Gravel bikes are one of the fastest growing sectors within cycling and picking up a second hand gravel bike is a great way of experiencing one of the most versatile styles of bike ever created. A gravel bike differs from a road bike and even a cyclocross bike by having the clearance to run very wide tyres suited for going both on and off-road and more relaxed geometry - making them incredibly fun to ride. Handlebars tend to be wider and shaped to offer more confidence when riding down hills off-road. Most have the ability to fix numerous bottle or cargo cages alongside rack and mudguard mounts, making them very popular with riders wanting to start bikepacking.

When looking for a second-hand gravel bike, here are some key things to consider:

Frame condition: Check the frame for any cracks, dents, or signs of damage. Small scratches and scuffs are normal, but significant damage to the frame could compromise the structural integrity of the bike.

Tires: Look at the tire condition and ensure that they are suitable for gravel riding. Gravel tires should be wider with thicker tread patterns than road bike tires.

Brakes: Check the brake pads for wear and make sure they are functioning properly. Look for any damage to the brake discs or calipers.

Drivetrain: Inspect the gears, chain, and derailleur. Make sure the gears shift smoothly and there is no slipping or skipping. Check the chain for wear and rust.

Handlebars: Ensure that the handlebars are suitable for gravel riding. Drop bars are common on gravel bikes, but flat bars are also used.

Fit: Make sure the bike fits you properly. Sit on the bike and check the handlebar and saddle height. Make sure the bike is comfortable and easy to control.

Accessories: Check if the bike comes with any accessories, such as a saddlebag or bike lights. This can save you money in the long run.

History: Ask the seller about the bike's history, including how often it was ridden and how it was maintained. A well-maintained bike will be more reliable and have a longer lifespan.

Price: Finally, consider the price. Compare the asking price to the original price of the bike and the condition of the bike. Don't be afraid to negotiate the price if you think it's too high.
