SERAPH GR257 GRX

SERAPH GR257 – Gravel Without Limits

Ride what others walk.

The SERAPH GR257 is a full-carbon gravel machine built for riders who see rough terrain as an invitation, not a warning. From the integrated HB047 carbon cockpit to the GR257 carbon frame, fork, and seatpost, every gram of unnecessary weight—and vibration—has been stripped away.

Shimano GRX 820 – Gravel's Benchmark

The complete GRX 820 mechanical groupset delivers rifle-bolt shifting through the GRX 822 rear derailleur and FC-RX820 42T crankset. Paired with a wide-range Shimano cassette and CN-M8100 chain, it gives you the torque to climb loose grades and the speed to hammer the asphalt home.

Big Rubber, Race Wheels

LC50C38 T800 carbon rims laced to DT370 Micro Spline hubs with Pillar aero spokes create a wheelset that tracks like it's on rails. Wrapped in MAXXIS 29×2.25 tires, the GR257 clears terrain that sends ordinary gravel bikes packing. Shimano hydraulic disc brakes keep it all under control when the descent gets rowdy.

Built to Roam

The SERAPH GR257 proves you don't need a boutique price tag to own a big-tire, fully integrated carbon gravel bike with Shimano GRX. Tougher routes are calling. Go answer them.
