I’ve had a few rides on mine after moving from an MRP Ribbon Coil. So far so good, they are very supple in the first half of the travel which does make them ramp more than I am used to. I added a fair amount of compression damping after the first ride having started nearly open.
I liked my MRPs but the compression damping was just too high off the top, even though I ran it fully open. This was tried with both light & med springs (which made little difference). They were great on fast rocky sections as they never packed down, but didn’t give the carpet ride like benefits that coils can on other stuff.
Before that I had Marz 350 NCR Ti coils and I’d say the Selva’s are definitely the most supple of the 3. The adjustability on offer is a big bonus, and will mean I am able to set them up in a way neither of the others could be without custom tuning.
