Enduro Collar looks like a good thing to toss into the pack for long adventures.
…or just at the top of your post. Are we really THAT weight conscious these days?
I actually ended up putting the collar at a specific place on my Reverb. Turns out I don't like the seat totally down. I'm on a Blacklight now (sold the bike w/ the Reverb), so I'll have to see if I can make something similar work for adjusting the slammed seat height.
