John S.wrote a review of Niner Carbon Seatpost on August 3, 2017
Familiarity: I've used it several times
This was my first go around with a carbon seatpost and likely my last. About 10 rides in on flowy mountain bike trails the seat post snapped in half midride. Not a fun hike back. Will be sticking with aluminum going forward. Certainly not had that happen with any of those. Frustrating for the premium price paid for this.
