I know this is a question which is asked over and over again, and there are posts all over the www re this. But this is MY question, relating to ME - so please bare with me. I am currently a healthy 105kg squashed into 1.87m, but aiming to bring the weight down to <95kg in due time. I ride a 29" hard tail mtb at the moment, and I enjoy it and I like my bike. But... I had a small operation to my bum area a few years ago, and when I am out on long rides, my bum gets sore and swollen. Will a 29" dual suspension suit my bum better?
