>>1217765the most important thing is
a. you get some clipless shoes that fit you really well
b. you get the bike fitted by a pro shop (costly but worth it)
Out of those, i'd get the scott speedster. Personally though, I think you should either spend more, get say pic related for $1000, or with 105 for $1300. Or spend less, like $200 on a 90s bike.
