Practical magnetic levitating transmission gear system loses its teeth

By - December 1, 2014 1 Picture
A new transmission device that uses magnetic levitation to almost completely eliminate friction and wear has been developed as part of the MAGDRIVE research project, a collaboration of seven European nations we looked at back in 2010. The creation of the unit entailed the development of a magnetic gear reducer and corresponding frictionless magnetic axles. Aimed primarily for use in spacecraft due to its extended mechanical life, the system is also adaptable for use in automobiles, railways, and aircraft. Read More

Nuseti mountain bike features a sealed drivetrain

By - July 10, 2014 8 Pictures
Much as mountain bike technology has advanced since the days of friction shifting and elastomer shocks, most MTBs are still equipped with dangling, fragile rear derailleurs and dirty chains. Switching to a belt drive or a hub transmission are a couple of options, but Polish mountain biking medalist Gregory Zielinski has created another. His Nuseti bike features what he calls the Inner Drive System (IDS) – a 16-speed planetary gearbox that's incorporated into the bottom bracket, and a chain that's enclosed within the frame. Read More

Synchrobox takes the guesswork out of shifting bicycle gears

By - May 7, 2014 3 Pictures
Judging by the increasing popularity of 1x11 drivetrains and hub transmissions, a lot of cyclists are evidently getting tired of shifting between multiple chainrings. Indeed, it can get confusing trying to figure out if your gearing needs are best met by shifting to a bigger ring in front, a smaller sprocket in back, or what. IXOW's new Synchrobox is designed to address that conundrum – it uses one shifter to automatically adjust both derailleurs, in order to attain the rider's desired gear ratio. Read More

Cavalerie brings belt drive to full-suspension mountain bikes

By - April 3, 2014 10 Pictures
Dirty, noisy chains and dirty, fragile rear derailleurs are two features of modern mountain bikes that could certainly stand to be made obsolete. Well, the Cavalerie line of full-suspension MTBs does away with both, replacing them with a Gates Carbon belt drive and an Effigear gearbox. Launched last year in its native France, Cavalerie is about to get a boost in profile, as it commences distribution in North America. Read More

Artemis unveils pCell technology promising high-speed mobile connectivity for all

By - March 12, 2014 5 Pictures
The rise of smartphones and subsequent explosion in mobile data usage has put a strain on mobile networks, slowing them down when congested and requiring more and more radio spectrum space to accommodate the demand. Artemis Networks hopes to solve this problem with a new technology called pCell, which promises full speed mobile data regardless of the number of users. Read More
