The e*thirteen TRSr crankset is the brand's new range-topper, and its aimed squarely at those who value their time between the tapes. The small ‘r’ stands for ‘race’, in case you were wondering.
At 674g – weighed with a bottom bracket (BB) and 34T Guidering M direct-mount chainring – it’s seriously light. It’s extremely stiff too, and the CNC machined finish is superb.
The oversize 30mm axle has a polygonal interface that’s claimed to improve the crank/axle connection but can only be used with e*thirteen BBs. Previous incarnations suffered from poor sealing but our latest BB is still smooth after six months. It’s just a pity it has to be bought separately, which pushes the price even higher.
The Guidering M chainring has an integrated spider and mounts directly to the driveside crank arm. Coupled with a clutch mech, the narrow/wide tooth profile keeps the chain securely in place, so a chain guide is optional. It’s available in sizes 28-38T and can be retrofitted to e*thirteen's TRS, TRS+ and LG1 cranks.
The TRSr is a seriously stiff piece of kit and about as minimal and ‘racy’ as enduro-specific cranks get. It’s expensive for an aluminium crankset though – particularly when you consider the added expense of forking out for that BB too.
