I have been considering Retul and whatever Trek's new computer fit system is (or at least, the one used by my LBS who is the big Trek dealer in town), simply because I've had some nagging issues that I haven't been able to get rid of in recent years. Not really any pain, but things like my pelvis rotated at an angle on the saddle, sit bones not centered on the saddle which has caused some bad chafing issues, etc. I just need to come up with the money to get it done.
