I am newish to cycling. I got a 2012 Trek Madone 4.5 WSD this summer and loved it. Rode as often as I could prob. 2x a week. Falling off towards the early fall. Now that it is winter here in the NE. I got myself a trainer and have been riding for the past week again and i am loving it. I am just having one issue my tailbone hurts. I can live with my seat bones being sore I completely understand that they need to get stronger and used to the saddle, but i am not understanding why my tailbone is feeling bruised. The saddle on the bike is Bontrager Affinity 1 WSD, steel rails, I don't know if this could be the issue or not. I am a Athena about 254 at 5'4''. so that might have something to do with it also. I was wondering if any might have a suggestion on what might be the issue. I rode 49miles this week on my trainer and i love it beside the butt pain.
