With all-mountain riding and enduro racing continuing to increase in popularity, e*thirteen chose to create a line of components designed specifically for this usage. The TRSr series (TRS stands for Trail Security, the ‘r’ is for Race) includes cranks, pedals, wheels, and chainguides intended to be enduro race worthy. The TRSr crankset is constructed from forged and machined aluminum, and utilizes a spiderless chain ring design, with double and single configurations available.
Pinkbike’s Take:
Previous versions of e*thirteen’s cranksets had a reputation for being finicky to set up, but this has been addressed, and installation of the TRSr is now as simple as pushing the drive side crankarm spindle through the bottom bracket, tightening the non-drive side arm until it bottoms out, and then adjusting the preload ring by hand to remove any remaining play. The PF30 bottom bracket is unique in that it has an aluminum threaded sleeve that joins the assembly together, rather than the more common plastic tube that sits between the bearings and around the spindle. Proprietary tools are required to install the bottom bracket and chainrings, but these are included with the crankset.
