title says it all really....I've been getting achy cheeks in the last few months (not chaffing) after only 40 or 50k. Thought the old bib shorts may need replacing so got a pair of Rapha core bib shorts but the problem still persist. Do saddles start failing after a while? I'm currently using a Fizik Antares that came on the Canyon I have, guess I've done 2k on it? New saddle, new bibs shorts or is it a case of Rule 5?
