Gravel Gearing Explained
A versatile bike setup is an important element to surviving and even thriving with gravel’s unique physiological demands.
Gearing is at the forefront of this versatility with a plethora of options ranging from single to double front chainring setups as well as determining a gear range that allows for a successful and fun gravel riding experience.
In Their Own Words
Stories from the Alliance.
S24O: Sub 24-Hour Overnight
By Phil Thomas
Life, family, and work commitments can often derail big bikepacking adventures into the wilderness. Multi-day events and races are just plain hard to fit into a busy schedule. But the overnighter, the less than a full day S24O (sub-24-hour-overnighter), is a great way to get out and enjoy the bikepacking life without the full commitment.

The Rock Cobbler

A stupidly hard ride, bordering a race. 100+ miles consisting of country asphalt roads, trails, private land, a river, a creek, a ride through someone's living room and a brewery.
Countering Doubts with Pure Stoke
Ambassador Ben Popper shares his experiences from the 2018 Rock Cobbler, where he first got introduced to his fellow gravel ambassadors and dove head-first into his first gravel event of the year after a cold winter in Seattle.
"When you've made a commitment to bring the party to the entire course, you can't stop early."
Ben Popper's foolproof training plan for the Almanzo 100, set to take him straight from the couch to conquering 160km of Minnesota's finest gravel roads through the small town of Spring Valley.

What is a Gravel Bike?
Any bike can be considered a gravel bike, whether it was sold as a road, cyclocross, mountain, or gravel bike. But distinct characteristics and components have helped define the new category, making bikes more capable and more fun to ride on mixed surface terrain.
Any bike can be considered a gravel bike, whether it was sold as a road, cyclocross, mountain, or gravel bike. But distinct characteristics and components have helped define the new category, making bikes more capable and more fun to ride on mixed surface terrain.
Most dedicated gravel bikes have drop handlebars and, from a distance, they resemble a road or cyclocross bicycle. They often use disc brakes, clutch-equipped rear derailleurs, and dual-sided SPD mountain bike pedals. Most gravel bikes also offer clearance for bigger tires, additional water carrying capability, a more compliant construction, and longer, lower geometry for stability on rough roads.
Disc Brakes
Disc brakes deliver all-weather stopping power and superior modulation for all riding conditions. They also open up frame designs, allowing for wider tires while maintaining superior mud clearance when the roads get soggy.
SPD Pedals
Some gravel riders prefer road clipless pedals and shoes but most opt for efficient mountain bike shoes and dual-sided, SPD pedals. Mountain bike shoes offer additional grip for tricky gravel hike-a-bikes and creek crossings. Shimano’s SPD mountain bike pedals also provide reliable engagement and release in even the muddiest of conditions.
Clutch Rear Derailleurs
Shimano developed the first clutch rear derailleur for mountain biking and now brings its Shadow Plus technology to the gravel scene with its Ultegra RX rear derailleur. It delivers reliable shifting even during bumpy sections of a tough ride. The Ultegra RX derailleurs also offers a quieter drivetrain, allowing you to focus on the ride.
Wider Tires
For maximum speed, comfort, and control on loose, inconsistent surfaces, most gravel riders look to tubeless tires with a variety of tread patterns in widths from 32 to 45mm. Some go even wider, opting for 29er or 650b mountain bike tires sizes.
Frame Geometry
Longer wheelbases help with tire clearance while also offering a smoother ride. Lower bottom brackets lend stability and confidence-inspiring handling. All these features combine to tame the fatiguing effects of riding gravel, allowing you to ride farther and faster.
Extra Bottle Mounts
With the remote nature of many dirt roads, the ability to carry an extra water bottle or two makes the riding more fun. Instead of worrying about the next convenience store, you can explore further.
Frame Compliance
Whether your gravel rides are all-day epics or quick local jaunts, all of us can appreciate a more comfortable ride. Many gravel bikes are made with design features that help take the edge off the road. Suspension has also started to creep into the gravel world in the form of soft-tail frames, forks, stems, and seat posts.
