Does anyone have experience with carbon road bars and 2- or 4-bolt stems?
Easton indicates that their EC90 Equipe bars need a 2-bolt stem. However, other stem manufactures specifically state that their 4-bolt stems may be used for carbon or other lightweight bars.
Is this a marketing gimmick, a safety issue, or a combination of the two?
