OPEN UPPER 2.0: An RTP Red XPLR Build

OPEN's fastest gravel frame in bare RTP carbon, built 1x with SRAM Red AXS XPLR and ENVE G Series.

This OPEN UPPER 2.0 is the latest and greatest in fast gravel. It's everything that was loved about the original OPEN UPPER with a decade of refinement. The frame is more aero, more adjustable, and easier to maintain with a threaded bottom bracket and UDH.

This UPPER 2.0 is in OPEN's "RTP" or ready-to-paint option. That means it's as light as it gets, with no excess finishing or paint to weigh things down.

Our client selected Enve's G SES 4.5 Pro wheels for a wide internal rim width that pairs perfectly with the 45mm Schwalbe G-One RS Pro tires. That means a wider contact patch, and more confidence in the loose dirt and dust on our local trails.

SRAM's XPLR groupset needs no introduction. It's quickly become a favorite for builds spanning a variety of use cases here, as the simplicity, shift speed, and reliability are unmatched.

The OPEN UP and UPPER 2.0 have been pretty widely asked about, and after doing our first build on the new models we're excited to be able to offer them. The original UP and UPPER were top picks for us when riders were looking for versatility out of their gravel bikes. We can say the refreshed frames are even better in that regard: they're still super light and responsive, but they now offer upgraded modern standards and an aero benefit.

OPEN's new BAR System allows for fine tuning of the stem length in a way no other bike can. That lets us dial in your fit perfectly, with no worries about getting used to longer reach hoods or a new frame that's a few mm different, as we can adjust the stem in small steps as part of the bike fit and build process.
