavy and tended to bounce up and down while a rider pedaled. This movement was called pedal bob, kickback, or monkey motion and took power out of a rider's pedal stroke — especially during climbs up steep hills. Input from hard braking efforts (known as brake jack) also negatively affected early full suspension designs. When a rider hit the brakes, these early suspensions compressed into their travel and lost some of their ability to absorb bumps. This happened in situations where the rear suspension was needed most.(...)

A brief history #5 | KENT ERIKSEN cycles



Founded in 1981 by Kent Eriksen, who is now a member of the Mountain Bike Hall of Fame, Moots has been identified as a source for innovation in the bicycle industry since its inception. Specializing in titanium, and designing the YBB soft-tail yolk. Throughout its history, Moots has been known for the innovative bicycle components they design and manufacture. In the 1980s, Eriksen design the company's "Moots Mounts," clamp-on cantilever posts which could be removed or repositioned using only an allen wrench. Another innovation was an early version of what became known as "bar ends" in the 1990s. The product made by Moots clamped inside the brake levers and had large wooden balls at the ends. Kent started using titanium in 1991 following his revolutionary work fabricating frames out of steel. 


Eventually Kent left Moots in 2004, went on hiatus, to start his own custom frame shop and is now back with Kent Eriksen Cycles and still builds in Steamboat Springs,CO, not far from the Rocky Mountains. Forever the innovator, tester and designer, titanium use was a natural progression. Kent’s signature is his ability to shape, form and fit titanium tubes specific for each bike he designs. Kent Eriksen's shop is full of specialized benders, squishers and shaping tools used daily in the fabrication of custom frames.


The above bicycle is a full suspension 650B, Titanium bicycle. Up front, the Maverick DUC32 handles the steering, and has been modified to allow maximum travel mated to a 650B tyre. The rear utilized Ventana's faux-bar linkage along with Eriksen manufactured titanium seat stays (Ventana's OE version uses aluminum stays instead). 
This is truly a beautiful bike, and only one of the many 650B frame that Eriksen Cycle has produced.
