So the little velcro straps on my Fly 6[v] don't last for ever, but to replace them I have to buy a pack including an aero seat post adaptor and a a short and a long velcro strap. Don't need the long strap and I have two aero seat post adaptors, anyone want 'em? (postage only), also have a couple of those wedge things that you can use to adjust the angle of the light.
