I think that chamois preference is just as relative as saddle preference. It depends on how we are made, our riding position and length of rides... It is good that we have a choice

Thankfully I have finally found a chamois other than PI 3-D chamois that also works for me - and that is Terry (Liberty shorts). The PI elite chamois certainly isn't very comfortable off the bike, but it works well for my on the bike - and it feels better on rides >4 hours than on small hour long rides. I have tried a couple of other brands but they just don't work for me - either they chafe or they don't seem to provide what I need in the right location.

I suspect that my PI Elite bibs will always be my short/chamois of preference for long rides - as much as I like the Terry Liberty shorts - I don't think they would work for my longer rides.
