As lateral thinkers we often find ourselves on a different path to the rest simply by questioning the status quo.

However, our customers expect more from us, they expect that we think ahead. We have done this and found out things that at first, we simply could not believe. During the two years of experimentation with new and uncompromising geometry, we found that the GeoMetron shape, balance and rider space can make both beginners and professionals alike faster.

All “G” models have been completely redesigned including a new swingarm and BOOST dropouts which are lighter and stiffer. Likewise, the suspension response has been fine tuned with the use of quadruple sealed ball bearings. Sealed for the applause of the people taking the ION-G16 on wet and muddy winter rides. The proven NICOLAI shock lever has been pushed through many FEM strength calculations in order to reduce the weight while keeping the same rigidity. Although our 5-axis CNC machine now runs a little longer, as a reward it’s lighter.

EXT STORIA LOK

THE ADVANTAGE OF COIL SPRING SHOCK WITH THE LIGHTNESS OF AIR

The EXT Storia Lok was the first mountain bike coil shock to have a 2 way lock-out system, the Storia provides the best performance and comfort on uphills or transitions, without any bobbing. The LOK technology is different to any other lock-out systems as it has a completely independent valve to control the oil flow, it is possible to have firm lock-out and maximum grip when you need it to climb rocky uphills trails. Then when you want to ride down the hardest trails you have full grip but also a smoother and more comfortable shock. This equates to the most efficient lock-out system enabling you to transfer all your strength to the bike. The LOK system has a special blow-off valve, so if you forget switch before a downhill section you can ride it out. The Storia Lok is the lightest enduro mountain bike coil shock available, weighing in at only 635 grams including spring (196×57 version with a 325 lbs spring).

Built for function over fashion

It's a Geometron for a reason

The relationship between the wheels, head angle, offset and where the rider weights the wheels is all we need to worry about when it comes to great handling bikes. The relationship between the saddle, the cranks and the rear axle is all we need to worry about when it comes to great climbing bikes. These two things are separate and you won’t screw up the handling of the bike by having a steep seat angle (as long as you can drop the saddle out of the way!) and neither will you compromise the climbing ability of a bike by moving the front wheel further away or setting the steering at a slacker angle! Honestly, it really is that simple.

CHAIN STAY MUTATOR

Adjustability is key

Chain stay length is adjustable via the rearmost mutator, available in differing lengths (33mm, 41mm and 47mm). No need to worry about creaks or servicing issues as the inner and outer chain stay mutator shells are positively connected via a wedge-shaped rectangular structure within the rocker. Twisting is prevented via thoughtful design. The mutators aren’t a one trick pony, they also function as the bearing axis – we spec readily available and cheap 6001 2RS bearings.

7020-T6 ALUMINIUM

ALUMINIUM IS NOT ALUMINIUM!

We exclusively use 7020-T6 alloy (AlZn4,5Mg1) for our frames. Compared to our competitors, who mostly use aluminium 6061-T6, the tensile strength of 7020 compared to 6061 aluminium is about one third higher. The elasticity is about one fifth higher. These properties, coupled with high quality welding, result in a bicycle frame that is far superior to the average in terms of durability. In comparison to carbon, aluminium is much more robust and tough, so that bottom contact, falls or stone impacts cannot harm the structure.

TRAVEL CHANGE

155mm or 175mm?

The G16 shock absorber length can be adjusted via the ET KEY and thus the spring travel can be changed. The damper length/stroke can be changed from 216x63mm to 222x70mm. As a customer you can fully configure the performance of your frame.

ALWAYS RECOGNISABLE BY ITS WELDS

Our evenly flat scaled welds are produced by a very slow welding speed

The wide, flat shape of the seam ensures optimum force dissipation in the area of the weld. Welded in several passes by TIG (tungsten inert gas) in order to minimize distortion. Very large loads, such as those caused by jumping or braking, are absorbed by so-called “casting sets”, which are additionally welded onto the frame. For you as a customer, this creates a long-lasting product that can offer many years of fun even under the toughest conditions in racing.

ANGULAR CONTACT BEARINGS

4 WAY SEALED

The rear triangle of a full suspension bike is not a statically rigid component and is exposed to extreme loads during riding. We spec full complement, double-sealed ball bearings as they have a higher load rating than standard ball bearings, as a higher number of balls are used in these bearings – in summary, they are more robust. These are then further protected by two additional O-ring seals located on the pre-load caps. Thus, the bearings are optimally protected against moisture and dirt.

RADO

REAR ALIGNING DROPOUT

The right side dropout (gear hanger) allows us to reduce the rectification work on the frame which also means less stress on the material. The hanger is marked with the indices -1 -2 0 +1 +2 for different toe and camber adjustments.
