MRP has progressive springs available now. Unfortunately only in 50lb increments. https://mrpbike.com/products/enduro-progressive-coil-springs

Yeah it's high. Obviously a large investment cost for them.
I am lucky they won't fit in my DHX2 as I'd be tempted to try one.
There's these - http://www.extremeshox.com/product/ext-storia-lok-v3-enduro-racing/
I may wind up trying one on the Bronson at some point.
Wonder if they make any noise on the trail?
Expensive? How much does Fox SLS springs cost in Murica? In Europe they are around 170 € which is about 190 USD. SAR lightweight springs are about the same price as MRPs
I agree that it's not cheap but it's on par with the rest of the market...

Fox Trump-orange lightweight springs are 130.00 US$ at both Jenson and UniversalCycles.
Cane Creek Valt lightweight are 60.00 at Jesnon.
'Bit pricey, but for something as important as a spring, if your frame can take advantage of it, I think it may be worthwhile.
There are things on the bike that you can drop more than a buck fifty on that won't bring as much benefit as an optimized suspension.
It will be interesting to see how these work out in the real world.

I think there was a newer thread where someone was asking about progressive springs but I couldn't find it, sooooo-
Sytace seem to be making them for the Liteville Ballcrusher Moped-

Does anyone know where the progression starts kicking in on various progressive springs? Is it the same across all progressive springs (assuming a typical 20% progression), or are some later than others?
Cane Creek shows a graph that has it starting to ramp roughly at the middle of stroke. I think this would be great for adding pop when you're pumping. https://canecreek.com/product/coil-shock-springs-linear-progressive/
DVO and MRP don't have any graphs.
Sprindex shows it only ramping up at the last 15% or so. Probably nice for bottom out but not much else. https://sprindex.com/pages/overview

Shockcraft on Instagram: "Truth test on the @sprindex_adjustable_coil using our @laba_seven computerised spring tester. Yes the adjuster works and works well. But the adjuster range is smaller than advertised. This 610-690lb/in coil (55mm stroke) graphed out at 590-640lb/in in the 0.5-1.5" stroke range. Scroll across for Bomber CR fitment and spring-rate graphs. Get in touch if you need one. They fit most common shocks with three lengths and 5 rates in each size. #shockcraft #sprindex #suspensionengineering #mtbsuspension #coilspringsuspension #marzocchibombercr #suspensiontuning #suspensiontech #springdyno"

Thanks! I knew there was another brand I was forgetting. I might try one of these, since they make one that starts at 375. I am currently on a 375 EXT, and a 400 is too much, but 350 would be too soft initially.
Edit: fuck, they're DH springs / 75mm stroke.
I have an MRP 350, but it seems to add quite a bit of deep-stroke harshness due to the damping not matching the increased spring rate...
Just general tinkering. More mid-late stroke support to get more pop out of pumps, while allowing me to back off the LSC for small bump. Also, just experimenting to see what a bike with very high progressivity and coil would feel like.
Damn, $230USD to get one here. That is crazy!
