E Thirteen Vario Dropper SeatpostThis mountain bike (MTB) dropper seatpost features a 3D forged stanchion with integrated head, which offers increased stiffness as well as enhanced durability upon any unexpected hits to the saddle. As bikes become more aggressive, saddle and dropper post hardware must also accommodate slacker seat angles, so e.thirteen designed this model with an extra 12mm of fore/aft saddle adjustment and 28 degrees of total seat angle adjustment.Gas-Charged Spring with Infinitely Adjustable TravelThe Vario Dropper Post uses a proven, gas-charged spring allowing infinitely adjustable travel, and requires 20% less compression force than the competition. e.thirteen’s unique upper bushing allows travel adjustments in 5mm increments to a 30mm maximum. Travel adjust is tool-free, no need to even remove the post from your bike.e.thirteen recommends pairing this model with the cable-actuated Vario 1x Dropper Lever (available separately). The fully serviceable lever is shielded by a durable aluminium body, which offers three mounting positions and has a high grip paddle pivoting smoothly on two sealed bearings.Features: Material: 3D forged stanchion with integrated head Use: MTB Compatibility: All frames with internal cable routing for dropper seatposts Infinite travel gas spring Extra 12mm of fore/aft saddle adjustment 28 degrees seat angle adjustment Tool free travel adjustments in 5mm +/- Cable actuated Included: Vario dropper seatpost and owners manual Lever Included: No, available separately Weight: 30.9 120-150mm Option: 550g; 30.9 150-180mm Option: 597g; 31.6 120-150mm Option: 571g; 31.6 150-180mm Option: 618gTechnologies: Travel Adjustment: Total overall adjustments can be made in +/- 5mm increments with a max total of 30mm.
