The Aspero GRX RX827 Di2 1x Gravel Bike gained real tire and mud clearance over the previous Aspero, room born out of watching bikes clog up during muddy gravel races. Seat stays sit lower and the front end backs off some stiffness, together taking the edge off a long, rough day in the saddle. The frame also spends less rider energy fighting a headwind than the outgoing Aspero, a gain that adds up over hours on exposed gravel. What Our Gearhead(R) Experts Are Saying:"I've run GRX Di2 through washboard descents and mud-caked climbs without a missed shift. The electronic actuation doesn't care if my derailleur is caked in grit, it just clicks into gear."Heads up! We do our best to keep bike specs and images current, but occasional component changes can happen without warning, and sometimes the photos might not show the exact build you'll receive.
