‘In November last year, New Motion Labs (NML) made waves when it announced its Link Drive dual engagement chain which is said to be more efficient and durable than a traditional roller chain. NML has continued the development and testing of that chain design and hopes to have a multi-gear/derailleur compatible version in the near future.
Not content with reinventing the chain, NML has been busy radically redesigning the sprocket and tooth design. The claimed benefit of the chain was its dual engagement technology and the associated efficiency and durability gains, NML has now designed a tooth profile which forces the same dual engagement action on a standard roller chain.
New Motion Labs is launching its Enduo Evolve sprocket design, in single-speed only at the moment, with the same claims of improved efficiency and durability compared to a standard sprocket design.
The sprocket is noticeably different to a traditional sprocket design with fewer and wider profiled teeth. These redesigned teeth are said to force the dual engagement action on a traditional roller chain and NML are claiming this results in a 1% efficiency gain compared to a Shimano sprocket at 400-900watts.’
