Ok so i broke my friends seat post and he wants me to buy him a new one so im looking for a Schwinn 250-mm (8.5-inch) Seat Post thats relatively cheep. so if anyone has one or knows of where i can get one at tell me also if you know of a store in Arizona that sells them tell me.
You probably will not find a Schwinn seatpost at your corner bike shop.
Unicycle.com usually keeps replacement Schwinn seatposts. They even have different lengths.
Call them if you want to make sure your getting the right one, and ask for USPS shipping instead of UPS, which I believe should be a lot cheaper.
