GLEN

Trailbike

The trail bike GLEN is based on our new frame platform. The many improved details and the contemporary geometry are inspiring uphill and downhill. The GLEN offers a lot of feedback and is especially fun on home trails. It is agile and playful and has the same robustness and stiffness as the downhill-oriented COAL.

"With the new generation we present our most versatile aluminium frames. The GLEN now has slightly more suspension travel at 145 mm and we have further refined the geometry - with the seat position closer to the front the new GLEN climbs excellent and we were able to adapt the bike even better to different body sizes. The progressive kinematics perform LAST typical efficiently. The GLEN is easy to throw through turns and the smallest features get you airborne."

Geometry

The geometry of the COAL is perfect for demanding enduro tracks, racing and bike parks. The steering angle of 64 degrees gives a lot of safety and control in difficult terrain. We deliberately chose a moderate bottom bracket height, so that a good compromise between positioning "in the bike" and sufficient ground clearance is achieved. For the COAL we adjusted the chainstay length, seat angle, bottom bracket height and head tube length to suit the size of the bike. The chainstay length of size 155 is a short 428 mm and increases gradually up to 444 mm for size 195. For the larger sizes we adjusted the seat tube a little steeper to get more pressure on the front wheel. The short seat tubes and the full retractability of the seat post give every rider the choice between several sizes - depending on their preference for a longer or shorter bike. The sizes 155 and 165 offer a 5 mm lower bottom bracket, as we recommend shorter 170 mm cranks due to the pedalling ergonomics. Together with the short seat tube and the very compact chain stays, this results in an exceptionally agile 29er or MX for small riders. To give a starting point for the size selection, we named the sizes according to prototypical body height of riders: 155, 165, 175, 185 and 195.

Suspension System

Progressive Suspension System

For almost 20 years we have been using very progressive suspension designs. Even today, for steel spring dampers, progressive kinematics is still the best option to realize sensitivity, support and bottom out protection. Shocks with air springs benefit when the excessive use of volume spacers can be avoided. Likewise, the forces introduced into the frame and the bearings via the damper are reduced when the transmission ratio decreases towards the end of the spring travel. This allows for a lighter design and less stress on the bearings. The COAL shows 41% progression from the SAG point to the end of the travel and is equally suitable for air and steel spring shocks.
Anti Squat

Size-specific Anti-Squat

In order to generate the best possible pedalling efficiency for each frame size, the kinematics are optimised to minimise the differences between the anti-squat curves. The graphs below show in blue the course of the anti-squat value for the five frame sizes in dependence of the gear engaged. This complex design is particularly advantageous for small and large riders, as their low resp. high center of gravity would otherwise be far from optimum.
Anti Rise

Anti Rise

The Anti-Rise value determines how the suspension behaves when braking. A value around 100% is considered the optimum, as the suspension then behaves neutrally. This means that the braking has no disturbing influence on the suspension system. Due to the size-specific optimization of the pivot point position, all five values of the COAL are practically congruent, shown in blue.

Geometry

The GLEN is a very agile trail bike with a 65 degree steering angle and a 77 degree seat angle. The seating position on the GLEN is shifted about 10 mm forward compared to the COAL. However, this increase in reach does not lead to greater stretching, as the top tube length is practically the same. The stack is about 8 mm lower and gives the sportier impression that you can feel in direct comparison. For GLEN we adjusted the chainstay length, seat angle, bottom bracket height and head tube length to suit the size of the bike. The chainstay length of size 155 is a short 427 mm and increases gradually up to 444 mm for size 195. For the larger sizes we adjusted the seat tube a little steeper to get more pressure on the front wheel. The short seat tubes and the full retractability of the seat post give every rider the choice between several sizes - depending on their preference for a longer or shorter bike. The sizes 155 and 165 offer a 5 mm lower bottom bracket, as we recommend shorter 170 mm cranks due to the pedalling ergonomics.

Features

Responsibility and Ecology

In choosing our partners and suppliers, we attach great importance to good conditions, both in terms of the environment and conditions for employees. That's why we prefer suppliers from free democratic countries. For the COAL and the GLEN, this means: frames are welded and anodized in Taiwan. CNC processing of bearing seats and screw joints is done in Germany. Custom paint jobs are executed in Hagen, Germany. Finally, all frames are assembled, tested and, if desired, assembled into complete bikes in Dortmund.
