Tech of the week: aerodynamics, Spesh news, folding e-bikes and more

This is what we’ve got excited about here at Cycling Weekly in the week leading up to Easter.


We’ve been looking at all things aero over the last week. We’ve had a detailed discussion of how to balance up the need to be aero with the best position for optimum power delivery – a really flat-backed position might not be your most efficient for turning the pedals. Also last week, the 3cm rule for elbow position in time trials was summarily axed by Cycling Time Trials, so you can now get an even better aero position on your TT bike.

Wider tyres are great for winter riding, but keep an eye on wear and tear

Not all tyres are created aerodynamically equal

Your tyre choice too can affect your aerodynamics, and we’ve investigated the factors which make a tyre more aerodynamically efficient with leading experts.

And we’ve asked whether you are better off climbing out of the saddle, or if riding seated helps by keeping your wind resistance lower.

The Bianchi Oltre XR3 benefits from the Countervail tech found in the XR4

Bianchi’s Oltre XR4 is its top, pro-level aero bike raced by Lotto NL-Jumbo. It’s now been joined by the new Oltre XR3. We’ve taken a look at the new bike’s features and specs and will have more details to tell you next week.

Discs, tyres, folders and more

According to Specialized’s founder, Mike Sinyard, disc brakes are the future and all road bikes will be equipped with them. Spesh made a move to discs with its new Roubaix, which was announced as being disc only. But in his last few races, Tom Boonen’s Roubaix has sprouted rim brakes instead, as has Peter Sagan's, so maybe even Specialized isn’t so sure.

In the future, all road bikes will come with disc brakes - except Boonen and Sagan's

Spesh also launched new ultra-supple Hell of the North tubular tyres and a wider 28mm version of its S-Works Turbo Cotton tyre on the morning of Paris-Roubaix. And it took responsibility for the crash that took Nikki Terpstra out of the race when a pre-production rigid stem cartridge fractured.

And we also reported on a possible mega-takeover in the bike industry of the parent company of Raleigh and Lapierre by the parent of Cervélo and Focus.

Also last week, we took a look at folding bikes, their benefits and our pick of the crop. We’ve included a peek at folding e-bikes – an emerging trend.

We’ve also told you how to clean your bike in seven minutes, given you our pick of sub-£1500 road bikes, looked out some great deals on wheels, found some bargains from Wiggle as well as kit from other vendors in Sunday Trading. And if you’re off to a training camp this spring, we’ve given you five tips to get the most from your trip to the sun.
