Why you should buy a road racing bike — plus 5 of the best

Bikes for going fast are the best fun you can have on two wheels

[This article was last updated on October 2, 2020]

If you like to go fast, then you want a proper road racing bike. Here’s why.

It’s a sunny afternoon in May and I’ve just slogged my way up an Italian mountain. I enjoy climbing, but I’m a long, long way from being good at it, though the light carbon fibre bike I’m riding really helps.

But now comes the good bit, a long descent that starts twisty and ends in a die-straight road on glass-smooth Tarmac through a tunnel and into Trento. I start by screaming round the curves, leaving behind the riding companions who waited for me at the top. I’m tucked deep, weight on my outside foot, banking hard into the hairpins, aiming for the smoothest line through the apex, using the whole road to hold my speed.

I’m doing 80 km/h when I hit the tunnel and my Garmin loses signal. I glimpse a roadside speed warning showing a number that starts with 9 as I plummet. Thanks to a tailwind I’m suspended in a bubble of silence as the walls rush by. Rock-solid stable under me, my bike is the only thing stopping me becoming an untidy smear on the blacktop. It’s glorious.

Moments like this are why I adore road racing bikes. The handling and cornering accuracy of a good race bike make it the most fun bike you can ride if you love to go fast.

What makes a race bike?

Let’s be clear: we’re talking here about bikes intended for racing. That means low handlebars, long top tube, and a flat-back, stretched position. Combined with the typical geometry of a race bike — 73-74° seat and head angles and short chainstays — these are bikes that feel quick, respond quickly but predictably to steering, but are still comfortable all day, as long as you’re flexible enough to handle the position.

It’s the ride and handling I’m talking about here. Other features you’ll typically find on an elite racer’s bike are optional. Not everyone can get all the way down to the bar position produced by a long stem, slammed all the way down, for example, but a low bar puts your weight over the front tyre and helps with adhesion and handling.

Similarly, you’ll find the gears on an elite bike biased to the high end, with a 53/39 chainset and more than likely an 11-25 sprocket cassette. That’s fine if you’re very fit or in the Fens, but there’s no shame in going for a compact, 50/34 chainset or wider sprocket range. Even the pros have been known to use compacts and the latest version of Shimano’s pro-grade Dura-Ace groupset offers an 11-30 cassette.

Some other things are vital though. Race bikes have either very light light wheels, or, even better, aero deep-section rims. Light wheels add a bit of speed on hills, just by lightening the whole bike, but aero wheels add speed everywhere, which far outweighs the disadvantage of their extra weight.

A light, stiff frame is also a must, so you’re looking at aluminium, carbon fibre, titanium or one of the more exotic steel alloys like Reynolds 931 or Columbus Spirit. If weight matters to you — and if you’re considering a race bike it probably does — then carbon fibre is your likely choice as even the best metal frames still give away a couple of hundred grams to composites. But metals still have their merits. For very tall riders, a large-tubed aluminium frame can be usefully stiff while still light, and the characteristic zing and spring of steel and titanium means they have plenty of fans.

Traditionally, race bikes have used side-pull caliper brakes at the rim to stop, but you now have other options. Shimano’s Direct Mount brakes are a caliper brake with a firmer mounting that comprises a pair of bosses on the frame or fork. Direct Mount rear brakes are often tucked under the chainstays for a cleaner look.

But the big news in brakes of the last few years is discs, and since cyclesport's governing body the UCI dropped its ban on disk brakes they're now everywhere. Many top-end bikes are only available now in disc-braked configuaration.

What are race bikes good for?

In short: going fast. That includes racing, of course, but you don’t need to race to enjoy riding a race bike, you just need to enjoy adding the ‘swish’ of a finely-tuned bike to the sounds of the countryside.

These bikes are good for any riding where speed is the aim, then, and that can include fast commuting, especially if you’ve a long way to go. Your options for carrying stuff are pretty much limited to a rucksack (or ‘bikepacking’ bags,see below) but if you choose carefully you’ll be able to find a bike that will take 25mm tyres and low-profile mudguards like Crud Road Racers or SKS Raceblade Longs, so at least you’ll get a dry bum as well as a few extra minutes in bed.

What about multi-day riding? With the right bags, and maybe a change of gearing to compensate for the extra weight, a race bike makes a great fast tourer. However, there are no rack attachment points on most race bikes, and it’s almost certainly a bad idea to bodge one on to a lightweight frame. You’d be adding loads that the frame’s not designed for, and the short back end of a race bike means you won’t have heel clearance anyway.

Apidura Saddle Pack

The better option is to look at the gear used by unsupported ultra-distance racers. For events like the TransContinental Race, riders carry the bare minimum of possessions in a large saddlebag, sometimes supplemented by a bag in the frame or a handlebar bag. This set up works really well if you’re staying in hotels or B&Bs (or sleeping in bus shelters, TransCon style) and the bag being in line with your body means it doesn’t affect your aerodynamics as much as panniers.

Five great race bikes

There’s a huge variety of race bikes to choose from, and a vast price range. To give you a flavour of what’s out there, here are five great bikes, covering the price range from very reasonable to “you could get a car for that!”

Specialized Allez E5 Sport 2021 — £949.00

2021 Specialized Allez Sport

For the latest edition of their entry-level race bike, Specialized softened the Allez a touch, raising the front end, slackening the angles and adding mudguard mounts, but managed to do this without losing the Allez's fun and appealing ride.

This is a bike that'll help you out if you've had a challenging day and need to blow off some steam; you can stamp on the pedals and really go for it.

It's an exciting bike to ride and you'll easily get that little adrenaline giggle when you really push it. If you're confident, you can definitely take a few risks.

Van Rysel RR 920 CF — £1,999.99

2020 van rysel rr 920 cf black ultegra

The Van Rysel RR 920 CF is built around Decathlon's Ultra Evo Dynamic frameset, which in a medium size has a claimed weight for the frame of 850g and just 320g for the fork. Hung with an Ultegra groupset and Mavic Cosmic Pro Carbon wheels that makes the RR 920 CF a bargain super-light bike.

When he reviewed the B’Twin Ultra 900 CF 105, which used the same frame, our Stu Kerton said: "The handling is sweet. The head angle is 73 degrees, which isn't massively steep for this kind of bike, but it's enough to keep the front end quick and precise without instilling any form of twitchiness. The Ultra CF is a fun, quick-handling machine to ride, no matter what your level of ability; it flatters."

 Specialized Tarmac SL6 Comp 2021 — £3,200.00

2021 specialized tarmac sl6 comp

We loved this bike’s 105-equipped kid brother, and like that bike this is a smart-looking and well-packaged bike that offers the sort of fast and engaging ride that will suit budding racers.

The position and ride is what you would expect from a race bike; it strikes a good balance and is very accommodating of new cyclists as it is to experienced racers.

Like previous generation Tarmacs it’s easy to live with. There are no handling quirks, it's very predictable and you feel right at home very easily. This is a bike that can equally be ridden all-day long in comfort, booted around a tight and twisty criterium circuit, ridden to work, used on the chaingang, or just lazy Sunday morning rides to the coffee shop. It's happy pootling or going flat out.

Cannondale CAAD13 Force eTap AXS — £4,799

2020 Cannondale CAAD13 Disc Force

There are few brands as synonymous with aluminium as Cannondale, with its fabled CAAD – 'Cannondale advanced aluminium design' – series. The US company built its reputation on aluminium frames, and even though it has invested heavily in carbon fibre in more recent years, it remains fully committed to aluminium in a way few brands are.

The CAAD13 is a finely honed bike with a level of comfort and refinement that makes you wonder why you would buy anything else, and certainly wonder why aluminium lasted such a short time as the cutting-edge of racing bicycle technology back in the 90s. It's so smooth that it outshines many carbon fibre road bikes we've tested over the years. It's nothing short of marvellous.

Trek Émonda SLR 9 2021 — £9,700

2021 Trek Émonda SLR 9

The Émonda series is Trek's line of lightweight race bikes and for 2021 it's had a major revamp with improved aerodynamics and new carbon fibre technology that Trek says keeps the frame weight under 700g for the SLR version. That's light.

Trek says the new Émonda is aerodynamically optimised for climbing, rather than for the usual 40km/h aero bike makers tend to cite. That means that if you love to ride in the mountains, this could be the perfect bike for you.

Acknowledged by the Telegraph as a leading cycling journalist, John Stevenson has been writing about bikes and cycling for over 30 years since discovering that people were mug enough to pay him for it rather than expecting him to do an honest day's work.

He was heavily involved in the mountain bike boom of the late 1980s as a racer, team manager and race promoter, and that led to writing for Mountain Biking UK magazine shortly after its inception. He got the gig by phoning up the editor and telling him the magazine was rubbish and he could do better. Rather than telling him to get lost, MBUK editor Tym Manley called John’s bluff and the rest is history.

Since then he has worked on MTB Pro magazine and was editor of Maximum Mountain Bike and Australian Mountain Bike magazines, before switching to the web in 2000 to work for CyclingNews.com. Along with road.cc editor Tony Farelly, John was on the launch team for BikeRadar.com and subsequently became editor in chief of Future Publishing’s group of cycling magazines and websites, including Cycling Plus, MBUK, What Mountain Bike and Procycling.

John has also written for Cyclist magazine, edited the BikeMagic website and was founding editor of TotalWomensCycling.com before handing over to someone far more representative of the site's main audience.

He joined road.cc in 2013 and these days he lives in Cambridge where the lack of hills is more than made up for by the headwinds.
