recently bought a Prologue to fit on my TT Bike. A friend recommended it following my last Ironman. Fitted it to my road bike just to test and was amazed by the level of comfort after a couple of tweaks. Subsequently ordered another one as I am not taking it off my road bike. I live in Berlin, Germany and went for a ride on a very cold Sunday morning. With my previous saddle my nether regions would be very cold and I would not feel comfortable in my tights. However, due to the improved blood flow my midriff felt warmer and I felt much more comfortable in my tights as I did not have that numb feeling down there. Thought you might find the feedback interesting as another USP. Now I am waiting for the Attack as this will go well on the TT bike.
