Tannus Airless Tires claims flat-free riding without the drawbacks

Flat tires suck. You know it, I know it. Puncture-free, non-pneumatic tires have been around a while, but the trade-offs are hard to live with. However, Tannus Airless Tires claims its new Slick tire nullifies the downfalls by offering low weight, less rolling resistance and a comparable ride feel to its air-filled counterparts.

UCI to reveal new mechanical doping strategy on Wednesday

UCI mechanical doping tablet

The UCI will reveal its news strategy to fight and deter mechanical doping at a special presentation in Geneva on Wednesday. Cyclingnews will attend the presentation and have full coverage of the announcements. UCI president David Lappartient has said that the world governing body "doesn't want technological fraud to continue as a hot topic." "There hasn't been a lot of trust in the UCI's strategy, and that generated suspicions. With tighter, more efficient controls we can protect the riders and their image," Lappartient told La Gazzetta dello Sport i n December. Belgian rider Femke Van Driessche remains the only cyclist to have been caught with a motor at a professional race. The device was found in her spare bike at the 2016 UCI Cyclo-cross World Championships and despite protesting her innocence, she was handed a six-year ban . Since then, there have been several incidents at the amateur level including ...

Cycliq Fly12 CE light/camera review

Pete Muir Tuesday, March 20, 2018 - 13:06 Smart, intuitive device for both fun and safety 4.5 / 5 £270 With any modern piece of technology, one of the first tests of its quality has to be: can you make it work straight out of the box without reading the instructions? The Cycliq Fly12 CE combined light and camera very nearly passes this test. Nearly . It is a neat black box, measuring 84x55x30mm, that contains both a 600 lumen front light and a 1080p resolution video camera, and on its side are two buttons. Press the one with the ‘power’ symbol on it, and to a cacophony of beeping the main light comes on, and a little green LED on the side starts blinking to indicate that the video camera is working. What could be simpler? Image 3 of 7 Image 3 of 7 However, a glance at the ...

A sheath for the spinning knife: Shimano patents disc brake cover

A sheath for the spinning knife: Shimano patents disc brake cover

Shimano has been working on a cover to shield the rotors of its hydraulic disc brakes. The design , which was filed for a US patent in June 2017, shows a vented structure that covers a majority of the disc rotor’s surface and backs up neatly against one of Shimano’s own flat-mount disc brake calipers. It looks to have been designed to fit a thru-axle fork. It's official: disc brake guards are happening Could disc brake guards be the solution (to a problem that may not exist)? High-profile incidents involving injuries allegedly caused by disc rotors have previously sparked safety concerns in professional competition. Some riders referred to discs as "spinning knives" . Since then, a generation of disc rotors with chamfered (blunt) edges has been introduced. SRAM already produces chamfered discs, while Shimano has promised them on new R9100 series groups . We’ve also seen similar disc brake covers ...

French amateur mechanical doper sentenced to 60 hours of community service

French police seized the hidden motor and frame used for mechanical doping

Cyril Fontayne, the 43-year-old French amateur cyclist who was caught using a hidden motor during a race last October, has been found guilty of attempted fraud and sentenced to 60 hours of community service by a court in Périgueux. Fontayne was already found guilty of technological fraud and handed a five-year ban by the French Cycling Federation (FFC) in December, and AFP has reported that he pleaded also guilty before the correctional tribunal in Périguex on Tuesday. As well the 60 hours of community service, Fontayne must pay a symbolic €1 in damages to the FFC and a further €88 to the Créon-d'Armagnac cycling club, the organiser of a race in which he used his hidden motor. The former rider Christophe Bassons, who now works for the French Anti-Doping Agency (AFLD), was involved in unmasking Fontayne when he drove after the rider and blocked his escape when the motor was ...

First Look: Specialized S-Works Tarmac SL6 disc

Peter Stuart Wednesday, March 14, 2018 - 04:58 The already race-proven Tarmac SL6 has a set of disc brakes clamped on, and comes with Specialized’s brand new S-Works Power Meter Specialized has today released a disc version of the flagship S-Works Tarmac SL6, which comes complete with Specialized's new crank-based S-Works power meter. At a weight of 6.65kgs is on par with the very lightest disc-brake equipped bikes on the market. Specialized has been a champion of the disc brake on road bikes from the outset, with the Venge VIAS series now available only with disc brakes bolted on, so this release has been long expected – especially given the popularity of the SL5 generation Tarmac disc. The new Tarmac disc has already made an appearance at some smaller spring races by Specialized-sponsored teams. There’s every chance it may appear at the larger Spring Classics in place of the Roubaix ...

Questions SRAM won’t answer

SRAM has aggressively introduced a number of new technologies, being first to market with road hydraulics and a 12-speed mountain-bike group.

New Interbike podcast touches on e-bike research, retail growth, battery changes

Bicycle Retailer's Doug McClellan joins retailer Jim Strang and Raleigh Electric's Rob Kaplan participate in the latest podcast. LAGUNA HILLS, Calif. (BRAIN) — A new survey of 1,800 e-bike owners done by Portland State University and the University of Tennessee found that that most e-bike owners are very satisfied and really like their e-bikes (96 percent), because they are "fun" and "exciting" to ride. Most also said that they feel a lot safer on an e-bike than they do on a conventional bike, and they ride a lot farther and a lot more often than they used to ride a conventional bike. Bicycle Retailer's Doug McClellan wrote about the survey findings for the magazine's upcoming March 15 issue, and he's interviewed for Interbike – The Podcast's second episode. He also talks about how bike shares in many U.S. cities are investing in e-bikes to add to their fleets. Retailer Jim ...
