How To Clean A Road Bike Chain And Gears

Trying to decide between a mountain bike vs road bike? We're here to help. Bikes have never been so specialised in terms of the terrain they're designed for, so it's essential you make the right choice of steed for where and how you plan to ride.

There are certain essential differences between road and mountain bikes that you need to be aware of, and the new niche of gravel biking has added to the potential pitfalls faced by first-time buyers. Read on for a rundown of the differences between the two bike breeds, and once you've figured out which is the right choice for you, head to our best mountain bike or best road bike guides for some product recommendations.

Mountain bike vs road bike: suspension

A mountain bike can vary from having no suspension to sporting front suspension or being a 'full susser' with both front and rear suspension – the more rugged the terrain you ride the more suspension you're likely to need.

A road bike usually has no suspension; that said, some higher end road bikes may offer a small amount of suspension both front and rear, and the whole thing is further complicated by gravel bikes, which look like beefed up road bikes and are used for riding dirt roads – they may have a limited amount of suspension in, for example, the seat post.

If you plan to ride entirely on road you probably don't really need any suspension; for anything else, it's definitely worth considering having something to soak up the bumps.

Mountain bike vs road bike: frame

Mountain bikes with full suspension have different frame shapes and geometries than road bikes in order to accommodate the rear suspension, otherwise, road, mountain and gravel bikes appear to have pretty much the same frame shape at first glance.

However, subtle variations in the geometry of the frame mean that mountain bikes frames give a more upright riding position for better handling on tricky terrain, whilst road bike frames provide a more 'stretched out' riding position for improved efficiency and aerodynamics.

It's also essential to consider frame size; your local bike shop will be able to measure you up to ensure you have a correctly sized frame – too small or too large and you'll find the bike uncomfortable and unwieldy to ride.

Mountain bike vs road bike: handlebars

Flat, wide bars for mountain bikes, narrower drop bars for road bikes is the rule. Flat, wide bars give a more upright and stable riding position, which is better for manoeuvring a bike over rough terrain, whilst drop bars offer a lower and more efficient riding position along with a wider variety of hand and body positions, which helps prevent fatigue on long road rides.

As ever, gravel bikes muddy the waters by offering a choice of flat, drop or 'flared' bars – the latter are drop handlebars with a slight flare in the drop, which gives a wider grip for better handling off-road.

Mountain bike vs road bike: pedals

Road, mountain and gravel bikes may come with either flat or clip-in pedals. 'Flats' will usually have raised pins on the upper surface, which help the soles of your shoes grip when riding on rough terrain; flat pedals on road bikes won't have such aggressively shaped pins as they do on mountain bikes as there's less need for grip.

Clip-in pedals allow cleats attached to the bottom of your cycling shoes to literally 'clip-in' to the pedal, providing a more efficient pedal stroke – but they take a bit of getting used to and you need to have them set up correctly so you can clip in and out quickly and efficiently – it's especially important to master unclipping from the pedals otherwise if you wipe out you'll hit the deck still attached to your bike.

Mountain bike vs road bike: tyres and wheels

Road bikes have narrow, smooth tyres, mountain bikes have wide, knobbly tyres. That said there's an almost infinite number of combinations of tyre widths and tread patterns for both road and mountain bikes depending on the terrain and the season (eg road bike tyres have a more grippy and potentially wider tread for wet winter conditions than they do for dry summer roads, and mountain bikes tyres have different tread patterns for muddy trails (wider and more knobbly) than they do for dry trails (narrower and less aggressive tread)).

Gravel bike tyres fit somewhere in between with less knobbly, narrower tyres than full-on mountain bikes but more rugged, wider tyres than a road bike.

Tubeless tyres are becoming increasingly popular on all types of bicycle; they don't have inner tubes but instead contain a sealant which automatically seals small punctures, whilst larger punctures can be quickly repaired on the go by the insertion of a repair 'plug'.

Road bikes have 28" (aka 700c) diameter wheels; mountain bikes may have 27.5" (or 650b) or 29" diameter wheels and gravel bikes can be either 28"/700c or 27.5"/650b. Confusing? Yes, a little, but essentially bigger diameter wheels roll more efficiently whilst smaller diameter wheels provide better handling.

The width of the tyre is also important – put simply, the wider it is the more it soaks up bumps but the less efficiently it rolls.

A good bike shop will guide you through all the above when choosing a bike, which until the advent of gravel bikes was relatively straightforward i.e. you ride a road bike on roads and a mountain bike everywhere else.

Gravel bikes can do a little of both but are not as good for pure road riding or full-on mountain biking, so your choice of bike should be dictated by whether you intend to specialise in tarmac, dirt or fancy a bit of both. Life is never simple, hey?
