Cannondale Unveils Groundbreaking SuperX Body


Carbon fiber is thought for its unimaginable stiffness and strength-to-weight ratio. The bicycle business leverages these properties to create essentially the most energy-efficient and light-weight machines attainable. Nevertheless, these properties additionally imply carbon bikes are usually unforgiving and harsh, particularly race bikes. Velocity trumps consolation. Or does it?

Cannondale launched the SuperX gravel race bike right this moment, and immediately, the photographs of body tubes made me assume, “WTF?” I’m accustomed to carbon flex-stay mountain bikes. These single-pivot, short-travel mountain bikes supposedly “articulate” the rear axle by flexing body tubes within the rear triangle. Sure, these bikes will be quick, however I’ve by no means actually felt that the frames offered that a lot compliance.

However one take a look at the body visuals for the SuperX revealed that Cannondale took the flex-stay paradigm to the intense. I’ve by no means seen body tubes smashed so flat within the title of defying materials properties. Possibly the model’s excessive efforts to coax carbon to bend will repay with enhanced vertical compliance to realize extra consolation and velocity.

Probably the most “WTF” visible is the one of many backside bracket junction. The seat tube is impossibly flat. I can not recall one other body of any materials with a seat tube this skinny.

This “let’s bend carbon” logic additionally seems within the flex zones within the high tube and rear triangle. These flex factors are supposed to coerce the rear triangle to rotate ahead to afford vertical give.

In the event you take a look at the place every flattened part is and picture the rear axle wanting to maneuver upward, you possibly can “see” the rotation if the body certainly bends on the flex factors. That’s Cannondale’s idea, anyway.

Different Cannondale Tremendous X Options

Better vertical compliance is a bonus, however racers received’t settle for it if it comes at the price of different attributes. Cannondale made comparable enhancements in different areas so as to add to the SuperX status.

Weight

Flexy or not, racers need their rigs to be mild. And Cannondale hit the bull’s-eye with the SuperX gravel bike; it claims {that a} 56cm painted top-end LAB71 body registers below 900 g, which is amazingly mild for a gravel bike body.

Cannondale additionally claims that its uber-spec SRAM RED XPLR AXS-equipped model weighs solely 16.3 kilos, with sealant, no bottle cages, and no pedals. Just one different gravel bike has bested this featherweight quantity that GearJunkie has examined, and that’s the comparably outfitted Specialised S-Works Crux.

The LAB71 SuperX body is 100 g lighter than the outgoing SuperSix Evo CX/SE frames and about 100 g lighter than different variations of the Cannondale SuperX.

Cannondale Tremendous X Body Geometry

Cannondale caught to its weapons on the geometry, roughly matching the outgoing SuperSix EVO and SE bikes. Usually, the SuperX leans extra towards highway bike on the road-to-gravel spectrum.

Comparatively slack head tube angles are mated to reasonable path figures. This makes the entrance extra controllable in slick situations whereas retaining agility.

The stack and attain are additionally reasonable, with the numbers slanting away from “progressive geometry” (longer attain/shorter stem) and extra towards highway bike geometry.

Tire Clearance

Tire alternative and air stress dominate chatter in the beginning line of most gravel occasions. Each massively have an effect on the bike’s efficiency and luxury. The pattern towards wider, higher-volume tires is robust, so having the body clearance to no less than have these choices is a critical consideration.

Cannondale gave the SuperX sufficient clearance for a 48mm tire within the rear and a 51mm within the entrance. This isn’t a considerable amount of clearance by right this moment’s requirements, particularly for extra adventure-oriented bikes. I might say it’s solely ample for race bikes. Cannondale delivers the SuperX with 40mm tires, which does go away room for some mud build-up.

Inside Routing on the Cannondale SuperX

It’s arduous to withstand, and Cannondale joined the fray; routing is absolutely inside, by way of the headset, on the SuperX, a lot to the dismay of many.

Nevertheless, the model took steps to make sure housing doesn’t rub tunnels into the carbon steerer tube. A triangular steerer tube affords extra room for housings and hoses, and an Aramid wrap protects it from abrasion.

Body Mounting Factors

Cannondale goals the SuperX at racing and, by its logic, strips the body right down to minimal attachment factors. There isn’t any fashionable inside storage compartment and no bag mounts apart from a considerably hidden high tube bento field mount.

Apart from that, you get the same old pair of water bottle cage mounts. That’s it.

Aesthetics

Cannondale graced the SuperX with a extra basic look. Most fashionable bike frames have a steeply sloped high tube. This design permits extra of the seat publish to increase out of the body, theoretically inducing extra seat publish flexion, enhancing consolation and management.

Since Cannondale engineered the flex to happen inside the body, it doesn’t rely as a lot on seat tube flexion. The horizontal high tube lends a extra basic look to the SuperX and makes shouldering it loads simpler for individuals who benefit from the heinous burn of cyclocross.

Closing Ideas: Cannondale SuperX

If Cannondale’s radically flattened body flex zones work, the SuperX could possibly be an unimaginable gravel bike, for racing or not. To have a featherweight, environment friendly carbon gravel bike that’s nonetheless snug can appear unattainable. The S-Works Crux got here closest (in my eyes) in attaining this dichotomy of traits, however possibly the SuperX can nudge into its territory.

The model gives three variations of the SuperX, so the potential magic journey is not only for the wealthiest. Sure, the high-zoot LAB71 lists at a shock-inducing $15,000, however the 3 has an approachable MSRP of $4,200.

Cannondale has a historical past of nonconformity, generally to nice success, generally to dismal failure. However no less than it persistently butts up in opposition to the established order. And when its “radical” strategy works, it’s labored splendidly.

I’ll diligently pursue a check pattern of the SuperX to see if the newest bizarre AF Cannondale strategy breaks the mould in a great way.
