E-Thirteen to ship its dropper post this month

Published March 3, 2017

PETALUMA, Calif. (BRAIN) — E-Thirteen will begin shipping its first dropper post, the TRS+, on March 15. The company first showed the TRS+ at Eurobike last year. 

The company said it designed the post to be fully mechanical, home servicable and easy to install. It uses a cable-activated remote and coil spring instead of an air spring for reduced maintenance. A heat-treated, cable-actuated cam locks the post into one of four height positions.

A shifter-style paddle remote pivots on sealed ball bearings. The cable clamp puts the cable lug at the seatpost so disconnecting the cable is easy.

Since showing the prototype at Eurobike, the company has made a few changes, including:

  • The main spring was split in two and a spacer was added between the two springs to prevent noise and wear.  
  • Threads were added to the cable anchor knob for easier seatpost removal while traveling or servicing
  • The cable anchor knob now has a rubber insert that makes service and set up easier by preventing the knob from sliding down the housing
  • The bottom cap interface is now compatible with a common Shimano freewheel tool
  • The main seal has been updated to a SKF low-friction, dual-lip seal
  • The head and saddle clamp were refined to drop weight and improve aesthetics
  • After testing, athlete-preferred height stops were changed to 150-125-75-0 and 125-95-65-0
  • Lever design is lighter, lower profile, and now has a forged body and composite barrel adjuster
  • The machined logo on the lever's thumb paddle has been replaced with factory installed grip tape

The post has an MSRP of $279 and will be available in four versions: 30.9 diameter in 125mm or 150mm travel, or 31.6mm diameter in 125mm or 150mm travel.
