Synced up with the debut of a new GRX Di2 gravel group over the weekend, PRO has a new Discover Aero Carbon bar and boxy 10 stem to dial in a fast gravel race bike cockpit. Set to roll onto the race circuits at Unbound this coming weekend, the new Pro Discover offering promises aero gains, full cockpit adjustability, and internal cable routing flexibility to work with almost any gravel bike setup.PRO Discover Aero Carbon gravel bar & 10 stem(Photos/PRO)Aero is everything, even in gravel, so Pro is getting in on the aerodynamics game with a new carbon bar and steeper stem to get your cockpit down (or alternatively up too). But while most companies are going fully integrated to go aero, Pro sticks with a separate bar & stem concept for full fit flexibility. Plus, they do internal routing in a simple way thats clean if you want it, but hassle-free if you prefer a more traditional setup.So, whats new?All-new Pro Discover Aero Carbon bar ergonomicsThe Discover Aero Carbon bar is only Pros second carbon handlebar in the lineup. It tones things down a bit from the adventure-riding direction with regards to shaping, settling for a reasonable 12 flare to the drops. But then Pro adds a gentle 4 forward sweep, and 4 downward slope to the tops which they say will help riders comfortably maintain an aero position while riding fast on the flattened tops.Those flat tops curve around the first bend and then rise back up towards the round section where you mount the hoods staying wide and flat. That should make for a super smooth comfortable transition onto the hoods assuming you wrap your bar tape well. The aero top is just about 40mm deep across the flat, and just 17mm thick, meant to be fully wrapped with bar tape for off-road comfort.The compact bend bar comes in three widths 40, 42 & 44cm wide, measured center-center at the hoods. And with the flare, it measures about 4cm wider outside at the end of the drops.Pro combines the bars T700 unidirectional carbon with their signature Dyneema fibers to increase compliance both filtering out some gravel road buzz and improving durability.A separate new stem to matchIntegrated cockpits might be all the rage right now, but for the vast majority of riders the combination of a handlebar and stem simply allows for a better bike fit Mark Kikkert, PRO Product Development Team ManagerCan I just thank Mark for that statement, real quick?Pro already had a relatively conventional rounded box section +/-6 alloy stem. But now it adds an even more boxy angular +/-10 stem to offer a bit lower position on the bike. The new stem has a more aggressive machined aesthetic, and what looks like slightly lower stack. But the real update is about getting a lower position on the bike for the #slamthatstem crowd.Again, Pro 3D-forges then machines the 7075-alloy to maximize stiffness at a low weight. Officially, weight claims are essentially the same for the old & new stems, although the Discover Stem 10 comes in one shorter size than the 6, so I expect this one could weigh ~5 or 6g more.

Much like we just saw with Ritchey, Pro have recognized the increased stresses riders are subjecting gravel bikes to, so theyve upped their test standards to match, delivering improved rider safety.PRO Discover Aero Carbon handlebar & Stem 10 Pricing & availabilityThe all-new PRO Discover Aero Carbon gravel race bike handlebar sells for 350 in three widths 40, 42 & 44cm. And the new alloy Discover Stem 10 sells for 100 in 7 sizes 60-120mm. Pro ambassador and elite gravel racer Laurens ten Dam is set to race the new cockpit this coming weekend at Unbound. But for the rest of us, the new carbon bars are slated to be available in your local bike shop and through regular Pro/Shimano distribution channels by late June or early July. Were waiting to hear back about the new stem availability.PRO-bikegear.comThe post PRO Discover Cockpits Go Aero with Aero Carbon Handlebar & Slam That Stem 10 appeared first on Bikerumor.
