Direct mounting for single or double chainring configurations
This article originally appeared on BikeRadar.
US component brand e*thirteen was on hand at this year’s Interbike, to show us its latest cranksets as well as a Steve Peat inspired take on the long-standing LG1 chainguide.
The new TRSr cranks tip the scales at 510g for the arms, and 720g with a single, 34T chainring. They’re designed for use with single or double chainrings.
Chainring combinations for single-ring setups are 28, 30, 32 and 34, and the chainrings are designed to work with 10- and 11-speed drivetrains. However, unlike SRAM’s 11-speed chainring, the teeth aren’t designed to match up with the inner and outer plates of an 11-speed chain.
Double versions, CNC-machined from a single block of aluminum, will be available in November 2012 in 20/34, 22/36 and 24/38T combinations. Like the single rings, the doubles will mount directly to the crank arm – they’re secured via a lockring that employs the same proprietary interface used to install the company’s bottom brackets.
The TRSr single cranksets will retail for US$370. Doubles will go for US$400. Bottom brackets are not included.
Limited edition LG1
e*thirteen-sponsored racer Steve Peat has been putting the LG1 through its paces for some time now, and now the company has created a limited edition of the guide in his honor. Of the 500 produced, retailing at US$165, seven will feature Peaty’s signature.
Plastic chainguide bits will be offered in a number of color options
