How do you like your Manitou fork? Is it the tower pro?
Yup that looks to be a 2011/12 Tower Pro by the decals. In mid-12 they changed it slightly and upgraded the internal spring from the Medium to FIRM as most of their riders were finding the spring rate too soft.
I have one on my On-One Inbred 29er and love it. Feels like butter all the time, great small bump compliance, no brake dive and a simple "set-n-forget" style fork that just works.
