I will readily admit as far as creaks and rattles etc I can become obsessive. I have had my Domane 2021 HP for a few weeks now and have put about 90 miles on it. The last two rides my Iso Speed I believe is making a creaking noise when I pedal. I came home yesterday and adjusted it to the softest setting and sprayed some lubricant on the seat post in case that was the cause. I can actually duplicate it by putting pressure on my seat and seat post and I can hear the noise on the bottom part of the Iso Speed that is on the bottom part of the top tube. It is kinda driving me nuts. I thought I would reach out to all of you before running it back over to my LBS. Btw it didn't do it when I first rode it. Thanks everyone
