The ultimate guide to gravel bikes – Trek bikes

From your first mile off tarmac 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 travelled. 

Gravel riding is a versatile style of cycling that fits neatly between road and mountain biking. It takes you off the beaten track over miles of multi-surface, unsurfaced and rough roads. While it’s referred to as gravel riding, you’ll find that sturdy gravel steeds are eager to explore everything from dusty rail trails to steep and rocky fire roads – or even on wooded singletrack, if you dare.

What is a gravel bike anyway?

Gravel bikes are multi-surface bicycles built to explore the millions of miles of unsurfaced roads that roll on long after the tarmac 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 tarmac.

Anatomy of a gravel bike

1. Comfortable upright
geometry

Gravel bikes often feature a more upright riding position to keep you confident and a slightly more open cockpit to help boost comfort on long rides.   

2. Tyre clearance 

Gravel bikes typically offer more clearance for higher-volume (38 – 50 mm) tyres that are knobbier than those found on road bikes to give you a boost of traction and comfort.

3. Mounts for 
bags and cages 

Gravel rides can take you far away from resources like water, bike shops and even mobile phone 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!

Types of gravel surfaces

All-road

A little bit of everything. Smooth tarmac, rough road surface, rugged cobbles and light gravel. Bikes for all-road riding should accept tyres from 32 to 38 mm wide.

Gravel

Roads and paths with mixed surfaces ranging from hard-packed dirt to deep, loose gravel and dusty, rocky terrain. Gravel riding is best done with tyres from 35 to 50 mm wide.

Whatever the kind of gravel surface you ride or the goals you’re chasing, we've got you covered with gravel bikes for every kind of gravel riding and terrain.

Tyres are a surprisingly personal choice for your bike and choosing the right ones will help you have the most fun on every gravel ride. From puncture-protection to grip and size, many factors play a role in your perfect tyre choice.
