Gravel bike buyer's guide
Adventure begins here
From your first mile off pavement to your five-hundredth, gravel riding ignites something inside us that’s hard to tap into anywhere else. Whether you’re pursuing quiet miles away from town, far-off scenic horizons filled with laughter and friends, a new physical challenge, or something else entirely, we’ve got you covered with all the knowledge, bikes, and gravel gear you need to explore what’s waiting for you down the road less traveled.
What is gravel riding?
What is a gravel bike anyway?
Gravel bikes are multi-surface bicycles built to explore millions of miles of unpaved roads that roll on long after the pavement ends. They find the balance between the off-road capability of a mountain bike and the quick-rolling, lightweight feel of a road bike, giving you every benefit you need to explore far beyond the pavement.
Anatomy of a gravel bike
1. Long, stable geometry
Gravel bikes typically feature a longer wheelbase that helps elevate stability in rough terrain, and a slightly more open cockpit to boost comfort on long rides.
2. Tire clearance
To give you a boost of traction and comfort, gravel bikes typically offer more clearance for higher-volume (38c-45c), knobbier tires than those used for road bikes
3. Mounts for bags & cages
Gravel rides can take you far away from resources like water, bikes shops, and even cell service, so many gravel bikes come with mounts for cages, racks, and bags that let you load up with all the essentials you might need for the long-haul. Some even feature internal frame storage for stashing tools and gear!
