"Designed for Replaces the highly acclaimed Alur 700. Upgraded with Shimano's 11s 105 groupset & R500 crankset and 25mm tyres. This unique triple butted UCI approved racing frame with a lifetime warranty remains at it's heart with full internal cable routing, ESR ready, powerful direct mount brakes and carbon forks really sets this bike apart. "

Our new B'TWIN ULTRA frame is derived from the Evo Vario concept. Aluminium is an ideal choice for obtaining an excellent propulsion-to-comfort ratio. The variable thickness tubes considerably reduce the weight and ensure excellent performance on all surfaces, even very rough terrain. The design is aerodynamic, the cabling is integrated into the frame and the rear brake is positioned under the chainstays.
This frame is UCI-approved.
Weight: 1400 g in size M.
FORK/SUSPENSION
Our new B'Twin Ultra Evo Vario fork is used exclusively on the B'Twin Ultra Evo Vario frame.The combination of carbon and aluminium is the ideal choice for perfect synergy between the B'Twin Ultra Evo Vario frame and fork.We have achieved a damping effect on very uneven and bumpy terrain such as paving and cobblestones. Aerodynamic design with brake located as close as possible to the fork.
Weight: 550 g in size L.
DRIVETRAIN
Shimano 105 11-speed drive train.Shimano 105 SS double front derailleur.
Shimano 11-speed rear derailleur.

11/12/13/14/15/17/19/21/23/25/28.
BRAKES
Shimano 105 direct mount brakes (fork and chainstay): their double pivot technology offers precision and power. Centring is always perfect with DPB technology, and they are made from cast aluminium and covered with a powder coating that withstands frequent washing.
HANDLEBAR / STEM / STEERING
Compact B'Twin 6061-T6 aluminium handlebar is scaled to the bike size. The compact shape is becoming increasingly common in the peleton, as it allows you to keep your hands low on the handlebars without compromising comfort. The handlebar weighs 320 g in size 420 mm. The stem is also made out of 6061-T6 aluminium. Scaled to the size of the bike. Weighs 140 g in size 110 mm. The steering uses long-life, sealed bearings, with a 1⅛" diameter at the top and 1¼" at the bottom.
WHEELS
The wheels were developed by B'TWIN's engineering office. This pair of wheels is designed for all-terrain use, with 20 spokes at the front and 24 at the rear. The rim is 28 mm high. Very versatile profile and hubs fitted with long-life cartridge bearings.
Weight: 1.790 kg per pair.
This wheel is used by the B'TWIN U19 RACING team in training and competition.

How Ultra is it?

Ultra AF mate.

Fairly well specced bike apart from the absurd decision to place the rear brake where they do. I see no reason whatsoever to spec a bike like that?

Aerodynamics, as simple as that. Plenty of top makes do it too on their aero bikes

Frame is stiffer down there as well so increases brake power. I have the ALUR 700 it's a cracking bike
#5
Again only available in 'XS' which seems common for Decathlon discounted bikes. Is it normal for carbon forks to be only guaranteed 2 years but the main aluminium frame guaranteed for a lifetime? It really doesn't inspire confidence in carbon forks. Would this be a good donor bike to use with a aliexpress chinese carbon frame? If so what sort of price would you get for the aluminium frame? Components seem generally pretty good and light.
#6
Frame got to be worth £100-£150 at least
#7
"Propulsion to weight"

Marketing at its best lol.

This is the simple reason I don't bother posting on here. Too many "experts".....

Would be good to see even ONE example of a professional time trial or pro bike that places their brakes there....

The most I can see a full carbon BTwin selling for in the last month on ebay is £310 here 310 full carbon

By all means buy this half specced and weird framed bike for £600

HAHA!

I did buy it when they had XL, 105 set not mentioned so well worth the money. Great first dip into real road bikes for me, shame a car driver decided to kill it when they didn't see it or me on it. Would buy again if they had my size, and once I can ride again.

OK so because i knew something you didn't that means I'm a cocksure expert or just stating the facts that i happen to know? People like you deserve no advice then don't you and the opportunity to spend your money unwisely at times through lack of information.

Theres ONE example you wanted:
