Tech of the week: new Shimano Dura-Ace, new bikes and more

The lead-up to the Tour de France is always a busy time for tech announcements and we've rounded up all the pre-Grand Depart tech news from last week

The big news this week came from Shimano. Its new Dura-Ace R9100 groupset includes not only updated components with lower weights, but new shifting logic and a new app to control it too. In addition, there’s a new power meter, Dura-Ace level disc brakes and new wheels including disc braked options.

New bikes from Cannondale, Lapierre and Wilier

We’ve also had news of Cannondale’s disc braked SuperSix Evo, which we’ve been test riding too in the Austrian Alps. Cannondale has also redesigned its SuperX and CAADX cyclocross bike ranges. Both have new geometry designed to increase stability and manoeuvrability on technical courses. The SuperX also has fully internal cabling and its bottom bracket shifted to the right for shorter chainstays and increased clearance.
