Having been very happy with my old pair of cycling undershorts/nics. I was surprised to see the changes to the chamois and the leg grippers. The legs appear to also shorter than my old ones but hard to tell. The chamois appears to be an upgrade with more layering and shaped more like a traditional road chamois. Likewise the leg grippers are a wider band of dimpled gripper fabric rather than the previous concentric rings of gripper material. First ride is on the weekend and will know more then.
I recently purchased the Epic Bike Short Liner and have ridden in them only once, so these are just my initial thoughts. I know that Mons Royale did some adjusting of their sizing and that worked great for me. Previous Mons Royale shorts I own I had to get in a XL, but my new Epics are a size L and fit great. Fabric is super comfortable and noticeably less stinky after a long ride than synthetic shorts. Looking forward to many more rides in them.
