Wheeler comes with a new rear suspension system

In addition to the new "Raptor" product line, Wheeler is also presenting a new rear suspension system. This is called "Super Single Pivot" and is used on the four model series "R.A.M.P", "Passera", "Hornet" and the new "Raptor" line.

With the "Super Single Pivot" kinematics, Wheeler is presenting a rear suspension system that they are now using on all non-racing bikes. This is a multi-supported single pivot system in which the bottom bracket axle is also the main pivot point of the rear triangle. The rear triangle is thus widely supported with the BB91 press-fit bottom bracket shell on large bearings in the frame. This provides the necessary stiffness, prevents pedal kickback and makes it efficient - even uphill. In addition, there is no chain elongation due to the system, which means that the chassis does not harden during downhill braking maneuvers and remains active. According to Wheeler, the kinematics work very linearly and are designed for slightly progressive shock absorbers. This should allow the rider to use the entire suspension travel, giving them a lot of flow.

Optical highlight
The "Super Single Pivot" system will be used on four Wheeler model series in 2012. With 140 millimetres of travel as the "R.A.M.P" series for men and as the "Passera" line for women, as the "Hornet" with 160 millimetres of travel and in the new "Raptor" series, which has 180 millimetres of travel. All four are visually similar and feature the latest technology: beautifully curved tubes, internally routed shift cables, post-mount brake socket mount, tapered head tube and, as befits these suspension travel ranges, there is also a Vario seatpost.

Wheeler is also breaking new ground in terms of the layout, with the new bikes coming across as unusually simple. A few well-coordinated colors and only the most necessary lettering adorn the frame. However, the individual anodized splashes of colour show a lot of attention to detail. Two lightweight carbon models are always available and, depending on the line, two to three aluminum variants. In the case of the "Raptor LTD", Wheeler specifies a target weight of 14 kilograms, which is more than respectable for 180 millimetres of suspension travel.

All in all, a successful step into the future with new high travel bikes.
