NCX Seatpost

I got the 30.9 NCX seat post for my Aventon Aventure. I couldn't be happier. The seat post takes the jarring vibrations out of the ride. It has improved the overall comfort of riding.

Fantastic addition to my Aventon bike.

I purchased an Aventon Aventure.2 from Erik’s this season. It’s a great bike by nearly all accounts but the ‘hard tail’ (ie no rear suspension) was surprisingly hard on my tail section. I could feel every sidewalk imperfection, in spite of the fat tires. Ugh. Enter the Suntour NCX (model SP25) suspension seat post. In a word: game-changer. Significantly smoothed out the smaller bumps and expansion joints that were really bumming me out. I should have bought this seat post on day 1… Aventon should offer the SP25 model (30.9mm not available on their site’s drop down menu as an option). Ok, I avoided the counterfeit worry and bought directly from Suntour with a discount. Worth every penny. Thanks!
