Tech of the Week: new Shimano Dura-Ace spotted, Team GB’s custom shoes, and more

Our pick of the biggest tech stories from the last seven days

New Shimano Dura-Ace spotted

Despite there still not being any official word from Shimano about the new Dura-Ace groupset, a video posted online (which was later deleted) gave us our best look yet at the 2017 model.

The most obvious change is the crankset, which has been beefed up considerably, although there have also been significant alterations to the shifter and rear derailleurs, both of which have been slimmed down, presumably in order to save weight.

Unreleased Bianchi ridden at the Tour de Suisse

Lots of new brands have launched new bikes in the last few weeks, with new endurance bikes from Canyon and Focus, a new range from BMC, and a whole new genre from 3T. However, Bianchi has done things a bit differently, testing its new bike at the Tour de Suisse before revealing any details to the public.

What we do know is its name, the Bianchi Oltre XR4, and that it uses Bianchi’s Countervail technology, which the company claims “cancels vibration while increasing the stiffness and strength of the entire frame”, improving control and reducing muscle fatigue. Beyond that, the difference from the old Oltre are subtle.

Team GB’s custom carbon shoes

So, you think your carbon-soled cycling shoes are flash? Well how about a pair of shoes made entirely from carbon-fibre? That’s what Team GB’s track cyclists will be using as they go in search of gold at the Rio Olympics.

The shoes are made by Simmons Racing, a US-based sports shoes specialist, which creates custom-moulded shoes that will give a perfect fit for faultless power transfer and, presumably, excellent aerodynamic too seeing as the single Sidi buckle is tucked away on the sole.

Viviani’s custom skinsuits


The other piece of custom Olympic kit that we got a peek at this week was Elia Viviani’s custom Castelli skinsuit.

Or should I say skinsuits. That’s because Castelli has produced multiple different skinsuits, each of which has been optimised for the different Omnium events as the Italian goes for gold in the multi-discipline competition.

What’s it like to go electric?

Slowly, slowly, electric bikes are beginning to gain a bit of a foothold in the UK. They’ve been popular for commuting and getting around town on the Continent for years, but for some reason we seem to have been lagging behind.

We headed to the Olympic Park to ride an electric bike for the very first time, which was an eye-opening experience to say the least. Watch the video above to see how we got on.

Fabric’s extensive new range

The Fabric name may only be a few years old, but the Somerset-based brand already has a pretty large portfolio of different products, and is looking to grow further going into the second half of 2016.

The most impressive-looking new product in the company’s range is this innovative light that can be used as either a front or back light, and there is also a new range of pumps and more saddles, tools, and water bottles to choose from.
