TimW Posted October 25, 2020 Report Share Posted October 25, 2020 I am thinking about making a spring system for my Deeluxe boots. My idea is to make it very compact with the forward and backward spring parallel to eachother instead of on the same axis. (so far I have always ridden them in walk mode, OK with that, but bit of experimenting never hurts) Does anybody have a number on the spring stiffnesses are commonly used for these systems? Load at max compression or stiffness in N/mm, or lbs/inch (or whatever is used in imperical units), all would be helpful. Quote Link to comment Share on other sites More sharing options...
Mr.E Posted October 28, 2020 Report Share Posted October 28, 2020 If you don't isolate the for and aft springs and you run them next to each other, they are going to act aganst each other. So that pretty well takes away common spring weights Quote Link to comment Share on other sites More sharing options...
scottishsurfer Posted October 29, 2020 Report Share Posted October 29, 2020 its probably possible to design to L shaped brackets which mount to the boot cuff and lower that where each bracket will only compress the one spring but also hold in place the spring it does not compress in place. I know i probably dont make the most amount of sense but i will mock something up in 3d software tomorrow after work to give you a rough example of what i mean.

RideGuy Posted November 2, 2020 Report Share Posted November 2, 2020 For the BTS system these are equivalent to the soft yellow springs springs. There is a list somewhere on this forum that shows the spring rates for all of them.

pokkis Posted November 2, 2020 Report Share Posted November 2, 2020 N/mm figures below are wrong but lbs/in are correct Quote Long (toe side) springs = 3" (7.62cm) long Short (heel side) springs = 1.5" (3.9cm) long Spring Rates: units = lbs/in (N/mm) Yellow "Long" Spring = 96 (25) Yellow "Short" Spring = 200 (56) Blue "Long" Spring = 144 (60) Blue "Short" Spring = 320 (129) Red "Long" Spring = 340 (82) Red "Short" Spring = 656 (177) 1 Quote Link to comment Share on other sites More sharing options...
