TECHNOLOGY
Our engineering team will not let us use any fancy acronyms, technical abbreviations or marketing jargon here. We are simply implementing some solid and well understood engineering principles to create the best performing trail bike possible! We are not re-writing the engineering text book here - just following it with some ingenuity.
High Pivot Point
Every rear suspension system has a pivot point. The suspension design on the Highlander uses a high single pivot point which results in a rearward axle path allowing the rear wheel to move with the impact, while the bike continues to maintain forward momentum. It is a sensation that you will notice from your first ride and the result is that the Highlander has an ability to negotiate chunky terrain with a speed and confidence that plenty of bikes packing much more rear wheel travel can’t match. The careful idler placement, mean the suspension performance on the Highlander is the best of all possible worlds. This is because the idler location controls anti-squat, creating a deliberate +100% anti-squat curve which eliminates pedal induced suspension bob.
Suspension Kinematics
The unique kinematics of a high pivot point design, with it’s rearward axle path and high anti-rise means that under heavy braking chassis stability and the geometry are maintained - this simply means that aggressive riding is rewarded. The sensation of “the bike not holding you back” is very real on the Highlander and you’ll find yourself hitting lines that you’d have previously reserved for your downhill bike (or imagination).
Linkage
Our linkage is designed to offer a progressive leverage curve intended to offer support for harder and more aggressive riders. The progressive linkage means that high volume air shocks and coil shocks are compatible. The use of an idler means that the leverage ratio of the Highlander is tuned independently of anti-squat and pedal kickback (of which there is a negligible amount).
Idler
In order to control pedal kickback and anti-squat on a high pivot point bike we need to use an idler. Unlike non-idler equipped designs we can virtually eliminate pedal kickback while creating a balanced anti-squat curve which is controlled by the idler position. In the real world this means the bike pedals incredibly well, without bobbing, while the suspension remains active providing traction. The lack of pedal kickback is instantly noticeable with the Highlander showing an uncanny ability to pedal smoothly through rough terrain.

SIZING GUIDE
FAQ
How much sag should I run?
We suggest around 30% for most riders, but this should be experimented with.
Do I need to join chains?
No - a standard 126 link chain will work with even a 12 speed Shimano or Sram set-up.
What headset do I need?
ZS44/28.6 upper and a ZS56/40 lower headset cup
Can I mount a chainguide to The Highlander?
Yes, we have two lower ISCG-05 tabs which allow the use of a lower guide/bash. For example the e.thirteen LG1+ Lower Only Guide.
Can I fit 27.5” wheels to the Highlander?
We have not designed the Highlander to work with 27.5” or 27.5”+ wheels.
What fork would you recommend?
We suggest a 140-160mm fork with a 44mm offset. A 51mm offset is compatible and will lead to a slightly more lively steering feel.
What type of shock can I use?
The Highlander works with most coil or air shocks on the market and it is recommended that a mid-mid tune is used. We can’t guarantee that a specific shock will have clearance. The shocks available on our online store are all compatible. We are aware that Rock Shox Super Deluxe Air shocks DO NOT FIT.
What chainring size should I use?
Anything from 28t to 36t will work great depending on how steep your hills are!
Can I use an oval chainring?
It is technically possible to run an oval chainring - however, you need to have a crank set and chainring combination that can be “clocked” to account for the idler wheels timing. This process will require some experimentation and as such we cannot recommend to offer support on installation.
What is the maximum tyre width?
2.8” - however, it does depend somewhat on the tyre manufacture so please check your chosen tyre does not rub the frame when cornering.
What is in the box?
In the box along with the frameset we’ll also include a rear axle (with a non-compressible sheath fitted for transit). There will be a mech hanger and idler wheel installed on the frame as well as a seat collar. A Manual for the shock you have chosen will be included.
