The new handlebar also has a 20-degree flare for additional stability off road.

The Stealth Off-Road helps mountain bikers maximize power in aggressive riding positions while remaining comfortable and durable. The Stealth Off-Road saddle’s wide nose area and dual-density superlight EVA padding provides support where mountain bikers need it along with a wide, anatomically-perfected sitting area (142mm or 152mm options) for pressure relief on the sit bones.

    Have they mentioned any ETA to market for that Discover DSP Drop Bar Lever? Desperately want one!!!

    • JOM JOM

      I would expect October / November. I have the less flared version on the Pivot Vault I showed in the GRX video… I’m not a huge fan of flared bars, but this one suited me quite nicely. I think you will be quite happy.

        Thanks, Jom! It’s actually just the dropper post lever I’m interested in. I am running Salsa’s Cowchipper bars on my bike and love them; I need the shortest reach possibly to the drops, and these new bars from Pro have a longer reach than the Salsas.

    Do you know if the Discover Carbon Gravel handlebar is compatible with clip-on aerobars?

    • JOM JOM

      Steve, that’s a question for Shimano / PRO, etc. Sorry.

    I called and they are compatible with Clip On aero bars. Are the tops of these bars flattened like the Enve gravel bars?
