A suspension system directed for mountain bikes and
especially freeride or trail bikes.


Despite that this is a full floating system it also
combines some of the advantages of the cantilever
designs & URT as well




After having contacted several manufacturers, it became necessary to construct a prototype.
For this prototype we moved the secondary suspension arm's pivot (the one that connects this part to the main frame) lower so the pivot, the bottom bracket and the rear wheel's axle are aligned. This was a necessary upgrade from the original design after the suggestion from Raleigh's R & D Dept. that this system will biopace all the time! (We don't agree. Turner's Maverick that has a similar 45-degree link at the bottom bracket, without creating any biopacing effects). So, Raleigh is wrong (the prototype proves this).

The prototype has demonstrated exactly what the patent theory claims:

A) The rear suspension's travel is 18 to 20cm and operates bob-free in all situations.
B) The full-floating shock delivers extremely smooth action with an increasing rate of compression.
C) This system offers increased traction of the rear wheel, without bobing or stiffening the rear end to the point of loosing the advantage of the suspension system (despite the high pivot of the suspension arm).
D) It offers a very stable landing.
E) Depending on the riding position (standing or seated)
  The suspension stiffens, without getting locked.
F) The suspension stiffens according to acceleration effort, thus saving energy.
G) Moving backwards & forwards on the bike affects the fork's caster, making the bike more stable at high speeds of descent and more easy to maneuver in steep climbs (actually the rear end pushes the frame upwards and forward).
H) The bottom bracket can be placed lower than normally as it subtracts slightly when the suspension is compressed.


Considering that this is our first prototype (not a pre-production model) and despite the increased weight (18 kilos) we could develop a trail bike with 145 / 150 mm front travel, 200 rear travel within the range of 12 to 13 kilos! The bike is equipped with the following:

A) Carbon fibre / kevlar frame & suspension arm, with fortal alluminum CNC parts. Ertalon bushings (easy to access for service).
B) Manitou X-VERT DC dual crown fork, 120mm travel.
C) Fox float R (no locking) 165mm eye-to-eye.
D) Shimano XT crankset, aftermarket inner ring, 20-32-44 T.
E) Time attack alluminum pedals.
F) Shram 9.0. SL 11-32 cassette.
G) Shram 9.0. shifters.

  H) Ultegra 68mm, 115 bottom bracket.
I) Shimano XTR front & rear derailleurs.
J) Shimano XT disc brakes.
K) Sacs chain.
L) American classic disc hubs.
M) Mavic 317 disc brake rims.
N) Ritchey logic ahead set.
O) Titec stem.
P) CM riser handlebar
A. Roox 30,8 430mm seatpost.
B. Selle italia transalp ti saddle.
C. Michelin wildgripper XL tires.

Despite its increased weight, this bike is able to climb steep ascents with ease. It turns steadily at high speeds and it is very predictable. At low speeds, despite its phenomenal high bottom bracket, it can clear obstacles in technical sections very easily. Have in mind that the frame geometry appears steeper, with a high bottom bracket when unloaded. With the proper sag (front & rear) the bike is in proper geometry.
