• mullet option thanks to flip chip on the shock mount
• internal cable routing
• extruded tube profiles
• replaceable dropouts to adjust the rear triangle length
• high-pivot design for rearward axle movement, resulting in less loss of speed during compression
• balanced modern geometry with relatively flat head tube angle and rather steep seat tube angle
• variable travel depending on the selected stroke
• with SRAM UDH universal derailleur hanger, therefore broad compatibility, also suitable for Eagle Transmission groupsets
• optimised for 44 mm fork offset
• with integrated seatpost clamp
• integrated bashguard
• headset minimum offset below 9 mm

Technology:

GEOLUTION
GEOLUTION is a geometry concept developed by Nicolai and Chris Porter. It is based on the knowledge that a longer wheelbase, a flatter head tube angle and a steeper seat tube angle make the bike faster, smoother, safer and better able to climb. The long reach, steep seat angle and long wheelbase puts you squarely in the centre of the bike with a sporty, relaxed riding position. This complicated subject can be broken down into 4 advantages, which offer both professionals and beginners a clear added value: unparalleled climbing ability (front does not climb), no roll-over feeling while riding downhill, an integrated sitting and standing position for the rider on the bike (more control), higher cornering speed (more grip on the front wheel).

7020-T6 aluminium
Not all aluminium is the same! Nicolai only uses a 7020-T6 (AlZn4.5Mg1) alloy for frames. Compared to 6061-T6 aluminium, this grade offers much better strength. The tensile strength of 7020 compared to 6061 aluminium is about one-third higher. The elastic limit is about one-fifth higher. These characteristics, combined with high-quality welding, result in a bicycle frame that is far superior in terms of durability. Compared to carbon, aluminium is much tougher, so that hitting, falling or stone chipping does not damage the structure.
