n-1 DesignED For Low maintenance:
This CUSTOM design uses the benefits of carbon monocoque construction from one huge tool. The "Reach" (top tube) can be changed to suit your needs, from between 420 - 485mm by using tool sections to lengthen or shorten the frame. CUSTOM options allow you to adjust the head angle Anywhere from 65 to 70 degrees. Bottom bracket drop can also be custom made by changing the mounting plates.
Elevated chainstays allow the frame design to use continuous runs of uni-directional (UD) carbon from the axles to the head tube. Elevated chainstays also gives the frame large tyre clearance around the chainstays and chainring. The gearbox is suspended from this structure on some adjustable "swing plates" that also tension the belt.
At OLSEN Bicycles we believe in versatility so we have designed a do-it-all chassis that can change with you.
SEAT TUBE SIZE - OUT THE WINDOW:
Frame sizing has changed. MTBs were always sized on seat posts, however stack and reach are a much better method. With the invention of the dropper post this has be come more important. If you are tall in the torso then you need a longer reach. If you like to sit up a little then a taller stack and shorter reach is more important. The dropper post means that the seat tube length is less important as the seat post can be dailed in at your handlebars.
THE LONG AND SHORT:
By adjusting the Reach, and head-angle. I can create a geometry with 66 deg to suit Long Travel forks or 70 deg to suit Rigid forks.
BOTTOM BRACKET & GEARBOX DROP:
The "swing-plates" tension the belt, but they also sling the gearbox under the frame. This allows the carbon to be almost continuous from head-tube to dropouts. The swing-plates can also be swapped out to adjust the bottom bracket height.
LONG TRAVEL GEOMETRY:
With a 430mm chainstay, 65mm BB drop and 65 degree slack head angle, this frame can handle 140mm forks with 29er tyres or 150mm forks with 27.5" tyres. This makes the riding style aggressive and perfect for jumps, burms and table tops at Trail centres.
THE N-1 BIKE BUILDER
The N-1 has been designed around the benefits of having a dedicated Pinion and Gates CDX drive train. If you want to SINGLESPEED or run a DERAILLEUR, then choose the N-2.
The N-1 is long with a Reach of up to 475mm, ideal for running 140mm forks with 29" or 150mm with 27.5"+ Wheels.
Head angle: 66 degrees
Headset: SHIS ZS44/ZS56
Fork Max: 530mm / 150mm (27.5") 140mm (29")
Wheel sizes:27.5x3.0" or 29x2.4"
Chainstay length: 445mm (113T belt) or 435mm (111T belt)
Rear end: 142mm Maxle
Seatpost: 30.9 or 31.6mm
Bottle cages: 1
The rear brake runs externally along the underside of the top tube and down the rear seat stay. 1 bottle cage ensures the down tube is un-drilled, holding its impact strength.
This frame can also be built up with the following options:
Pinion P-Line 18 - 9 speed gearboxes
Pinion C-Line 12 - 6 speed gearboxes
