A sneak peek at Decathlon’s 2019 disc-braked Triban bikes, plus 2018 performance bikes in carbon and aluminium

The future is coming and it’s got disc brakes at very reasonable prices

Decathlon has revealed plans for new bikes and accessories, including two new disc-braked models in the popular Triban range, plus updates to the sporty aluminium and carbon fibre Ultra bikes. We popped over to the launch in Barcelona to take a look.

When you design and spec your own bikes, have literally hundreds of stores around the world, and are determined not to simply put your decals on other people’s designs, you have to plan new models well in advance. Your Treks and Specializeds are thinking well into the future too, but they keep their plans very close to their chests, whereas Decathlon is cheerfully open about its goals, which include becoming a very big player indeed in the global cycling scene.

Of the bikes unveiled in Barcelona, the two most likely to move Decathlon toward that goal are the new Tribans that will hit Decathlon stores around September. Let’s look at those first.

Bye-bye B’Twin, hello new Tribans

From the end of this year, Decathlon will start to phase out B’Twin as a bike brand. A new name for the sportier bikes has yet to be decided, but the popular entry-level Triban bikes will now simply be known as Triban, without the B’Twin handle.

The Triban Adept will replace the current Triban 520 and will have disc brakes, a new aluminium frame, clearance for 42mm tyres, eyelets for racks and mudguards and a wide-range gear set. It’ll cost £550-£600 and sounds like a sure-fire hit among commuters.

The Triban Adept Plus will have the same frame with a fit-out centred on Shimano 105 with HY-RD brakes, and will cost about £750.

Both new Tribans will have Decathlon’s own puncture-resistant tyres and tubeless-ready Triban wheels, along with a new saddle, and a clever handlebar stem that will take slot-on mounts for accessories such as Garmin computers.

New versions of old favourites

Moving on to bikes you can buy now or very soon, the latest versions of the four-bike Ultra CF race bikes all use the same lightweight carbon fibre frame and fork that Decathlon introduced in 2014, with claimed weights of 850g and 320g in size medium. For those who want a dependable, ride-all-day bike, there are two new disc-braked aluminium-framed bikes, the Ultra 500 AF GF and Ultra 520 AF GF. Meanwhile, long-standing value favourite the Ultra 920 AF has been updated.

Carbon fibre

There are now three Shimano-equipped bikes in the carbon fibre range, starting with the 105-equipped Ultra 900 CF for £1,399 with Mavic Aksium wheels. The £2,299 Ultra 920 CF Ultegra has the new Shimano R8000 Ultegra groupset and Mavic Cosmic Pro Carbon wheels. At the top of the range, the Dura-Ace-equipped Ultra 940 CF comes with Zipp 303 carbon fibre wheels and a startlingly good finishing kit including a Deda carbon fibre handlebar, Vittoria Corsa tyres and a Fizik Antares R3 saddle, all for £3,500. We don’t know of a race bike with a similar level of spec for anywhere near that price.

Perhaps the most surprising addition to the Ultra CF range is the fourth bike, the Ultra 920 CF Potenza which will have a full Campagnolo Potenza groupset and Campagnolo Zonda wheels for £1,999. Potenza is supposed to be Campagnolo’s rival to Shimano Ultegra, but with Ultegra R8000 costing bike makers more than its 6800 predecessor, Potenza now slots nicely into the gap between Ultegra and 105. It works really well too. The Ultra 920 CF Potenza will be in the shops in mid-April.

Decathlon launch – riding 13.jpg

I was able to get out for a ride on an Ultra 920 CF Ultegra, on a loop that comprised 400m of climbing in about 12km, and then a twisty plummet back to the start. The Ultra 920 CF is a nippy climber; a smack on the pedals is rewarded with an eager surge forward. The shifting and braking of the new Ultegra R8000 components is superb, and stopping gets a boost from Decathlon’s use of a direct mount brake up front, giving a very firm feel.

The Ultra 920 CF demands your best game on descents. It loves to be thrown hard into turns, to the point where it’s initially a bit of a handful. I really needed more time to get used to it than a short descent afforded, especially when I was mostly trying not to get in the way of Decathlon’s UK cycling chief Peter Lazarus, and using the rest of my concentration to avoid exploring the slopes that dropped away beyond the road edges. That descent was still lots of fun, with the Ultra 920 CF urging me to go harder out of every bend.

Gran fondo

2018 Decathlon 520 AF GF 1.jpg

There are two new models under the heading of Ultra AF GF — the GF stands for gran fondo, designating these bikes’ intended use of long days out. Both bikes have butted aluminium frames with full carbon forks and front and rear through-axles. The cheaper of the two, the Ultra 500 AF GF has Shimano’s Sora 9-speed groupset with Shimano BR-RS305 disc brakes and Mavic Aksium Disc wheels and costs £899.

Another £400 gets you the Ultra 520 AF GF with SRAM Rival transmission and hydraulic disc brakes, Mavic Ksyrium Disc wheels and a Deda/Fizik finishing kit including a Fizik Antares R3 Endurance saddle.

Slinging a leg over the Ultra 500 AF GF quickly reveals it to have exactly the handling traits you want for long days exploring tiny roads. It’s accurate but steady, leaning smoothly into corners and while it doesn’t leap uphill like the Ultra CF, it makes good progress and needs very little concentration to keep it going where you want it to. This is a lovely bike for enjoying the scenery as it unfolds below you.

Who's that fat bastard?.jpg

As I returned the bike I said "I really like that, but can I have it in carbon?" 

"Give us another year or two," came the reply. See what I mean about not being exactly secretive?

The only obvious deficiency of the Ultra AF GF bikes is their lack of rack and mudguard eyes, an absence that’s down to the European market seeing a bike like this as more of a race bike than a practical machine.

Updated Ultra AFs

2018 Decathlon Ultra 900 AF.jpg

Previous aluminium Ultra AF bikes have come in for criticism for their rear brake placement. With the rear brake tucked under the chainstays, the Ultra AF bikes looked tidy, but tended to suffer from brake rub when you climbed out of the saddle, and the location is fiddly if you have to make brake adjustments.

For 2018, the new Ultegra R8000-equipped Ultra 920AF has the rear brake up on the seatstays. It’ll be available at the end of March for £1,299. The current 105-equipped Ultra 900AF will carry on using the chainstay brake placement until some time around the end of summer 2018.

2018 Decathlon Ultra AF Women 1.jpg

In early October 2018, Decathlon will launch a women’s edition of the Ultra AF with a complete Tiagra groupset. The frame will be the same as the men’s bikes, but with stem, bars and saddle tailored for a woman’s anatomy, including a saddle developed by Decathlon’s own in-house team of female riders. It’ll retail for about £799 in sizes XS, S and M, which Decathlon says will fit women from 150cm to 175cm tall.

Shoes

2018 B'Twin 900 shoes 1.jpg

There are two new road shoe models, both made for Decathlon in Italy.

The new version of Decathlon’s entry-level shoe, the B’Twin 500 (below), is already available for £49.99. Compared to the previous version it gets a fibreglass-reinforced sole instead of one made from straight nylon, and drillings for two-bolt SPD cleats as well as three-bolt Look-style cleats. There will eventually be six colour options, including white, navy blue and red, but at the moment Henry Ford’s famous quip applies: any colour you like as long as it’s black.

2018 B'Twin 500 shoes.jpg

The new 900 model road shoe (top) looks like a lot of footwear for a modest price. It has a ventilated, full carbon fibre sole, twin-dial closure, perforated upper and lots of clever detail, such as quick-drying materials so they won’t stay soggy for long if it rains, and a channel in the heel padding to reduce irritation to the Achilles tendon. Unlike many Italian-made shoes it has a medium-width fit that’s a bit higher and wider in the toebox. They’re expected to be around £120 and to be available in late September.

Clothing

Decathlon’s bike clothing has always been terrific value for money, but, well, let’s just say the styling hasn’t set the world alight. That’s set to change with a range of new garments with tasteful, slightly retro styles for men and some striking patterns for women.

Here's a few examples.

But why postmount brakes and 9mm quick release in 2018/2019? think a future proof bike should go for flatmounts and 12mm axles....ok it's just to discuss, a good bike is still a good bike even with non up to date (trendy or fancy) components, i'm still pedaling my 1990 steel bike, but i would be more pleased with a setup like the Ultra AFGF, in fact that's a 99% perfect bike, it's missing the fender mounts near the axles.

i'm waiting the ultra 500 AFGF to be in the shop to see and maybe buy it, or i'll upgrade to the 520 AFGF, in the shop is already available but not my size yet, this news puts me in pause, the Adept is actually cheaper, with fender and rack mounts that might suit my needs better, at least the mudguards, but cann't wait too much, spring is here right now, any infos on the release date please?

Clearance for 42c tires, 105 and Hy/Rd brakes, tubeless rims for £750?

Going to be seeing a lot of these around I think.

The Adept looks suspiciously like an Sworks SL6.

Is the adept the only bike that has drops, rack mounts, mudguard mounts, wide tyre clearance, _and_ discs?

 

I looked around, and ended up with a GT Grade (possibly on the recommendation of this website) which supposedly had all those but doesn't have rack mounts.

Another potential buyer for the Adept here, looks like a bike that ticks all the boxes. The only "bad" thing I can think of about that bike is that apparently it has QRs instead of thru axles?

Really impressed by the Adept - on the buy-list for next winter. 

I really like the look of the shoes, but Decathlon stop at size 46.

Pleased to see they've finally delivered disc brakes at the current Triban 540 price point, long overdue. Still don't get the lack of rack/guard eyelets on the AF models, does the market really refuse to buy a bike if it has them? Hide them on the inside of the stays if need be...

Interesting comment about chainstay mounted brakes.

My Rose Xeon came with chainstay mounted brakes and Fulcrum 3 wheels, which are apparently relatively stiff wheels. Took no effort at all to make brakes rub, now have to run them really slack and with the lever wound completely out. 

Hadn't realised this was an issue with where the brake was mounted, makes sense I suppose. It's also a horrible location for picking up road spray...

B'Twin / Decathlon absolutely smash it when it comes to value.  I wish they did a CX bike and a TT bike though.  The Ultra 940 looks ridiculously good, although the two colour bar tape is a bit nouveau riche!

I saw a road going disc equipped bike in my local Decathlon store around eighteen months ago and was fully expecting to see a new range but that didn't happen. I thought they had scrapped the idea but apparently not, look like cracking value.

I agree. How hard is it to make a single color paintjob that suits commuter's needs and be sensibly priced?
