Synced up with the debut of a brand new GRX Di2 gravel group over the weekend, PRO has a brand new Uncover Aero Carbon bar and boxy 10° stem to dial in a quick gravel race bike cockpit. Set to roll onto the race circuits at Unbound this coming weekend, the brand new Professional Uncover providing guarantees aero features, full cockpit adjustability, and inner cable routing flexibility to work with virtually any gravel bike setup.
PRO Uncover Aero Carbon gravel bar & 10° stem
Aero is every part, even in gravel, so Professional is getting in on the aerodynamics sport with a brand new carbon bar and steeper stem to get your cockpit down (or alternatively up too). However whereas most firms are going absolutely built-in to go aero, Professional sticks with a separate bar & stem idea for full match flexibility.
Plus, they do inner routing in a easy manner that’s clear in order for you it, however hassle-free in the event you choose a extra conventional setup.
So, what’s new?
All-new Professional Uncover Aero Carbon bar ergonomics
The Uncover Aero Carbon bar is barely Professional’s second carbon handlebar within the lineup. It tones issues down a bit from the adventure-riding path as regards to shaping, settling for an affordable 12° flare to the drops.
However then Professional provides a delicate 4° ahead sweep, and 4° downward slope to the tops which they are saying will assist riders comfortably preserve an aero place whereas using quick on the flattened tops.
These flat tops curve across the first bend after which rise again up in the direction of the spherical part the place you mount the hoods – staying broad and flat. That ought to make for a brilliant easy snug transition onto the hoods – assuming you wrap your bar tape nicely. The aero prime is nearly 40mm deep throughout the flat, and simply 17mm thick, meant to be absolutely wrapped with bar tape for off-road consolation.
The compact bend bar is available in three widths 40, 42 & 44cm broad, measured center-center on the hoods. And with the flare, it measures about 4cm wider exterior on the finish of the drops.
Professional combines the bar’s T700 unidirectional carbon with their signature Dyneema fibers to extend compliance – each filtering out some gravel street buzz and enhancing sturdiness.
A separate new stem to match
“Built-in cockpits is likely to be all the craze proper now, however for the overwhelming majority of riders the mixture of a handlebar and stem merely permits for a greater bike match”
– Mark Kikkert, PRO Product Growth Crew Supervisor
Can I simply thank Mark for that assertion, actual fast?
Professional already had a comparatively typical rounded field part +/-6° alloy stem. However now it provides an much more boxy angular +/-10° stem to supply a bit decrease place on the bike. The brand new stem has a extra aggressive machined aesthetic, and what appears to be like like barely decrease stack. However the true replace is about getting a decrease place on the bike for the #slamthatstem crowd.
Once more, Professional 3D-forges then machines the 7075-alloy to maximise stiffness at a low weight. Formally, weight claims are basically the identical for the previous & new stems, though the Uncover Stem 10 is available in one shorter measurement than the 6°, so I anticipate this one may weigh ~5 or 6g extra.
