Starling has apparently had "never-ending demand" to produce a raw version of its Murmur frames since its inception and it can now meet that demand with a limited edition stainless version.
The new Murmur Stainless Limited Edition retains the 140mm rear travel/160mm max front travel of its
regular counterpart but it now has a front triangle constructed from stainless steel to complement the regular chromoly rear triangle.
Stainless steel is a new material for Starling but the strong handiwork remains.
Stainless steel allows the brand to provide customers with a bare metal look with none of the oxidization or corrosion that would come from a similar finish on a regular steel bike. However, the brand also claims there are performance benefits too and that the stainless material takes the "‘magic’ feel of steel to the nth degree". For Starling, this means a more supple and lively ride.
The bike is designed around 29" wheels and offers 2.6" clearance with compatibility for Boost and non-Boost wheelsets. The Stainless edition has a smaller-than-normal geometry table as it is only available in large or extra-large sizes but some key numbers include a 64° head angle, 76.6° seat angle and 485mm reach (size large).
Only 15 of these frames will be made and they are available as a frame-only, frame plus shock, or with various build kits with prices starting at £2,330.

available on the Starling website.
Or maybe it just means that the stainless version is flexy AF and/or less durable.
Thought anyone ?
One important aspect is weldability- toughness in the corase grain part of the heat affected zone...as far asthe stuff is mrcroalloyed (Ti, Nb) to hinder grain growth and the cooling time (t 8/5, time to drop temperature fromm 800 celsius to 500) is not crazy you're good to go. Many steel frames break by fatigue related to corroded spots (strees risers created by corrosion), so that's one advantage for stainless tubing.
953 looks way better albeit marginally heavier.
You can’t lump me into the bracket of people who don’t appreciate a steel bike or a Starling for that matter, I may own a steel frame or two myself after all...
I too love steel bikes.
Same with every industry, car buyers seem some of the worst.
Wow that looks niiiiice!
Shame Small company in arizona = unobtainable in Uk
But the bike looks great!

Though I have to admit I'd like to try a slight more progressive linkage with the coil ext. Maybe a second possible shock position in a next generation?
Send me an email to discuss your shock behaviour, I don't think the leverage ratio is the issue, the EXT just has certain traits.
Wonder is Starling have tested it with spherical bearings?
Thanks... My question related more to torsional loads binding the bushings on the shock and pivots rather than shock damage. Hence the question re spherical bearings.
Also weird is the claim that stiff linkages hurt shocks more... If the linkage is stiff, the loads should follow that stiffness back into the frame, according to the article's statements about stiffness. Since the shock, with it's "mostly good enough" bushings, isn't the stiffest path, it shouldn't be a vector for the loads. Even with a yoke, unless the yoke to shock mount is stiffer than the yoke to frame mount, which would be super weird, the loads should track the stiffest connection, which wouldn't be yoke-to-shock.
As you said, I think the question is more about torsional loads applied to the shock mounts. Ok, so even if the bushings seem to be soft enough to protect the shock, twisting them off axis is going to add some friction to the system, and with all the talk of getting friction out of the shock with bearing mounts and fancy piston coatings and such, it does seem like a weird place to say "eh, good enough"
I'm no welding inspector, I just play one on the internet but it does look like there's a few spots that are borderline out of spec. Here's a commonly referenced colour chart for titanium welding:

When it comes to aesthetics of course the colour can be easily brushed off. In the case of aftermarket auto parts, a lot of people are attracted to the pretty colours of poorly shielded/overheated titanium welds. Fortunately that's usually just found in charge piping and exhaust systems were absolute strength isn't overly important. "heat annodizing" titanium parts with a torch after welding is also a popular way of colouring titanium parts for aesthetics.
I think it looks lovely and they are probably all sold already anyway.
If it's good then I would have expected major bike MFG's to adopt already. I prefer tried and true methods of fabrication.

Generalising like you have done, without having done a proper freebody of the system to understand it, backed up with some empirical evidence is little more than speculation...
But to give you some credit, on first inspection you would assume the design damages shocks, but in practice it just doesn't.
You're the one then...
Lots of people love the look of the bikes, so I'm doing something right for some people.
Bumped into a fella on one at my local park and was instantly jealous!
