This is the shock off my beloved Salsa Big Mama. Medium compression tune, low rebound tune. I took it off to replace the bushings and noticed it leaking oil from the seal at the Pro Pedal lever. It's a perfect candidate for PUSH or Avalanche to work on. I was going to, but I found a used Monarch RT3 instead. Just pay shipping plus $1 for my gas and time and it's yours. I can send USPS, UPS, or FEDEX, you choose.
