Warning: Using a 68-tooth chainring on this bike could void your warranty! Cannondale has just unleashed its latest weapon in the battle against the clock—the all-new SuperSlice time trial bike. But here's where it gets controversial: while the brand boasts about its speed and aerodynamics, they're also drawing a line in the sand when it comes to chainring compatibility. And this is the part most people miss: the frame is only officially compatible with a max 64-tooth SRAM Red aero chainring, leaving those seeking an extra gear at their own risk.
This bold move comes as part of a larger trend in the time trial bike market, with brands like BMC, Aurum, and Colnago also unveiling new models. We first caught a glimpse of the SuperSlice at the Mallorca Challenge last month, alongside other unreleased TT bikes. Cannondale claims this is their fastest bike yet, with a 10-watt saving at 50kph compared to its predecessor – a game-changer for pro riders chasing every possible advantage.
The SuperSlice has undergone a complete transformation, with a brand new frame and fork designed after 'hundreds of hours' of CFD analysis and wind tunnel testing. The most noticeable change is the deeper front fork, but Cannondale insists it's just one piece of the puzzle. The result? A claimed 14% reduction in frameset drag, achieved by adding 60 grams to the frame for improved aerodynamics, while saving weight on the base bar.
But is this focus on aerodynamics at the expense of weight a wise trade-off? Cannondale seems to think so, especially for courses with climbs where higher speeds are crucial. They've also increased headtube and bottom bracket stiffness, boosted tire clearance to 32mm, and introduced a new integrated carbon base bar designed specifically for the frame.
The geometry remains largely the same, but with increased seat angle and tri bar pad stack and reach ranges for more adjustability. This could be a significant advantage for riders like Ben Healy, who's expected to shine at this year's Tour de France, particularly in the opening team time trial.
As for the controversial chainring issue, Cannondale recommends a 3.7mm clearance between chainrings and the frame. It's a bold stance that's sure to spark debate among riders and mechanics alike. So, what's your take? Is Cannondale's focus on aerodynamics and strict chainring compatibility a step in the right direction, or are they limiting rider options? Let us know in the comments.
With a frameset price of £6,995 / $6,999, the Cannondale Lab71 SuperSlice is a serious investment. But for those seeking the ultimate in time trial performance, it might just be worth the risk – 68-tooth chainring or not.
