The LIGHTEST Rim Brake Cannondale SuperSix Ever?

The Cannondale Supersix is a dreamy climbing bike. But what if you used a robot to strip its paint and excess carbon?

Current men’s National Hill Climb Champion Andrew Feather did just that, before building it up with a host of exotic parts. This rim brake dream has to be one of the best hill climb builds of all time.

As time goes by, we might see bikes evolve by years, but you can always surely see cannondale Supersix shines every year!

1 year on the disc and hes back on the rim for the climbs!

5kgs! Pretty incredible. Always wondered how a bike this light would feel next to my 7.6kg one. That rim brake bike is a work of art really. Love the simplicity of the brakes, seat post, stem, and handlebars. All easily adjustable, fine tuned, or changed at home in a few minutes really. And also love the fact it doesn't look like all the other modern bikes with the drop seat stays etc. Those colourful anodised brakes are also another nice touch against the matt black frame.

As a rider of a 2012 supersix evo ultimate, its always good to see a traditional rim brake hill climb bike.

[samhamfast]

I ride a SuperSix Evo with disc brakes but I've got to say that I love this classic rim brake bike.

[FL-ymhm]

Love the Super Six. What a purpose built machine. Damn!!!

[sapiens]

Pure Roadies those in the know from the rim brake era Cannondale Supersix Evo Is what a bike should be, light, fast, agile, responsive, great in high winds. These are like hens teeth now.
Would love to see Cannondale make an anniversary rim brake edition.

[Ey_up]

More Jack Luke!
More niche steel bikes with rim brakes!
Thank you. 😊

[mediakk]

Great build Andrew, I reached the 4.995 kg with the same supersix Evo without removing the paint with gps mount and a single bottle cage. Please let me know if someone wants details. ❤

[SuperCanonshooter]

I have two caad 12’s because I love the frame design so much..really fun feeling ride too! But I’d love to have a lab71 just to experience that level of responsiveness

[filipsoltys]

5.080 wet. Reckon its sub 5 if you dried it off

Andrew Feather, notching another W for nominative determinism

[straightcirclee]

What a coincidence i just watched your winning bike with disc brakes in the Struggle national hill climb 2023..

[ScottCopeland-yhlm]

Great chat on Path Less Pedaled. Well done on your channel. I think you might have something here.

[timtaylor]

andrew rides a lot racking up koms all the time he uses this bike, for racing he has to use the disc for his sponsors. that says something

[PeakTorque]

Sorry what calc or software are the company using to measure wall thickness?! What you showed is a 3d scan of the outside

[kramrenrut]

I’ve a few pairs of those tubs rubbing my hands waiting for the hill climb eBay season

[wrcompositi]

I don't understand the logic of "parts bin build" on a heavily modified frame. Although a 600g modified SS evo frame is impressive, but a stock frame without paint is already as low as 700g. Instead of shaving carbon from the frame, there are apparently many low hanging fruits to reduce the weight of this bike. Lighter parts such as THM, Darimo, custom wheels, custom saddle-post one-piece combo...
Are flat bar bikes allowed in UK hill climb races? I've seen many nice sub-5kg bikes for these races, but not spotted any flat bar, which should save some more weight.

[JonFairhurst]

For the real world, I’d take the Lab 71. The lighter bike would be marginally better going up the hill, but the aero, disc, solid yet compliant bike would give me much more confidence on the way back down.

[pierrex]

Would be very curious to see testing between the two bikes. That lab 71 was stupid light already, so then maybe it indeed is faster because it's stiffer? But also that supersix rim was peak rim brake, so may have been plenty stiff? The tyres would have to the same ofc to mean anything.
But really, really cool build.
Fitting for a boy named feather, too.
