For our GLEN there is now a new model generation. Direct to the new GLEN: click here! 

We still have a few frames from the GLEN V1 in stock - all available sizes and colours can be found under the article "GLEN Frame" on this page. 

Following our well-proven philosophy, the GLEN features progressive kinematics. Rocker tuned suspension provides a fine response behavior for little shocks. In the middle part, the kinematics offer a lot of feedback and the spring travel allows for a smooth ride and easy take off at lips. The generously dimensioned progression at the end provides good bottom out protection and reserves. Thanks to the kinematics, the suspension type can be chosen freely – air or steel spring – since the progression comes from the kinematics and not from volume spacers in the air shock. This means that the suspension system remains progressive even with linearly coiled steel springs.

Before using an shock thats not delivered by us it's necessary to compress the shock completely and check for sufficent clearance.

The position of the pivot point on the main frame guarantees high pedaling efficiency. Anti squat and ant rise values that were achieved this way draw the image of a carriage so efficient that it is often unnecessary to use the damper platform.

The generous installation space enables the installation of most dampers – even with piggyback. The rocker arms keep away dangerous shear forces from the damper. For perfect adjustment, the lower damper mount is milled on the completely welded and heat-treated frame using a CNC machining center. The damper is protected against rockfalls by its position in front of the seat tube.

With 150 mm at the front and 140 mm at the rear, the GLEN brings along a suitable suspension travel for all-round use without losing focus on efficiency and playfulness. The 29” wheels provide optimal roll-over resistance and make the bike fast.

At the same time, the bigger wheels and thus higher front axle help to avoid rollovers on steep slopes and unexpected obstacles. In relation to the axles, the bottom bracket of the 29” frames sits lower and provides the biker with a good stand on the bike.

The GLEN is certified for ASTM class 4 which normally is put on one level with Enduro. If you want to built an even more potent bike, you can use suspension forks with up to 160 mm of suspension to be used in racing or at bike parks. All wheel options and attachment parts are robust and designed for the expectable loads. The SL complete bike was designed as a particularly lightweight trail and all mountain bike.

Total Bearing Quality 

By Total Bearing Quality we mean everything that is necessary for high quality and thus durable bearings. This includes roller bearings, bearing seats, mounting, and protection against dirt.

Frame Material and Fabrication

We process the aluminum alloy 6013 which is welded using TIG process. The smooth welding strategy we use is beneficial for the stability and creates notch-free joints.

After that, the frames receive a T4 heat-treatment at 500 degrees Celsius, followed by the straightening in solution annealed condition. To achieve a special vibration endurance of alloy 6013, it is then T6 heat-treated. Eventually, the frame is inspected again and head tube fit and bottom bracket bearing are manufactured.

Bottle Cage

A drinking bottle can be fitted to the down tube. Threaded sleeves are welded into the frame which makes them particularly robust. The size of the mountable bottle depends on the size of the frame and the dampers used. For size M it normally is necessary to use a damper without piggyback. Conventional bottle cages position the bottle in a place comparable with that of the fastening threads. Alternative systems, e.g. Fabric or Fidlock, might follow different approaches. We recommend testing the intended combination and making sure that the damper does not make contact with the bottle.

Through Axle and Rear Width

The GLEN frame is compatible with 148 mm Boost spacing. Using a different derailleur eye and a special spacer it can be converted to 142 mm hub spacing. Boost and non Boost cranks will fit alike. Q-Factor 168 is required.
The X-12 compatible through axle operates with a nut that is threaded in the drop out. In case you strip the threads they can be replaced by changing this part. The frame is delivered with a DT Swiss RWS through axle. The lever is a plug-in type. If you don´t want to use the lever, pul it out and simply tighten the axle with an allen key.

Disk Brake Mount

The GLEN features a disk brake mount according to Postmount 180 standard. As in the case of our other frames, the disk brake mount and the fork end are a monolithic milled part. To ensure the precision of the contact surfaces and threads, we machine them in Germany on a 5-axis CNC mill along with the fabrication of the bearing fit.

Bottom Bracket and ISCG Mount

Again we decided for the durable and easy to maintain option, the bolted BSC bottom bracket. The ISCG mount is embedded in the milled bottom bracket and robustly designed. In addition to Chain Guides, crash plates can be installed. There is an optional mounting hole on top.

Headtube and Headset

The head tube houses integrated headsets Type IS41/IS52 and does without press fitting which makes the system easy to maintain. Additionally, the head tube can easily be remilled for integrated headsets. The function surfaces with a slope of less than 45 degrees are machined immediately which is not possible with cylindrical tubes. The Head tube features asymmetrical wall thickness with a good load-bearing capacity.

Cable Routing

Free of narrow bending radiuses and well protected against rockfall, the cable routing sits on the down tube. This improves the shifting performance and allows for a quick and easy replacement of the brake without bleeding it. Cable guides are flexible and can be replaced with other guides if needed, e.g. for the cable of a remote shock remote control. The remote cable of the seat post is completely housed inside the frame.

Colors and Frame Decals

The frame is available in black anodized, Raw, blue, and red. Before the application of the powder coating, the frames are polished. The transparent paints allow the polished metal surface to shine through and add a certain brilliance to the colors. The Raw look is finished with Scotch Brite pads and comes out quite shiny. With time the surface of the Raw frame can get a Patina, but you can easily refurbish the frame with Scotch Brite pads.

Decals are available in different color variations. If you want to personalize your bike, you can download the vector data of the logotype and create your own color design. Click here to download the file.
