Gravel // Red Rock
The Indigo Red Rock serves as our premier gravel bike, designed to be your everyday companion on gravel roads. With a strong focus on durability and comfort, it’s the ideal choice for extended off-road adventures. Engineered around a 1x drivetrain and wide-ranging gearing, the Indigo Red Rock is well-equipped for any off-road pursuit. Featuring generous clearance for up to 700 x 47mm tires (or 50mm on 650B wheels), along with disc brakes utilizing standard thru-axles and an any-road capable geometry, the Indigo Red Rock stands out as the most versatile bike in our lineup.
Features:
Tire Sizes
The frame offers versatility, allowing you to ride it like a road bike with 700c wheels and narrower 28-32mm tires, or configure it as a gravel bike with up to 47mm tires. If you venture onto looser or rougher roads, you can switch to 650b wheels and run up to 50mm tires. All our wheel set ups come tubeless and preinstalled with Stan’s No Tubes sealant.
Straight 44mm Head Tube
Our use of a straight 44mm head tube enhances stiffness and durability at the front end. Paired with our carbon fork featuring a 1.5-inch tapered steerer, it delivers the stiffness needed for precise steering response and agile handling.
142×12 Rear Spacing and Thru Axles
Adhering to the current standard for gravel bikes, the Indigo Red Rock incorporates 142mm rear end spacing and 12mm thru axles to bolster frame stiffness and keep you grounded. The flat mount disc brakes not only provide a sleek appearance but also deliver reliable braking power.
BSA Bottom Bracket
The 73mm BSA threaded bottom bracket, a long-standing standard in the bicycle industry, offers years of serviceability and compatibility.
