Tech of the Week: Shimano’s power meter, Rotor’s hydraulic groupset, and more

The biggest tech stories from the last seven days

Shimano leaks and revelations

After we reviewed SRAM Red eTap last week, this week has been the time for Shimano fans to look ahead to what might be coming out of Japan over the next few years.

That little black box looks suspiciously like a power meter to us

Having heard that FDJ had a few Shimano mechanics in tow while at a training camp a couple of weeks ago, we headed straight to the French team’s bus at the Challenge Mallorca to have a poke around in search of anything new. And what a treat we got, when we spotted what looks like a Shimano power meter attached to the bikes of Matthieu Ladagnous and Odd Christian Eiking.

When asked about the new boxes FDJ riders and mechanics refused to comment. One mechanic staunchly replied “no one will tell you what it is, you will find out in a couple of months”.

At the same time, our man in the Far East was sitting down with Shimano company bosses to discuss what they might have up their sleeves in the coming years. Perhaps unsurprisingly, a power meter was one of the things they mentioned, as well as creating an electronic version of Shimano 105 and a women-specific groupset.

Shimano won’t be going wireless any time soon

However one thing that we’re apparently not going to see any time soon is a wireless Shimano groupset. But that’s not because the Japanese company can’t produce one, but instead says that there is no demand for it.

Finally we saw a Shimano patent that suggested that it might be working on a hub design that would run completely silently when freewheeling. Unfortunately it’s pretty complicated stuff, so you’ll have to head over to article for a full explanation.

Rotor Uno hydraulic groupset receives race debut

Rotor Uno finally looks as though it’s race-ready

With all the rumours coming out of Shimano, the race debut of Rotor’s new hydraulic groupset sort of flew under the radar. Rotor Uno was announced at Eurobike last year, and has been ridden in training by Dimension Data before now, but finally received its race debut at Challenge Mallorca last week.

The groupset is the first to feature both hydraulic gears and brakes, with the levers and hoses being compatible with either rim or disc brake calipers, and we’ll keep an eye out to see if Dimension Data use it in more high profile races as the season progresses.

Fake bars vs guns of steel

If you’re thinking about picking up some bargain carbon bars through a dodgy online site, then watch this video first, where an admittedly rather ripped mechanic snaps a pair of fake carbon handlebars with his bare hands.

According to Mattias Lundin, the man who filmed the video, the bars were bought online for €30 and designed to look like a pair of Zipp carbon bars. He then repeated the experiment with the genuine product, which could not be broken.

More delays for Limits backers

This week also saw more bad news for the thousands of people who had put their money behind the Limits power meter. Completion of the crowdfunded project was initiall predicted for December, but the company has been plagued by delays, and now doesn’t expect to be able to deliver products to power meters until February or March.

Limits backers will have to be patient for a little longer

Speaking to Cycling Weekly, Limits marketing manager Ioanna Kontoliou said that the delays were “normal and no different from anyone else doing a similar project. We are as keen as any backer to see the product ship but we will not do so until we are 100% satisfied that the finished product will be fit for purpose.”
