An all-new, fast, gravel frameset from Kinesis. The GX Race combines the speed and agility of our race winning CX Race frameset, with the strength and capability of our award winning Tripster AT frameset. With our new race inspired gravel geometry, you are more aerodynamic in the drops or the hoods of the GX Race. A longer reach allows for shorter stems to be used and better off-road handling at high speed. If your riding extends to swift bike packing trips, then you can still load this bike up to reach destinations faster. We have matched our GX Race premium alloy frame with the all-new Columbus Futura Cross Plus full carbon monocoque fork. The Futura Cross Plus features cargo mounts, internal dynamo cable routing, masses of tyre clearance and adjustable offset, all wrapped up in a lightweight package. The GX Race uses adaptable cable ports, allowing you to build your frame with exactly the right cable routing, whether you're running wireless, Di2 or mechanical 2x or 1x gearing. As with other framesets, Kinesis have partnered with GW Engineering and are supplying the GX Race frame with their patented ‘Switch Lever’ lightweight hollow thru axles with a removable lever. Features: Tough yet lightweight 6069 series tubeset with tapered machined headtube. All new colour matched Columbus Futura Plus carbon fork with 12mm Thru-Axle. Inboard Shimano Flat-Mount disc mounts on frame and fork (maximum 160mm rotors). Seat stay mounts for mudguards and pannier racks. Bridges on chain stay and seat stay for fender mounting, runs 40mm tyres with full mudguards for clean winter riding! 700c x 45mm tyre clearance / 650b x 50mm tyre clearance. 2 x bottle boss mounts with multi position points plus top tube mounts for secure fixing of a top tube bag. Headset, Thru-Axles, seat clamp and all cable guides included. Internal cable routing for mechanical and electronic gear systems. BSA threaded BB for real world low maintenance riding. Semi-sloping top tubes on our smallest sizes ensure a great fit without compromising handling.

‘AT’ stands for All Terrain. Our new gravel adventure bike frameset to do it all. The Kinesis Tripster AT frameset takes our years of experience gained from the now legendary Tripster ATR and our range of championship winning cyclocross bikes, to create a bike capable of almost all terrains and adventures for all seasons. During the development of the Kinesis Tripster AT we also worked closely with the late Mike Hall in the design process and gained from Mike’s knowledge and love of long distance, multi-terrain riding. The final production model features a number of enhancements thanks to Mike’s input and you can see this referenced on the frame graphics. The Tripster AT boasts cutting edge adventure bike features and versatility, allowing it to be built to excel across a variety of uses. Commute on it, ride bridleways and gravel with it, go bike packing on it, ride across continents on it. The new Tripster AT will take all of this in its stride and more. With through axles front and rear, clearance for 700c x 45mm or 650B x 52mm tyres and with cable routing for any kind of group set, this bike can be a two wheeled Swiss Army Knife! Add in multiple bottle cage mounting, rack and mudguard mounts and the dependability of a British Standard bottom bracket with Kinesis UK proven geometry and you have a recipe for adventure. The Tripster AT is such a capable and versatile bike that it might well be the one you ride the most of all. Features: Tough yet lightweight 7046 series Kinesium tubeset with tapered machined headtube. 31.8mm seat tube for 27.2mm seat post (will add a bit of compliancy). All new colour matched Columbus Futura Carbon fork with 12mm thru axle. Inboard Shimano Flat-mount disc mounts on frame and frame and fork (maximum 160mm rotors). Seat stay mounts for mudguards and pannier racks. Bridges on chain stay and seat stay for fender mounting, runs 40mm tyres with full mudguards for clean winter riding! Beyond gravel capability with 700c x 45mm tyre clearance with supplied fork and up to 52mm clearance on the frame. 3 x bottle boss mounts for extra carrying capacity or storing a tool keg. Optimum hydration system – multi position down-tube bottle cage mounting to allow for full bottle carry capacity even with a frame bag. GW Switch Lever Thru-axles included Internal cable routing for mechanical and electronic gear systems. BSA threaded BB for real world low maintenance riding.

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. Features: 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. Specifications: Super Plastic Formed Kinesium Aluminium Tracer Disc Thru Axle carbon monocoque fork 142x12mm Thru Axle rear spacing 100x12mm Thru Axle front spacing GW ‘Switch Lever’ axles front and rear Clearance for up to 30c tyres Clearance for up to 28c tyres with guards Di2 / 1x / 2x mechanical compatible Two bottle cage mounts Mudguard and rack mounts 68mm threaded BB 27.2mm seat post required Kinesis designed tapered headset with ACB bearings Colours: Shocking Pink or Royal Blue Sizes: 48 / 51 / 54 / 55.5 / 57 / 60 / 63 Warranty: 3 years Frame supplied with fork, headset, seat clamp, front & rear through axle, frame ports and cable guides.
