2015 Cannondale Slice Black Inc triathlon bike

The all new Cannondale Slice triathlon bike will formally debut at Ironman World Championships Kona in October, but we’ve got a first look at the top model, the Slice Black Inc.

Goals were to reduce weight as much as possible, add aero efficiency and make it more comfortable. Compared to the outgoing model, they don’t have final wind tunnel data but they’re saying it’s significantly improved. That was done by making the frontal profile narrower, reshaping the fork legs, and smoothing the fork crown to downtube transition.

Those aero changes were the obvious ones. It’s the other little tweaks that make it unique -and UCI illegal- along with the impressive frame weight…

The cables all enter the top tube behind the steerer rather than from the side of the down- and top tubes like before.

They made the seatstays super thin – so thin that they’re not UCI legal. That not only reduced drag but also gave the bike a bit more compliance so you’ll fresher for the run.

Cannondale’s PR manager Bill Rudell told us many triathletes are running shorter crank arms these days, so that trend allowed them to lower the BB by spec’ing about a 5mm shorter crank arm depending on frame size. Lowering the BB puts the whole rider lower, which reduces total drag.

The trailing edge of the downtube was flattened to make it easier to mount a water bottle.

The yoke at the top of the seatstays has a relieved channel that helps move turbulent air off the top of the tire, which they say created a small amount of drag.

Frame weight was dropped down to about 1,000g, roughly 120g lighter than before. That’s very light for a full featured tri frame, and Cannondale says it’s the lightest one out there.

The Slice Black Inc model shown here will retail for $10,830. That gives you FSA aero chainrings on SiSL cranks, Vision deep section carbon wheels, Dura-Ace Di2 and FSA/Vision cockpit.  There’ll also be DA and Ultegra Di2 versions, plus Ultegra and 105 mechanical versions.

The sleeker, even more aero Slice RS introduced as a 2012 modelremains the absolute top model, but this new standard Slice puts it one step closer.


We saw most of Cannondale’s 2015 road bike lineup at Presscamp this summer, but they saved a few new ones for Eurobike to keep things interesting. Above, the CAAD10 alloy frame gets a “race” build spec’d to provide the biggest bang for the buck for crit racers. Money was prioritized for parts that make a performance difference, so it gets a SRAM Force group with FSA 52/36 chainrings on Cannondale’s SiSL cranks. FSA Energy wheels and Schwalbe One tires keep the rolling stock light and fast. Up top, they saved some coin by sticking with house brand alloy cockpit parts. Unfortunately, we won’t have pricing on this or any of the rest of the road models for a couple days.


The new CAAD10 Track 1 takes their top level alloy road bike and converts it to sliding dropouts and gives it a SRAM Omnium crankset, Mavic Ellipse wheels and Schwalbe Lugano wheels.


Not that you need it for track riding, but the frame keeps the SAVE comfort stays and carbon fork, so should you take it to the streets it’ll be a little less punishing.


The Synapse Carbon Hi Mod Red Disc is one of the top spec’d models for the line, getting a SRAM Red Hydro-RD group and Cannondale’s superlight one-piece double chainrings and new carbon C-Zero wheels.


Cannondale, like everyone else, is expanding their e-bike offerings. They’ll start in Europe, like almost everyone else.


Some incorporate a rigid Lefty fork, some get the Headshok. And some are just standard commuter bikes without the Bosch e-bike system.


As usual, they had a custom painted bike for Peter Sagan gracing the booth.







  1. Congratulations Cannondale for making the most disappointing $10,000 bike I’ve seen in a long time. non UCI legal seat stays and an exposed front brake? Who exactly are you trying to sell this to?

  2. Isn’t Peter Sagan switching to Specialized? Why are they still painting bikes for him? or is Cannondale going to sponsor Tinkoff Saxo…

  3. Thats Sagan’s bike from this years TdF. He will be riding Specialized next year unless Tinkoff changes bike sponsors. Garmin will be on Cannondales, with the name changing to Team Cannondale, with Garmin the secondary sponsor.

  4. Isacc – “Cannondale Slice triathlon bike will formally debut at Ironman World Championships” I think it’s pretty clear who their target audience is.

  5. It blows my mind that Cannondale would show an aero bike built like that. The R&D goes crazy for the cleanest, smoothest lines and the mechanic blows it with messy di2 wires and a wildley long front brake housing. The front end of this bike could look so stremlined, and instead it looks like a birds nest

  6. The CAAD10 track frame is rather pretty. Keeping the C’dale green (even though they look best in volvo/c’dale blue) without being garish. Now if only they would make an updated prophet…

  7. Completely agree with Jeff. I was getting excited about the new Slice until I saw the mess of wires. Total lack of effort or lack of options on Cannondale’s part. Other companies, big and small, are designing systems that clean up this kind of mess. How in the world could they think that this is acceptable?

  8. Id like to make a couple comments about the Slice. Firstly being a mechanic for a pro triathlete i can say most know nothing about their bikes except how to pedal it. this athletes (swanky) bike has hidden brakes front and rear which require a min of 30 mins to switch pads and adjust the brakes when going from race wheels to training wheels in back. Most triathletes also fly their bikes more often then most roadies, sometimes wo someone to put it back together for them so having a simple front end makes it much easier for them to get it right.
    Ill admit cannondale should have done a better job of presentation of the cables but to be honest. who cares. most triathletes adorn their bikes with so many bottles and feed bags and general clutter a few wires isnt hurt that bad. Tri bikes when in use arent that aero. they have to much crap on them, the aero-ness of the frame is only to counter the un aero ness of all the crap the athletes put on there.

  9. Well said gabby! I couldn’t agree more. I’ve seen this bike in the flesh and it is way sexier and more thought out than a shiv or a P3/P5.

    It’s designed for riders not for a marketing team.

  10. Agree with Gabby. The people whining about the front brake and cables have probably never wrenched in a race environment. Also the amount of drag from an exposed cable is completely negligible. Even an exposed front brake creates very little drag. Keep in mind bikes get raced on the open road, not the wind tunnel. At the end of the day all these “aero” advancements really haven’t made guys much faster despite what the manufacturers claim. Want to argue this point with me? Fine, if you think aero doodads are the huge improvement the manufacturers claim they are then please explain why the average speed of the Tour de France has barely changed in the past 30 years (and keep in mind that in the past the Tour was quite a bit longer than it is these days!) Despite riding steel bikes weighing 20+ pounds with box rim/32 spoke wheels and only 5-6 gears manually shifted gears in back the guys in the early 80’s were only about 1 MPH slower than the riders of today (and again, the guys these days are racing a much shorter course)

  11. @Chris the reason the times haven’t changed drastically is because the TdF rides as a Peleton with attacks. They don’t sprint entire stages. If anything is to blame other than strategy the equal speeds is because of radios and power meters. Gone are the days where a breakaway can be sustained and catch the peleton off guard in a Grand Tour.

  12. Is there not a center pull front brake that works well ( Omega ?) and would clean up the front cable area. If so @ 10.6 K why is it not there.
    Us Age group short & medium length tri riders use little to no junk on our bikes.

    For us older age groupers travel set up is important. Though compliance is nice
    I dread adjusting rear lower brakes. though I seldom use my rear brakes I also seldom
    need compliance on a tri course. Though I love my Hi MOD Evo & have beaten a few
    tri bikes during hilly sprints while enjoying the cushy ride.
    Would perfer upper brakes to compliance

    Lastly I love my DI2 shifters on my aero bars. I think they belong on tri bikes.

    Thank you Cannondale in updating the Slice. & thank you Louis Garneau, QR, any all others that have done the same. We have some great choices in 2015
