Obviously You should order the correct size post or get a seat post shim. At the time I ordered the seat post to fit my Level (27.2), but I wanted to be able to switch my seat post to my Fat Bike which was a larger diameter. You can get a seat post shim on Amazon. Aventon Aventure specs say the seat post is 30.4mm.The 27.2 mm is definitely not the correct size for the Aventure. My measure of the tube shows it to be approximately 31.75 mm. Not sure how exact the new seatpost must be to work.
Obviously? A customer service rep confirmed the 30.4mm diameter, but I have looked through the aventure manual and do not see it. Anyway, ordered the 27.2 suntour post and an appropriate shim. The suntours seem unavailable in the u.s. currently. The shim will likely arrive long before the seat post.Obviously You should order the correct size post or get a seat post shim.

Seat post first. That is where you will realize the greatest comfort gain in my opinion.Just following up looking for more on comfortable seat. Or susp seatpost. I thought my butt would toughen up. I have about 230 miles on the bike in 2 plus months.. My.longest ride is about 13 miles in 45 min. Butt hurting after that. I could probably do 15 miles. My average ride is 8 to 10 miles in 30 to 35 min., try for 4 times a week. I like to ride pas 3 in traffic. Avg. Around 18 mph. On sideroads I'm trying to ride more on lower pas for more exercise. Or noassist at times on flats. I'm still leaning toward a deatpkst first, maybe a C9 seat later? Need to increase my riding time snd distance when I csn..
