Anyone using one? [url= http://www.superalloyracing.com/products/ ]SAR Springs[/url]
Looking to shed some weight on my Vivid Coil and these look like an interesting option..
Im not a metalurgist but i think that aluminium alloys have a different fatigue life to steel and Ti. This may not be significant if you are a sponsored rider and get a new item every race day but may be significant if you exceed its working life and have to replace them yourself.
I hope someone who knows a little more about this will be along to help you shortly!
Leaves me wanting to know what it's a super alloy of. It's all a bit vague really, I want to see :"Here is a Fox steel spring of hte same dimensions, this one is X lighter" sort of thing.
IME "Super alloys" is a term applied to certain nickel alloys, usually used in high temperature applications (such as Inconel, used in jet turbines, F1 exhausts, etc).
Although given what it costs, and the fact that it's a pig to work with (and not especially light), I doubt they're making springs out of it.

Alloy doesn't just relate to aluminium. Most metals are an alloy of some sort as the raw metals are too soft, too brittle etc.
Steel is an alloy, so is brass.
Looks like the guy behinds it is the Giant head mechanic. Bruni won the worlds using one too..

450lb spring is 407g, my steel one is just under 700g. Trying to find a Ti weight
407 is around 0.6 of 700, so the 'super alloy' is probably grade 5 titanium which is brill, but it's hardly 'super' 😆
The description seems to avoid saying what its actually made of. That makes me suspicious to start with.
Weights are compared to the equivalent Ti spring, suggesting its not made from Ti.
Total stab in the dark but maybe they are made from Alloy 3J21.
I'm guessing the SAR website is so new that they have not even finished populating it yet. There are two reviews. One is Lorem ipsum, the other is by Dan Wiggins the website creator.
It would provide a lot of reassurance if they described what they are selling on their website: as in what it is made out of how it works, what the warranty is etc. I guess it can't be that bad if winners are using it.
I'm assuming the same material as the SLS and HyperCo springs are made from, a high grade steel alloy.
Assumption is not a good engineering protocol.
Are they made of actual Ally McCoist?
Assumption is not a good engineering protocol.
Not always; for example: It is good engineering protocol to assume that assumptions have been made unless proved otherwise.
A lot of WC DH and EWS riders are using them and the company is owned/run by Dave Garland / Stendec.
Good luck trying to buy one, I have tried a few times to get information and nothing received back!!
Stendec are also importing / supplying EXT shocks - so if the springs they're selling are the same as the ones on the EXT shocks then it makes sense. Be good if this became commercially viable but my experience of Stendec isnt great.
Joe at Starling tried to source me an EXT shock (after DG had promised to be able to supply them) and was continually let down. The shock & spring I had a loan of were great, and really light in comparison to what I have now, but i had reservations about servicing and general customer service
No disrespect to them - they have to build their brand how they see fit but it makes it difficult to recommend if there's no interaction with the end user
I've emailed them but no response yet. I think they may be at the EWS in Whistler though..
I've got an SAR coil on my bike. Supplied by Stendec via Bad Ass Bikes in Bristol. I'd recommend them very much. Noticably lighter than steel, look really good, but most importantly, the feel is very different. Much smoother through the travel range than steel. I never noticed that the standard steel wasn't smooth until I tried the SAR. Worth the upgrade I reckon, about a hundred quid from memory. Fitted to a CCDB on a mid-travel VPP bike for reference.
Aren't thse the equivalent of the orange Fox springs? Those are steel of some sort

Was that the ONLY change? Same weight of spring, same damping settings on the shock etc?
I've been in touch with them and have been recommended a 475lb spring. Currently running a 450lb RS steel which feels OK and runs the correct sag. TF calculator says 411lb..
Apparently they've run tests to check fatigue and after a season of EWS the spring was, pretty much, exactly the same as when new.
Would save best part of 250g compared to the steel spring.
Looks like Marcelo Gutierrez won the Garbanzo DH on using one:
