Hmm...so yesterday I bought the new saddle, installed it and could test it when I had my 2,5 hour training today. It feels the same! It got a bit more padding but that was not the 'sore spot'. It still felt that the weight was more on the front than the back side. For now, I will put my mtb saddle on it tonight and tomorrow I have a 3 hr. training ride. Suggestions what the problem could be?
