Hi Zteve,
Interested. I have a 2010 C14 ABS. Can you hold them for a bit today? Have you also used risers? I have used 1 5/8" (which are for sale on here now) and I am currently using 2" risers with Phil's wedges. Still not quite there for longer rides. Also have a Corbin seat which helped the wife more than me. I'm 5' 10 with a 32" inseam. If you have used risers how would you compare them to the extenders? What is your reason for selling them? At least at your price I wouldn't take as much of a hit if I didn't like them and had to resell. I'll be around the computer for a while if you can get back to me. Thanks. email concours14@frontier.com if you prefer.
Jack
