Great post Great price

I needed a 27.2 silver seatpost for a retro build. I looked high and low for the perfect post and finally found the State one. It not only looks great with the simple double bolts hidden underneath, but the post is machined well and is quite light. Price was very fair. Can't go wrong with this post.

Does the job well

A nice seat post. Solid and does the job well.

Boycott State Bike Co

I've had my State bike (Vice 2.0) since August of 2014 and I've had loads of issues. I've had my bike in their warehouse shop maybe 3 times for wheel issues (15+ flats in a month) and most recently had the clamp part of the seat post completely snap while biking. Receiving help from and talking to the employees at the shop is like speaking to a wall, no personality and no interest is present in that front office. Save your time and money on these overpriced and underperforming bicycles and take your business elsewhere.


Nice product for the Black Label frameset I'm building. Never any problems with State.
