It rode like a wet noodle up hills, at least for me. It got sold to a lightweight sit and spin type dude, who loved it.

I usually weigh stuff and then forget. My 78 Masi with 36h race wheels was just about 20# even built up (with pedals). 2016 Mercian KOM touring frame is 4.9 lb. I forget what the fork was. Material is 725OS in whatever gauge they felt was appropriate for a 64cm loaded touring bike. Feels lighter than the Masi going up hills, which is a very very good bike (obviously).
