This road frame has a lot of features-S&S couplers head tube pump peg, chain hanger , Enve carbon fork painted to match. It's a nice package altogether. The stem is not the one that will be on the finished bike it is just there for this photo. This ike might do some racing miles but it will definitely be doing some air miles.
The tubing is a mix of True Temper OX and Columbus Life-pretty much my choice for a stout frame that won't be too heavy. The couplers do add weight but the benefit in flight cost savings is well worth the few oz.
