Just thought Id share with you guys: I was just visiting Aspen co a couple weeks ago. I rode up the Shadow mountain (lift 1a) SLI lift. I was intrigued by the new sheave frames that have been added to the lift since I last visited. The depress towers use a standard TSI sheave frame, but the ones on the support towers appear to be custom made for this lift. They are similar to the TSI frames but have anti derailment guards that are alike the ones found on SLI frames.

A picture of the old upside down Riblet sheave frames the lift used prior to these new ones. For whatever reason, this tower (not sure of the number) still uses the old Riblet frames.
