When we first transferred the GEOLUTION concept to 29er Trailbikes with the first prototype of the ION G13, we broke new ground. Soon the concerns turned into pure enthusiasm. The ION G13 can do more than you might think at first glance – uphill as well as downhill. Basically the ION G13 is a trail bike with which you can heat over your home trails and enjoy long trail tours… but there’s more. Thanks to its progressive GEOLUTION geometry, the ION G13 takes you uphill even when other bikes are already at their limits. And downhill you take even the steepest passages with a subjective safety like you have never experienced before. The Ion G13 is a bike with an incredibly wide range of use – from the classic tour to the aggressive all-mountain. The ION G13 is the bike we want to ride every day on our own trails.

Rock Shox Monarch RT3 DB

Good damping must not fail even on rocky terrain and after steep descents.

With its butter-soft suspension travel and new lightweight design, the Monarch now floats even better over uneven terrain and transforms rugged terrain into a board track for perfect traction. Despite its slim design, the frame offers the necessary resilience and adjustability to effortlessly master hellish terrain and enormous cross-country stretches.

RockShox Pike RCT3 140mm


The completely redesigned Pike is completely black for a good reason. This suspension fork heralds a new era in damping performance. It is by no means a trail suspension fork like any other. In her case, all traditional production processes were thrown overboard. The result: The Pike is like a camouflage bomber and was specially designed for trail riders of the new generation. Their damping has a large and extremely soft spring travel. The asymmetrical design of the frame sets new standards in the industry and provides an unbeatable ratio between stiffness, travel and weight, which other manufacturers will probably work on for years to come. But more important for you is that you have a decisive advantage over other drivers.

DT Swiss EX 1501 30mm 29"

Unsurpassed weight to strength ratio.

The Enduro version of the SPLINE® ONE line is available with 30 mm rim width. The larger internal width increases the tyre volume with the same tyre width, which improves traction and comfort. The specifically developed surface hardening process allows an unsurpassed ratio of weight to strength and makes the EX 1501 SPLINE® ONE the perfect enduro wheel.

X01 Eagle Boost 170mm

More stable - stiffer - lighter

The X01 Eagle™ crankset was developed for winner types. It is completely revised. With the special CARBON TUNED™ laminate technology. The X01 Eagle™ crank is tough when you’re chasing over rough and tumble on the ideal line. The X01 Eagle™ is the strongest, stiffest and lightest crank on the market. With its new Eagle™ Direct Mount chainrings, it is perfect for taking the podium. Providing you want it.

Sram X01 Eagle

The next level.

The new Eagle™ rear derailleur not only has a larger capacity; it is also the next stage of the proven X-HORIZON™ technology specially developed for 1x circuits. The larger, lower X-SYNC™ shifting roller with 14 teeth ensures sufficient capacity to handle the cassette with sprockets from 10 to 50 teeth. The design of the rear derailleur is nevertheless compact. It also ensures that you always pedal evenly. Its torque curve is even smoother thanks to the new Type-3 ROLLER BEARING CLUTCH™, so that shifting is quieter and “rounder”.

Magura MT5

German Engineering for maximum safety.

Proven 4-piston technology from motorcycle racing, adapted for bike use promises maximum braking power. Braking power combined with ergonomics results in a performance package with which you can confidently tackle any trail, any difficult terrain with infinite serenity. The aluminium brake levers are ergonomically located on the hand and allow easy and precise control of the braking power even during long braking processes. The use of Carbotecture® technology in the brake handle housing helps the MT5 to light weight with top braking performance.
