The HC170 is a saddle for Road Racers. HC [Hard Core] 170g [weight ] is a minimally padded seat with a newly developed [by me] Polymer shell that flexes and molds to the riders butt. It also incorporates our "thigh guides" so the rider doesn't get chafing from the seat edges. It comes in both Black and White finish using a new Microfiber material with a true leather feel. This is not designed for touring, it is a Race saddle and it has very minimal padding in the nose. Our test riders, which were all experienced Cat 1,2,3 cyclist, found it to be very comfortable even on 85 mile training rides.
