Why this bike stands out
A race-focused carbon gravel platform with Shimano electronic shifting, wide-range gearing and carbon wheels already included.
Carbon wheel speed
Miche Sterrato 45 Carbon wheels make this build feel quicker, more responsive and more complete than the alloy wheel entry options.
Real gravel range
The 40T chainring and 10-51T cassette give the bike enough climbing range for steep gravel while keeping the drivetrain simple and race-ready.
Value argument
Why this build is good value
The E628G4ST build is a strong value point in the Rave SLR ID2 lineup because it combines three upgrades that matter most: the HUS MOD + Liquid Crystal Polymer carbon frame, Shimano GRX Di2 electronic shifting and Miche Sterrato 45 Carbon wheels.
Compared with the lower-priced GRX Di2 / Miche Graff build, this version adds the faster carbon wheel package while keeping the more accessible alloy Barra S2 handlebar and Stemma S2 alloy stem. That makes it a smart choice for riders who want performance where they will feel it most on the road and gravel.
