Interbike 2015 – e*thirteen TRS+ Cassette, LG1r Carbon Chain Guide and LG1r/TRSr Carbon Cranks

TRS+ Cassette

The Hive’s e*thirteen group is coming out with the highly innovative TRS+ cassette that is an 11-speed 9-44T extended range cluster. They also have an upgraded LG1r Carbon Chainguide and the trick LG1r and TRSr carbon cranks.

TRS+ Cassette

Although the 1×11 drivetrain system works incredibly well and is simple and light, it still doesn’t have the gear range of any 2x or 3x system. E-thirteen has resolved this to a degree by offering an 11-speed 9-44T cassette that has a monstrous gear spread that’s close to most 2x systems. This multi-piece system fits on the SRAM XD driver body and weighs a respectable 320 grams.

The new TRS+ cassette is an ER (extended range) system that offers a tiny 9-tooth inner cog on the high end and ramps up to a huge 44-tooth (11-speed) or 42-tooth (10-speed) on the low end. The system utilizes a one-piece aluminum cluster for the upper three cogs (two on the 9sp) and heat-treated steel on the lower eight cogs and is only available for the SRAM XD driver body. The steel cluster is the same between both the 10 and 11-speed cassettes though the back cluster changes. All alloy materials wear faster than steel, so the multi-piece design allows them to sell the aluminum cluster separately when needing replacement. Also, since the eight-cog steel cluster is the same for both the 10 and 11-speed, you can easily upgrade in the future by adding the appropriate aluminum section.

I am looking forward to trying the TRS+ cassette 11-speed 9-44T cassette out on my drivetrain. Most of us are running a 30 or 32T front, and the 44T rear is sort of nice for steep and slow climbs on a 29er. “For the use of us mortals” Also, the small 9-tooth in the rear will keep me from spinning out as earlier on flatter terrain and some downhills.

The aluminum cluster attaches onto the XD freehub body’s threads using a lock ring and then the steel cluster locks down onto the alloy section via hooked flanges using a chain whip.

LG1r and LG1+ Chainguides


LG1r and LG1+ Chainguides

The downhill oriented LG1+ and LG1r are lighter, stiffer, and now use a lower idler roller guide and have a long meaty bash guard, which comes with three included sizes. For this season, the upgraded LG1r gets a full carbon backplate that offers more energy absorption and strength. The bottom roller is removable for those days when riding on the milder terrain. The LG1+ weighs between 136g-167g and retails for $150. The beefy and thick EXA+ Aluminum backing plate now fits all chainring sizes from 28 to 38 teeth. Both chainguides come with three different spacers of varying thicknesses to help with fitting and chainline adjustments.


The new chainguides utilize an innovative tool-free “Easy Adjust” latch buckle design in which the upper guide swings up and away from the body for easy crank removal. The polycarbonate parts are now resistant to solvents than its predecessor, so dry lubes, and cleaners don’t cause issues. The lower roller and the interior of the upper slider have co-molded soft rubber to cut down on noise.


LG1r and TRSr Cranks

E*thirteen have two new lightweight carbon cranksets, the downhill LG1r Carbon, and the Enduro TRSr Carbon. Both use the same hollow carbon fiber crankarms, their 1 Degree EXA+ Alloy 30mm spindle and Adaptive Preload Adjuster (APS). The only difference between the two models is the LG1r gets a longer 83mm spindle length. The downhill oriented LG1r will come in 165mm arm lengths while the trail TRSr will have 170mm and 175mm options and weighs 459 grams.


They’ll use their quick connect direct-mount system for the new chainrings, and the lock ring uses the same tool as their bottom brackets.


The 30mm spindles provide a stiff and strong platform base for the cranks. The new 1 degree P3 Connect Polygon interface creates a tough and reliable impact-resistant spindle and crank arm junction, with a supposed 18% strength increase.
