SzepterCore 4 SRAM Force XPLR eTap AXS

The range breaks into three Core builds that share the same underlying carbon frame concept, with the biggest ride-defining differences coming from fork, shifting ecosystem, and whether you get a dropper. Core 4 is the full statement build with RockShox Rudy Ultimate XPLR and SRAM Force XPLR eTap AXS, plus a Reverb AXS XPLR dropper. Core 3 keeps the Rudy fork but steps down to SRAM Rival XPLR eTap AXS and deletes the dropper, which will appeal to riders who want the fork’s comfort and control without adding another service item. Core 2 shifts the value focus further, using a SR Suntour GVX 32 fork and a Shimano 1x12 drivetrain with a wider-range 10-51 cassette, again without a dropper.

Across the SRAM builds, gearing is XPLR 10-44 with a 38T ring, which some riders find adequate for mixed terrain but may feel tall if your rides skew toward sustained steep trail climbs. Braking on the SRAM builds uses a larger front rotor than many gravel bikes, matching the bike’s rough-terrain intent. Stock wheels are alloy across the line; several reviewers point out that wheel weight is a noticeable limiter relative to how capable the frame and fork feel, making wheels a logical performance upgrade if you’re trying to sharpen acceleration without changing the bike’s core character.
