Good day fellow Hubbers, this is my very first post and hope someone will be able to assist. I have been cycling for the last 4 months and I have bought myself a new MTB (Merida Big Ninety Nine XT-M). Over the weekend I took my new MTB for its first ride about 27km. To make a long story short the bike was set up by a reputable Cycling shop in Balito and my buttocks hurts (exactly on the 2 bones in my buttocks Marked in Pink in the attached image) , but not on the usual spot, is it the wrong saddle for me or must I move the saddle a bit more back or just get use to the new saddle? And if it’s the wrong saddle how do I know what is the saddle for me? The saddle I have on my MTB is an Selle Italia X1.
