What Has Specialized Created?! | NEW 2023 Double Diamond Frame!

Specialized has launched a brand new Sirrus 6.0 and Sirrus X 5.0. The bike has been designed to sit at the very top of their lifestyle/hybrid range and serve those who just want to enjoy being on two wheels. The bike features a brand-new frame design, which is being referred to as a double diamond shape. This is thanks to the new 'compliance junction' which is claimed to provide an even smoother ride. According to a patent Specialized filed back in February 2023, the compliance junction creates 172% greater vertical deflection and 75% great horizontal deflection when measured at the saddle compared to a conventional frame shape. Let us know, what do you think of the whacky new frame design, would you buy one?

The versatility of the Sirrus has always been underrated. Sold as a "city bike, " it's actually a supremely comfortable and capable mile-muncher. I added fenders, bar ends, trunk and bar bags, top of the line Schwalbe rubber and my decades-old Brooks Pro to the one I bought 4 years ago, and this thing will do a 200-mile day better than just about anything I've ridden, including my fancy tourer. It's quick--rides like a flat-bar road bike. The frame on the new one looks like pure marketing, but the line in general is a perfect all-rounder imho.

Back to the 1890s when all sorts of modifications to the diamond frame were tried to make it more comfortable.

What? 10.8kg for a naked carbon bike at U$ 3000.00? They are kidding us, aren't they?

Whatever gets people riding! Nice to see some design on a bike that looks just as good when you ride it in jeans. This is fast becoming, and needs to be, the age of functional cycling.

Smart to introduce it to their Sirius lineup. If it takes off, my guess is it may cross into their other lineups like Roubaix or Diverge. Time will tell.

You could just get wider tires tho without sacrificing frame stiffness and durability.

[mikevandenberg]

Interesting. Look forward to hearing what happens in longer term use. For now I'm going to stick with my previous generation X 5.0. I ride it everyday and race gravel occasionally as well.

Hats off to Specialized for continuing to produce a number of models (including this one) in size XXL. As a way of introducing some compliancy to the rear of the frame when fat tyres are not necessarilty desirable, I say suspension seatposts are probably the easiest route - but if this works and isn't detrimentral to frame longevity, I approve of the looks.

[bendenisereedy]

The thought of those downward seat tube stresses meeting the forward bending stresses from that almost-beam rear arm are making my mind boggle. There's a reason why 99% of road bikes have a two-triangle design and it's arrogant to think you can improve on basic engineering principles.

The questions any owner would face at a cycling cafe would "why the f##k did you buy that!?" hahahaha

[fhotrod]

Someone should take the old carbon fiber sirrus, and this new one, and put the same tires on it. Then ride back to back to see if there is a noticeable difference in ride comfort. I did see the X in person at my local bike shop and rode it. It is a very striking bike, it looks really cool. I have only owned a 2017 specialized diverge comp carbon, and this bike did feel way smoother. But the tires were more narrow on diverge, and no future shock.

Expect cracks on the new seatpost fork thingy.

i ride rough gravel roads in the usa rockies a lot, but casually. i think this bike is perfectly speced for gravel riding. ive been riding a steel frame with 45 mm tires and a specialized carbon seat post, and the ride is not too bad, its tolerable, except when the road bed has a lot of cobbles. so, if the specialized compliance junction adds more compliance at the seat, while allowing for use of a faster 38 mm or 40 mm tire while maintaining tolerable levels of comfort on rougher gravel roads, that will be great. im sure that given specialized design resources, they can achieve the claimed compliance stiffness balance

£2, 400 hahahahahahahahahahhahahaha wasn't that long ago when you could buy an Caad with full ultegra groupset for less than £2000

[davidcraig]

Just looks like another Gimmick from the bike industry to boost sales more than anything

[georgiaguardian]

This would fit my super fit 145-150 lbs body weight perfectly.

[jeffreykaufmann]

Is going uphill harder with a 1x12 vs a 2x11 ?

[thebudgetcyclist]

Specialized is the only company that can media coverage for a flatbar bike

[ricardonunez]

They don't know what to invent to get the money out of your pocket, any bicycle with the same frame measurements takes you from point A, to Point B, to where they want to go with their cruel and bloody bicycle market

[keacoq]

Where do I mount the front derailleur?
