Why We Like The MCR RDO 4-Star GRX 1x Gravel Bike

We've always wanted to go on a magic carpet ride, and that's why we're riding the MCR RDO 4-Star GRX 1x Gravel Bike. It's a bike for adventure and for pushing ourselves further, mile after mile. The MCR maximizes rider comfort and pedaling efficiency by offering the smoothest possible ride on a drop-bar bike, making the navigation of rough gravel roads over countless miles a much more pleasant experience. With 40mm of rear travel an1d a 40mm Fox StepCast fork, we'll be flying over the bumps and washboards that would usually have us rattled. While we're riding, we can count on reliable and decisive shifting from Shimano's GRX 1x groupset. The rear derailleur's clutch mechanism reduces dropped chains and chain slap so we can pedal on with a quieter ride. Whether we're riding gravel flats or two-track shortcuts, the MCR is the bike to get us inspired and moving.
