Great deal on a bike with hydraulic disc brakes and decent wheels with thru axles / components (deda / fizik). Sram rival groupset. Difficult to find hydraulic discs in this price range.
Not all sizes available to order online (only S and M) Only S now available online but still some stock left in stores.

---
From official website:

Designed for frequent training, endurance cycling and sportives, this disc brake road bike will tackle steep inclines just as well as flat paths, and is a great pick for longer distances thanks to the lightweight full carbon forks, SRAM rival hydraulic disc brakes and comfortable saddle. Rated 8/10 by Cycling Weekly (Jan 2018): "As expected from Decathlon you get great value from the Ultra 520 AF GF. It’s hard to find a place on this bike where money has been saved"










Rated 4.5/5 by Cycling Plus (April 2018): "An excellent mix of sure-footed control, comfort and performance at a killer price"
  • Front and rear 12mm through axles
  • MAVIC Ksyrium disc wheels and fizik/deda finishing kit
  • UCI-approved butted alloy frame with lifetime warranty

RRP is £1299
Decathlon bikes are already good value at RRP, any reduction makes them a bargain.
Looks like a lot of bike for the money to me!
Good price for a bike with hydraulic brakes.
Nice bike period.
"UCI-approved butted alloy frame"
LOL

UCI approved means you can race this frame which means it’s designed and made to a high standard.

It only states that it meets the UCI qualify requirements (principally proportions: 3:1 ratio etc), and not an indication of quality afaik. But I would assume the manufacturers who feel compelled to stump up $15k for UCI certification for each frame would hope this shiny sticker gave their marketing a boost.

However I'm sure that Pro or Semi Pro racers will be eagerly looking at the UCI approved "Ultra 520 AF GF" from Btwin for their next continental race The presence of this sticker on this particular frame is mutually exclusive to the riders who would need to consider this certification.

Sadly this another example of more governing body money making tosh! I do hope this doesn't hit clothing anytime soon (sock length anyone?)

If you look at the Bike Europe trade site Decathlon have had more frame recalls than any other bike manufacturer and I believe they have the lowest weight limits for the rider of any major bike brand with a total load 100kg including bike weight, all accessories, luggage and rider weight, some competitors go as high as 160kg total load. Also this is a 6061 framed bike which is a very common and cheap aluminium so Decathlon achieve low frame weights by reducing strength where as many manufacturers at this price point use more advanced aluminiums which achieve greater strength for a similar weight based on 6066, 6069 or 6011 aluminium. Giant achieve far superior strength and lighter frames with their industry leading 6011 frames. Even walmart's $99 road bike was 6061 based although I doubt the frame had any butted tubes, it has a far higher weight limit than b'twin bikes though.

B'twin road bikes can be fantastic as a package of components and overall spec for their price point but they are best bought by people below average weight for sure and the frames are nothing special. They appear to be Chinese market spec frames hence the low weight limits because bicycles sold in the Chinese market have similar low weight limits maybe this allows b'twin to have a price advantage to their competitors. My point is all evidence indicates these are probably the lowest grade frames of all major manufacturers. The one thing I do like about b'twin is they say it as it is a 6061 frame as many of the US brands and some European brands make up false marketing names for their aluminium and won't even mention what aluminium it really is in the detail but it is normally 6061 even when Giant would be offering 6011 at the same price point.

*Should* be, it's widely ignored and is probably rarely (or never) enforced.

As mine 9 years ago (triban 500se) came with a lifetime frame guarantee, I'm hoping it will break soon so I can get a new bike out of it
