my totally ****ing insane 58cm makino has virtually no overlap. when i switched from medium to large clips, a little was introduced, but i've never noticed it while riding. it's 80 seat, 76 head.
riding that ****er on the street regularly will make you sterile. the prostate massage is pretty orgasm-inducing, but can be too intense. it's super fun to ride in races and other events, but it'd be raw to commute on.
