First Look: B'Twin Triban 540

Sleek and nippy flat bar road bike strikes a balance between speed and practicality

Road bikes are lots for fun for sunny days zooming round the lanes and belting to the office, but not everyone likes drop handlebars. B'Twin's Triban 540 promises that road bike zip with the more upright position of a flat bar so you can sit up and admire the view or keep an eye out for random taxis.


New tube shapes, low-key colour scheme and tidy welding

Part of the bike range at sport store chain Decathlon, the £500 B'Twin Triban 540 strikes a balance between speed and practicality. On the speed side, well, at heart it's a road bike. Skinny tyres, narrow saddle, seat a bit higher than the bars. On the other hand, it's got a flat bar, with gears controlled by mountain bike-style triggers so you never need move your hands away from the brakes.

Find the B'Twin Triban 540 at Decathlon.


25mm tyres from Hutchinson have a smooth tread pattern for speed

The Hutchinson Equinox tyres aren't super-skinny at 25mm, and there's room in the frame for fatter rubber for more grip and comfort. There's also space and the necessary mounting points for mudguards and racks, so the Triban 540 can be used for a spot of light touring too.

If you want a comfier ride there's room in the frame for fatter tyres. It'll take tyres up to 32mm wide without mudguards, or 28mm with them, which should make it an ideal fast pothole-basher too.


Shimano's Tiagra trigger shifters come easily to hand

Its versatility makes a bike like this especially attractive. You're not going to race it, but there's no reason you couldn't do a shorter sportive on the Triban 540. As well as the road applications we've already mentioned, you could also use it on dirt roads, though you'd definitely want to fit the fattest tyres you can fit for that.

Hybrids tend to be a bit weighty, but at a claimed 9.3kg (20,4lb) without pedals, the Triban 540 is a respectable weight for a £500 bike. That's down to the aluminium frame, which Decathlon claims weighs 1.9kg (4.2lb) in a size 57cm, carbon fibre fork and sensible selection of components especially the Shimano Tiagra transmission.


The combination of 50/34 compact chainrings and 11-28 sprockets gives a wide range of gears for the hills

Tiagra sits in the middle of Shimano's line-up. It's good stuff — reliable, easy to use and nicely styled.

Decathlon have gone for a double chainset to keep things simple. It's a compact configuration so you won't be struggling on hills with the kind of high gears only a pro racer can turn. Rather, there's a wide gear selection that covers the range from zooming down hills to getting back up them without having to toil too much.


The aluminium frame is newly designed for the Triban 540 and its stablemates

First riding impressions are good. The gears click easily into place, and our tester reports the climb of Bristol's ominously named Two Mile Hill on his journey home is a lot easier than on his previous bike.

He also likes the upright riding position, and is even finding the toeclips easy to get used to.


Plenty of room for fatter tyres and mudguards thanks to the long-reach brake calipers

The Triban 540 is one of four new models in Decathlon's range that we looked at when they were launched in May.

All four use the same new 6061 aluminium frame and carbon fibre fork. The frame has all-new tube profiles, with a rounded square shape, and a larger down tube. The geometry has been updated too. The new Tribans have been designed less for racing and more for those cyclists wanting a versatile and comfortable bike for tackling sportives or riding to work.

The fork has fittings midway down the blades for a low-rider front rack. You can carry even quite large panniers in this position and they'll affect the ride and handling less than if they're on the back. This was the set up used by adventurer Nick Sanders when he rode round the world in 80 days back in the late 80s.


Our tester is finding the own-brand saddle is a comfy place for his bum

As we've come to expect from Decathlon, the Triban 540 is great value for money. The Shimano Tiagra components are of a quality usually found on road bikes up to around £1,000, so to find them on a £500 bike is a real bonus. That's partly down to a flat bar not needing expensive STI brake/shift levers, but largely down to Decathlon's huge buying power and the fact that there's no distribution layer in the chain between you and the factory.

For riders who shy away from drop handlebars, the Triban 540 would be a great first 'serious' bike or a step up from the kind of budget hybrids we looked at in our guide to cheap transport recently.

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.

Along with road.cc founder Tony Farrelly, 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. He lives in Cambridge where the lack of hills is more than made up for by the headwinds.

Hello

 

new member,  ridden various hybrids daily for a few years but have become fed up with slow, heavy bikes so I've been looking for a faster, sleeker alternative & considered plenty of drop bar road bikes

 

however, as a large 48 year old with a dodgy back I've never felt comfortable at the thought of those riding positions so to find a flat bar road bike of this quality at this price is great news and I'm ordering it tomorrow

 

may encourage me to get out and explore the Norfolk countryside and get fitter having fun as well as being able to cut commuting time down considerably with probably less effort

 

will report back when I've been riding it a month

My first modern bike was a flat bar Ridgeback Flight. 105 3x9-speed. Loved it, but then got the drop bar bug. Never looked back.

It's a great place to start your journey and a lot of fun to ride.

I bought an earlier model about 7 years ago in France (Decathlon weren't in Scotland at that time). Still going strong and still a favourite despite my stable of Genesis bikes. Best £300 I ever spent.

I'm guessing they can only test what they get sent in.

You might be right. The others would surely be missing a trick, if so. Or perhaps they're worried they mightn't stack up so well...

More to the point.
Why aren't other manufacturers trying to match them in the value for money stakes?
If other manufacturers got their act together maybe there would be a greater diversity of bikes reviewed on Road.cc.

The ball is very much in their court.

They sell direct to consumer so one would hope that they're good value

Its a fine bit of kit, I had a go on one of these before I plumped for the 520 drop bar. For the money, you can't go far wrong I reckon  41
