I've been using Bontrager since then, and no problems so far.
YES! that is EXACTLY what I experience! Supposedly Specialized has "just fixed" this problem with their new tubes -- makes you wonder if that is true! I just hate to spend extra money on a "better product" only to have the same problem surface. Good to know about Bontrager.
