Sparks is getting ready to head off on a Snafu trip on the west coast in the next few days so he came by the shop to spruce up his bike. After a few mins of talking about how some people were SOOO upset about his seat tubeless bike we figured out a way to fix the problem. All it took was a full size aluminum post and a seat clamp. Now his chromoly frame has an aluminum seat tube. Stronger than seattubless yet lighter than chromoly?? New trend??? hahah! Who knows!
