Ready to race uphill or down, the SuperSix is still a class act
Skip to view product specifications

We’re no strangers to the SuperSix, having tested various models over the years, from full pro spec to the more affordable SRAM Apex setup. The all-new Di2 model not only ups the specs to electronic shifting but also has excellent wheels in the form of Mavic’s Ksyrium Elites.

  • Highs: Responsive, fast ride with light wheelset
  • Lows: That high price tag
  • Buy if: You want a racer that will shine on climbs

The SuperSix frame has been around a while, but at 1,150g it’s still one of the lightest. It’s now been adapted for Di2 use with internal routing through the head tube, seat tube and stays. The battery is mounted using Shimano’s bottle cage boss fitting, which may look a little like an afterthought but is well placed and out of the elements. The front mech wire exit is forward facing, just above the BB30 bottom bracket shell – a simple route without much exposed wiring.

The SuperSix’s ride is always a treat to return to and this is as good as ever – it’s all about instant gratification. It accelerates under power with ultimate willing, the steering response is sharp, swift direction changes are made with ease and it inspires confidence everywhere. 

For a frame that makes no concession to comfort, it’s very well mannered over rougher surfaces, giving you feedback on the road surface without getting wearing – freeing you up to explore levels of grip from Schwalbe’s excellent Durano S tyres.

Hit the hills and the SuperSix’s other upgrade – the lighter wheel package – comes to the fore. We’ve often stated that this frameset would enjoy better wheels. Well, this version has delivered. Add in FSA’s SL-K compact chainset and it’ll conquer any climb.

The well-shaped compact drop bar and high-quality Arione saddle contribute to a bike that’s ideally suited to the rigours of racing and big-mile rides, and they keep the overall weight down too. Combine this with the performance of the Ultegra Di2 and you’ve got one superior bike. 


Any downsides? Well, there’s the hefty price. It’s more expensive than similarly (or better) specced electric shifting bikes, so doesn’t come with as much bang for your buck.
