Products like E*thirteen components' TRS+ Double Crankset fulfills the needs of modern trail bikes by eliminating the redundant third ring and focusing on strength. The latter comes in the form of a 30mm spindle with a proprietary polygon interface and forged Exalite+ arms.

This addresses one of the weakest links in crank design -- the spindle to arm interface. Spline degradation and uneven surface contact from pinch bolts leads to creaking and loosening, but the three-lobe polygon design (P3 Connect) results in 100% spindle to arm contact. It's a stiffer interface optimized for high torque applications and, with the Adaptive Preload System (APS), bearings receive the perfect amount of preload.

Which brings us to an important point, E*thirteen does not include a bottom bracket with the TRS+ Crankset, and it's not compatible with aftermarket bottom brackets. This is due in part to APS, but mostly because of the 30mm spindle. While other manufacturers settled on a 24mm spindle, the weight and stiffness advantages were too much for E*thirteen to pass up.

To ensure quality and compatibility in this department, E*thirteen covers standard external, BB92, Pressfit 30, and BB30 industry standards. While all E*thirteen bottom brackets come with alloy cups housing angular contact bearings and custom low-friction seals, they also give you the option to upgrade to titanium nitride races for added durability and smoothness.

That said, once you match a bottom bracket to your frame, and torque the arm to proper specifications, E*thriteen's tool-free Adaptive Preload System (APS) simply hand tightens against the bearings. Now you can enjoy tight-tolerances without over-preloading. Moving on to shift rings, two ratios are available, either 38/24T or 36/22T depending on your goals.

The TRS+ Double uses E*thirteen's shift rings that are 8, 9, and 10spd compatible. They are machined with ramps and pins that optimize gear changes for fast and crisp up and down shifts. The E*thirteen components TRS+ Double Crankset has a 104 bolt circle diameter and comes in two lengths; 170mm or 175mm.
