For the taller riders, this is a must, as many seatposts that come with bikes are too short.

Very good, long and strong seat post.The post that came with my bicycle was too short, making riding difficult. This post fit the bill and wallet to fix the issue. It fit snuggly into the shaft of the bike frame and only required a few taps from a mallet to pop it into place. Once I put on the new seat zand tighten everything, it was good to go. The length guide on the side it nice to adjust the height of the seat to a comfortable length for your height preference.

I wish the bike seat post was labeled not only in metric but in SAE Sizing. The post was very long but so were all the other ones I looked at. I had to resize the post to fit my and it worked out great. Nice product, just check the length to make sure it fits your bike.

Love this seat post. I can adjust it easy because the markings on the post allow you to dial in the right height. Made well should last a long time.

Worked on my sons 20 bike. Had to cut post down some as it put seat height to high. Seems like good quality for the money.

Vraiment beau matériel mais je me suis trompé de taille, alors mesurez bien l’intérieur du tube du cadre du vélo avant de commander, ne faites pas comme moi 😊😊😊…

I can’t get the correct size for my bike, 25.4mm is too small and 27.2 is too big!

Fits very VERY snug after securement, good finish on post metal and no extra parts to break under my extra weight like on all the local bike shop "hex bolt" seat posts. I'm about 250lbs 6 foot 2 inches currently (for reference). And for like 8 dollars what more could you ask for? Also, the default "bolt & nut clamp" attachments fit just right on the top (see pics). Very VERY glad I ordered. I got the 30.4mm one by the way. THANK YOU. Got here today (a day after ordering). 👋👋
