I beg to differ with how well the Terry Knickers fare on long rides. I have tried them out on one 60 mile ride a while back and had some difficulties with chaffing. They are great for shorter 20-30 mile rides, but I wouldn't trust them for anything much longer. I love my Pearl Izumi's (with the Pressure Relief Chamois-PRT) and my Briko's (found them on sale for about 1/2 off -otherwise they are quite pricey! They are my favorite though!!) Both of those brands have treated me well on many longer rides.

I think this topic is just like much in cycling--it depends on the individual as to tastes and preferences. You find what you like by trial and error (which I know can be expensive, so asking for advice is a good start.)

I have never tried the Chamois But'tr (or whatever it's called ) and am wondering what people have to say about that. From the name, it sounds like it'd be greasy or something. I am doing a 6 day 500 mile ride and think that by the end no matter what shorts I wear I will be hurting a bit. Am wondering if this might be something worth trying to cut down on at least some of the discomfort. Any thoughts?
