My Gaffrig speedo is leaking down. The thing was down a hair last year but has dropped even more over the winter. What is it you put in these things and how do you do it?

Glycerin I believe. You can buy that from your local drug store. I sent mine back to Livorsi to have it refilled and resealed with new o-rings.

I usually just send the ones with problems back also they return them pretty quickly

Pull it and send it back to Livorsi. Ed Mannion is who you want to talk to. They will be very happy to fix it for a very nominal charge, and you will have it back in a couple days.

i use vodka pref. grey goose

in case of emergency......."break glass" with a little hammer chained next to speedo ?????????

try putting a GPS one in its place.... youll be a lot happier and youll actually know how fast you are going instead of being plus or minus 20 mph

$80. I just called them and am about to send mine in.
