You'll need to compress the spring (stock or not) to just get one collar to thread. Both collars just threaded on was enough preload for mine, the Xtrig takes up considerably more room the the two lock rings.

I'll let you know what happens. I've already ordered the Xtrig. It fit's only the 19 & 20's. Maybe I'll get lucky, but I dought it. LOL

Not true Hubert! What actually happened is that the lower spring seat is about 20mm (+/-) taller, meaning that the same 260mm spring rides higher on the shock body. Consequently when you loosen the locking rings you also need to use a spring compressor to remove the spring.

You are splitting hairs, it's still a stupid design. Why didn't they just run the thread for the lock rings a few mm further up the shock body and alleviate the need for spring compressors?

the 2020 appears to have a longer bumper, I'd guess that's why the collar is taller. I did see a vid where they lowered a 2020 and they used the short collar on the 2020, I'd guess that's plan if you want to use an Xtrig again .

What the longer collar does is move the shock spring up on the body, and as a consequence guys can use more of the threads to preload the spring. Before you were running out of threads at a little over 15mm of preload. I would have preferred that they get springs wound that were 265 or 270 mm free length and left the shorter collar … although you may still have had to use a spring compressor in that case.

I don't have a new shock torn down here, but I imagine it would, but then you're in the same situation as you were in 2019 and before … not enough threads left to preload the spring more than 12 or 15mm.

I ordered a new spring, a 6.0 for my weight. Don't know if it is a different length or what, but it was ordered from my dealer for a 2020. That being said, I installed it (I did need to compress the spring, on and off), I installed my Xtrig adjuster and had room left over in the tread department. :?:

Set the sag and have ridden it for about 1.5 hours so far.

Hi!

Three guys together we managed to do the spring change process. No need to buy a spring compressor for rare use. Two guys pressing the spring with "special" levers and the third one removing/reinstalling the collar. Dump design in the sense that there is room for more threads higher up. Also for re-using the old collar on the new shock I don't know but in the older shock I believe it was very rare to run out of threads when preloading the spring. The spring would be way too soft for the rider for that to happen. I changed to one step heavier spring on all my previous Beta 2 strokes and even with the stock spring I had threads left if I needed to preload it more.
