FrancoR 0 #1 June 2, 2004 Can anybody explain the advantages of tubes with outer rings like these: http://no-limit-extremsport.de/pages/tube.htm I was at two dropzones this past weekend and both had these tubes. My tube doesn't have this outer ring. All the previous theads i read never mentioned tubes with outer rings. Has anybody ever seen one on the west side of the atlantic? FrancoIf it does not cost anything you are the product. Quote Share this post Link to post Share on other sites

jmfreefly 0 #3 June 3, 2004 Having just finished construction on my newest tube, I would guess that it is actually for ease of construction. My tube has the rim with the tube sewn around it. Unless you have a machine that has a very high foot adjustment, sewing this is a royal pain in the butt. Additionally, getting the tube sewn symmetrically is a challange with this honkin rim in the way. Making several attachment points to the tube seems much easier to do. j Quote Share this post Link to post Share on other sites
