Been using a 49cm masi giramondo. I took it on a 600km tour last year and was having some saddle sores. I think it may of been a problem with the saddle and not with the frame size. Ive swapped it with a Brooks so I think ill be okay. My question is there any hindrances to using a frame thats a couple cm small for me. Im 6ft and think im better fit for 53 or 55. But for touring where speed doesnt matter and only comfort should this be an issue? Also what are our opinions on riser stems for comfort. I heard there are more cons than pros that come with it.
