This top of the range stem uses the same reverse bolt design but with Ti bolts and a very similar carbon coated body to the Ritchey.
Our sample also came with the optional carbon front cap upgrade to drop it right in among the lighter stems.
As you'd hope for the huge cost it does deliver in terms of increased stiffness too. Both the carbon wrapped body and reverse clamp front plate work to keep the bar noticeably more anchored than on other similar weight stems.
This makes it the obvious choice for more aggressive racers, but you're still paying a lot for the privilege.
