Using our renowned Racelight geometry, the kinesis 4S offers a true race geometry but with the ability to fit full length mudguards and a pannier rack.
The Kinesis 4S is for the rider looking for a Winter bike that will handle like their Summer race bike, or a Winter bike that they can race through the Summer. A true four seasons bike.
The Kinesis 4S is the natural evolution of our very first Winter training frames, however the Kinesis 4S should not be consigned to Winter riding only. We have put everything we have learned during the last 17 years of geometry, and alloy frame design and manufacture into the Kinesis 4S . Whilst other manufacturers focus has been on carbon, we believe that by putting the same development into alloy tubing, we have created a frame that rivals carbon in many ways, and hands down beats it on price.
Damian Mason of Kinesis UK said ‘Kinesis are the only frame manufacturer to use Super Plastic Forming (SPF) on their alloy frames. Most manufacturers use Hydroformed tubes, but with SPF we can create lighter tubes and more intricate shapes that will build into a lighter and stiffer frameset.’
We have combined our SPF Kinesium aluminium frame with our renowned Tracer Disc Thru Axle full carbon monocoque fork. The Tracer Disc’s square crown provides the perfect space for mounting our Kinesis Fend Off full length mudguards. The Tracer Disc has great tyre clearance, internal routing, mudguard compatibility, discreet Shimano flat mount fitting, all in a lightweight package.
As with our premium titanium Kinesis GTD frameset, we have partnered with GW engineering and we are supplying the Kinesis 4S with their patented ‘Switch Lever’ hollow Thru Axles with a removeable lever.
The Kinesis 4S uses adaptable cable ports which allow you to build your frame with exactly the right cable routing for whether you are running Di2 or mechanical gearing with either a 1x or 2x set up.
The frame has twin bottle mounts on all sizes along with mudguard and rack mounts.
