The e*thirteen TRS is all about functionality, simplicity and reliability

Review: e*thirteen TRS+ 150 mm dropper post

Benny 02. April 2017

Benny got his hands on the new TRS+ seatpost. Its fully mechanical design - cable actuated + coil sprung - makes it an efficient, reliable, and highly functional alternative.

Many manufacturers have now added dropper posts to their portfolio. No wonder, few other products have changed mountain biking like the telescopic seatpost, providing more safety and versatility. e*thirteen is the latest to join the club. Its TRS+ features a simple, full mechanical design with 4 lock positions. Benny has tested the 150 mm version.

Simple Installation

The installation of the TRS+ is simple and straightforward. First I taped the cable housing to the end of the hose of my current post to pull it through the frame. Then I installed the remote lever on the handlebar, before cutting housing and cable at the correct length. The cable head is hooked into the bottom of the post instead of the lever, making post removal and cable tension adjustment at the lever very easy.

The seatpost head has two bolts that fit into the slotted top plate of the clamp. This is great, as the bolts don’t have to be removed completely for saddle installation or removal.

Serviceability

e*thirteen also underlines the post’s serviceability. I did not take it apart, but the coil sprung post in combination with the cable actuation speaks for itself. This dropper post promises to be durable, reliable and to withstand a lot of abuse.

Smooth and exact handling on the trail

The shifter style lever actuates the post very effectively, requiring little force and comparably less than a Rock Shox Reverb remote lever. Although the lever is compatible with a matchmaker adapter for SRAM. I went without one as it fit more ergonomically into my cockpit set-up. Shimano I-Spec adapters are unfortunately not yet available.The cable is clamped at the lever which makes for easy adjustment.

The lever is fitted with grip tape. Nice to have, but not really necessary in my eyes. Maybe I will learn to appreciate the benefits on a really rainy day.

The coil sprung post reacts pretty aggressively to the lever commands. E*thirteen claims consistent speeds at all temperatures. I can see this advantage to air sprung systems that are hydraulically actuated, but did not have the chance to test this. The post locks into the four set positions, making noticeable sounds.

Since it’s a mechanical lock, lifting the bike by the saddle will do it no harm unlike an air sprung system.

Smooth operator: The TRS+ can be pushed in with one finger.

Dropping the post is child’s play. The coil gives little initial resistance and pushes in easily, allowing me to focus on the upcoming descents.

Benny's verdict

The e*thirteen TRS+ 150 mm dropper post performs great. Its smooth handling, simple design and shifter style lever make it a true alternative to its hydraulic competitors. The simple and easy installation are another great advantage.
