Confused by all the choices in your local bike shop? We're here to help

If you’re just getting into cycling, one of the biggest sources of confusion is the jargon around bike types. We’re here to help you tell the difference between road racers, sportive bikes, cyclo-crossers and more.

Along with the bike boom of the last decade there’s been a boom in the types of bike on offer as the bike industry tries to offer us bikes that are just right for the wide range of riding we do. You can ride and have a great time on just about anything, but if you’re shopping for a bike it’s handy to know what the different types are best at.

Road racing bikes

Sleek, stripped-down and as light as possible, these are bikes intended for racing on the road (the clue’s in the name) in events where riders start together. They feature close-ratio gears; skinny tyres, usually 23mm or 25mm wide; and drop handlebars.

Even if you don’t race, blasting down the road on one of these, sharp, purposeful bikes can be lots of fun. On a sunny July afternoon you can pretend you’re climbing the Tourmalet in the Tour de France even though you’re really on Box Hill

High-end road racing bikes, especially those used in professional racing, have frames made from carbon fibre composite to reduce weight. Frames may also be made from titanium, aluminium and steel, each of which has its own characteristics that give rise a frame’s feel.

Road bike wheels are a size known as 700C, a name that comes from a French system that’s otherwise largely disused. What you need to know is that this is the almost-universal size for adult road bike wheels.

Road racing bikes have one of three tyre types. Clinchers are the most common. They have a wire bead that engages with a hook on the rim to hold them in place and have a separate inner tube. Tubeless tyres are similar but the air is held in place by a rubber coating on the inside of the tyre, a sealing strip in the rim and sometimes a liquid sealant. Tubular tyres have the tyre casing sewn around the inner tube and are held on a special rim with glue.

The brakes on road bikes act on the rims as discs are not yet allowed in racing and those rims will often have a deep-section shape for aerodynamics.

Cutting through the air is also the objective of the riding position on a road racing bike which usually features a substantial drop and reach from saddle to handlebar. However, you do need a bit of flexibility for this position to work for you.

There’s a widespread belief that road racing bikes are uncomfortable, but that’s not the case if they’re set up properly. After all, professional racers sit on these bikes for three weeks in the Tour de France, which wouldn’t be possible if the bikes were agonising. However, it’s unarguable that the skinny high-pressure tyres of a road racing bike can transmit plenty of road vibration to the rider. As a result, these bikes work best on smooth roads.

Sportive bikes

A sportive bike is a rather softer version of a road racing bike, intended to improve comfort for riders taking part in one-day challenge events. Sportive bikes therefore usually have a more upright riding position, achieved with a longer head tube and shorter top tube.

These are still road bikes, but since sportive road surfaces are often poor, they’ll accommodate wider tyres than a race bike for better grip and comfort, and some have mounts for mudguards so you don’t get soaked if the weather turns wet.

Because they’re not intended for racing, sportive bikes can have disc brakes for all-weather control, and many do. Some also have features intended to absorb road vibration, such as Specialized’s Zertz inserts and Trek’s Isospeed decoupler.

Sportive bike gearing tends to be lower than on road racing bikes. Rather than a race bike’s 53/39 chainrings, you’ll usually find a 50/34 compact chainset, and bigger sprockets at the back too.

You’ll find the full gamut of frame materials in sportive bikes, from custom steel and titanium to lightweight carbon fibre and aluminium.

Aside from riding position and the details discussed above, sportive bikes have many features in common with road racing bikes, including 700C wheels, clincher tyres, narrow saddles and drop handlebars.

Touring bikes

Packing your possessions into panniers and pedalling away is a great old cycling tradition; touring bikes have developed to make it easy to get away from the 9-5 on your bike.

The obvious defining features of a touring bike are pannier racks to carry your luggage, or at the very least a rear rack, and mudguards to keep you dry if it rains. Accommodating those, and fatter tyres (at least 32mm wide) to help carry the weight, means the frame will be longer and gappier.

That in turns means the caliper brakes on road racing and sportive bikes won’t reach the rims, so touring bikes have traditionally used cantilever brakes. Modern touring bikes often have disc brakes, which solve the same problems and improve braking.

With a shorter top tube and longer head tube, touring bikes have a more upright riding position.

Touring is one area of cycling where steel is still a common frame material. Tourists value its springy feel and durability. For those with dreams of long-distance expeditions, it has the advantage of being easily repaired; you can’t get a heat-treated aluminium frame welded by a garage mechanic in eastern Kyrgyzstan.

So that you can keep riding with a full load however steep the road gets, touring bikes have the lowest gears of any category of road bike. Ratios below 1:1 aren’t unusual, and tourists often modify their bikes to get even lower.

Cyclo-cross bikes

Cyclo-cross is the winter cycling discipline of off-racing on drop-bar bikes with fatter, knobby tyres on short courses, usually in locations such as municipal parks. It involves a mix of surfaces and obstacles such as low barriers, steep run-ups and sand pits. And mud. Lots of mud.

Cyclo-cross bikes intended for racing are therefore a bit higher off the ground than road bikes and have lots of clearance around the tyres for mud. They usually have disc brakes since they were allowed in cyclo-cross a few years ago, but there are still plenty around with cantilever brakes.

Gearing is usually close, with 46/36 chainrings for fast, hassle-free shifting. Some racers have always used single chainrings and that’s becoming a more common option as single-ring technology crosses over from mountain biking.

The ability to run very low pressures with less chance of a pinch flat means tubular tyres are still popular for cyclo-cross, though off-the-peg bikes usually have clinchers. Racing equipment rules limit tyre width to 33mm, presumably to stop cyclo-cross bikes turning into drop-handlebar mountain bikes.

Steel and titanium are still used occasionally for cyclo-cross bikes, but the need to keep the bikes light so they can be carried in running sections means aluminium and carbon fibre dominate.

In the last few years many riders have realised that a cyclo-cross bike’s ability to accommodate wider tyres makes it a great round-town pothole-basher. That’s led to ‘soft’ cyclo-cross bikes with mounts for racks and mudguards and less racy gears. With a change of tyres these bikes can tackle anything from a sportive to dirt roads to your first cyclo-cross race.

Gravel/adventure bikes

Part cyclo-cross bike, part sportive bike and part touring bike, the emerging category known as gravel bikes or adventure bikes might just be the most versatile drop-handlebar bikes around.

The distinguishing features of gravel bikes are room in the frame for very fat tyres, and a riding position and handling that’s not as racy as a cyclo-cross bike’s. That means they’re great for riding dirt roads and less technical trails, but they’ll also roll along happily on the road too, and they point and laugh at potholes and crummy road surfaces.

Versatility is a vital part of the concept, so gravel bikes will accommodate racks and mudguards. You can use them for commuting and even light touring, though few have the low gearing of a purpose-made touring bike.

That said, you do get wide range gearing on gravel bikes, just not quite as wide as a touring bike’s.

With no silly equipment rules or influence of tradition, gravel bikes universally have disc brakes.

They’re usually made from aluminium or carbon fibre for light weight, though there are steel variants and Litespeed has recently launched a titanium gravel bike frame.

While gravel bikes currently use standard road bike handlebars and other components it’s a safe bet that as this class of bike develops we’ll see changes in areas like handlebar width and shape and gearing. This year, we’re already seeing gravel bike manufacturers trying SRAM’s combination of a single chainring and a wide-ratio cassette.

Mountain bikes

Designed for riding on rocky, steep trails, mountain bikes have wide, flat handlebars; fat, knobby tyres; low gears for climbing; powerful disc brakes and usually suspension on the front or both wheels.

There are numerous types of mountain bike including long-travel dual suspension bikes for downhill racing; hardtails with suspension forks for general trail riding; fat bikes with low-pressure, super-wide tyres; go-anywhere dual suspension trail bikes and short-travel bikes for mass-start cross country races.

There are three wheel sizes: 26-inch, 650B (aka 27.5-inch) and 29-inch, in increasing order of size. If you want to see a heated argument about the merits of the different sizes, see every third thread in every mountain bike forum for the last ten years. In summary: big wheels roll better, smaller ones are more manoeuvrable and beyond that it’s a religious issue.

During the mountain bike boom of the late 1980s and early ’90s mountain bikes were incredibly popular as urban transport. Riders liked their comparatively powerful brakes, robust fat tyres and upright riding position. Many are still out there.

Hybrid bikes

They don’t get much attention from the cycling media, but as a result of their practicality hybrids are actually the UK’s best-selling bike style. As the name suggests these bikes have features taken from road bikes and from mountain bikes. From road bikes they have light frames and large, 700C wheels. From mountain bikes they get flat handlebars and cantilever or disc brakes. The larger wheels make them nippier round town than mountain bikes.

The tyres are usually in between road and mountain bike width, which helps make a hybrid more comfortable, better able to handle potholes and capable of tackling easier off-road tracks and trails.

Hybrids are almost always made from aluminium for its combination of strength and low weight. They sometimes have suspension forks, which are arguably a bit of a gimmick, adding weight and cost without adding much useful function.

They always have mounts for rack and mudguards, and some models come with them already fitted. Hybrids intended for the European market may also have lighting systems powered by a dynamo built into the front hub, so you never run out of batteries, and a frame-mounted lock on the rear wheel.

Folding bikes

Want to store a bike in a tiny London flat, or take one on a peak-hour train as part of a bike-train-bike commute? You need a folder. As the name suggests, these are bikes that fold, but modern folders are a long way from the hinged Raleigh 20 of the ’70s.

A top quality folder, such as a Brompton or Birdie, folds in seconds into an easily-carried or stashed package. That means you can probably also store it under your desk at work, rather than leaving it out to risk getting stolen.

Folding bikes generally have steel or aluminium frames and small wheels. You sacrifice some ride comfort for the convenience of folding, but better folders deal with that by including suspension.

Our official grumpy Northerner, John has been riding bikes for over 30 years since discovering as an uncoordinated teen that a sport could be fun if it didn't require you to catch a ball or get in the way of a hulking prop forward.

Road touring was followed by mountain biking and a career racing in the mud that was as brief as it was unsuccessful.

Somewhere along the line came the discovery that he could string a few words together, followed by the even more remarkable discovery that people were mug enough to pay for this rather than expecting him to do an honest day's work. He's pretty certain he's worked for even more bike publications than Mat Brett.

The inevitable 30-something MAMIL transition saw him shift to skinny tyres and these days he lives in Cambridge where the lack of hills is more than made up for by the headwinds.

Is there a good reason why you should call cyclo-cross bike a "gravel/adventure bike" other than marketing?

I don't see any noticable difference... Call me old fashioned.

It's like the difference between road racing bikes and the sportive bikes

True CX bike is a racing machine, it's not about a comfort. Gravel bike give you ability to use wide tyres. Also their geometry is more relaxed.

So you can call gravel bikes like "comfort CX bikes"

 

P.S. Some (lot?) of CX bikes a few years ago wasn't a true CX bike, they has mudguards holes, tyres clearance etc. So they actually were gravel bikes and those vendors just rename that models
