Every detail dialed, the PRO Missile EVO Carbon Stem is the finishing piece
What Our Gearhead® Experts Are Saying:
"When I am speccing a full TT build around the Missile EVO system, this stem is the piece that makes it feel intentional rather than assembled. The integrated routing, Di2 compatibility, and UCI legality check every box, and the UD carbon keeps the front end weight where it needs to be for a performance setup."
A purpose-built time trial cockpit demands that every component work as part of a unified system rather than a collection of compatible parts. The PRO Missile EVO Carbon Stem is engineered specifically to fulfill that role within the Missile EVO ecosystem, serving as the structural and aesthetic backbone that ties the aerobar, extensions, and front end geometry into a single coherent unit. For athletes and fitters building a serious TT or triathlon setup, it is the piece that makes everything else make sense.
UD carbon construction delivers the torsional stiffness required to translate a rider's power and steering input without any flex in the front end, while keeping overall weight competitive with the demands of a performance build. The -1 degree angle and 85mm length are optimized for the forward, flat body position that time trial and triathlon racing demands. At 31.8mm clamp diameter, it pairs directly with the Missile EVO Aerobar and is dimensionally consistent with the broader Missile extension and armrest hardware.
Integrated cable routing is not a cosmetic feature here. In a TT setup where aerodynamics compound over the duration of an effort, a clean front end free of exposed cable loops and housing bends contributes real, measurable benefit. Shimano Di2 compatibility ensures the stem accommodates electronic shifting without routing compromises, keeping the cockpit tidy in both mechanical and electronic builds. UCI legal certification means this stem is cleared for sanctioned competition at all levels, from local time trials to elite triathlon. For anyone assembling a Missile EVO cockpit with race-day intent, this stem is the correct foundation.
