Only Knolly Fourby4 suspension can achieve balance in all four of these categories with no compromise. We can build the bike to deliver the exact ride experience desired which means our bikes are some the best performance full suspension bikes on the market.



The rear triangle pivots determine the rear wheel axle path and the anti brake jack characteristics of the frame.  The chainstay pivot placement means the brakes do not lock up the suspension.

The linkage pivots are isolated from the rear wheel axle path and they are directly responsible for the progressive nature of the rear suspension. For more tech nerdy info on our Fourby4 check out our suspension page.

Fourby4 Suspension
Fourby4 Suspension

Yes, you see an extra linkage here. This is the secret sauce in the Fourby4 design. It allows us to decouple the performance aspects of the rear suspension, which means we can fine-tune each bike to match its intended purpose. Put simply - the lower linkage controls the rear wheel axle path, and the upper linkage controls the shock progression.

OSD Seat Tube
OSD Seat Tube

One of the great benefits of the Fourby4 system is that it allows our frames to have full length, straight seat tubes. That means whatever your rider height/seatpost length combination is - it will work on a Knolly. Our frames can handle a 150mm dropper (small) all the way up to a 200mm (large & Xlarge).

157TRAIL Rear Hub
157TRAIL Rear Hub

At Knolly our design philosophy demands that any performance feature change needs to be supported by a valid engineering position and proven rider performance benefits. 157TRAIL allows us to increase tire size compatibility, makes the rear triangle stiffer and keeps our chainstays short.

Threaded BB
Threaded BB

We use threaded BB’s on all our frames. Why? Well, because they don’t suck. We are all riders and we have all spent time on press fit BB’s and from our experience threaded is the only way to go. The interface between the BB and frame is serviceable, there is less chance of frame damage and threaded BB's will not creak when installed properly.

Angular Contact Bearings
Angular Contact Bearings

Our main pivots rotate on exceptionally high quality, dual row angular contact bearings, which are fastened with our custom oversized CNC’d axles. This combination results in superior lateral rigidity and high load carrying capability.  But what it really means is you spend more time riding your bike and less time fixing it.

Titanium Pivots
Titanium Pivots

We designed our own custom titanium pivot hardware because off-the-shelf options were not up to our standards. This hardware acts as a fastener, axle and bearing cover. These are CNC machined from bar-stock black titanium. There are cheaper and easier ways to design a pivot, but they do not fit with our no compromise philosophy.
