Hi guys still looking to upgrade rear end of my trek rail 9.8 2020 , I want to stick with rockshox as i like the lyrik and have OCD about mis matching parts , does the rockshox ultimate thru shaft that comes standard with the higher end models have much low speed compression turns on it ? I'm worried that the non trunnion version will hit my frame it's a large thanks

Hi there,
I have a 2020 Rail 9.8 and fitted a Fox DPX2 to replace the crappy ReActiv shock.

I also now have, in my possession, a 2021 Super Deluxe Ultimate RT3 straight off a 2021 Trek Rail 9.8 that my mate has bought. So it's effectively brand new, it's certainly not been ridden!

Therefore it's trunnion and fits perfectly! I tried it on my medium, out of interest, and it fits which you can see in the photos.

I "think" it's got 3 settings for compression - that is + / 0 / - plus the pedal platform option, so is that 6 settings!?!?. You can see them on the dial photo I've attached.

It's for sale now, he's bought an Ohlins coil o_O

£350 posted or if you're around Worcester / Stroud / Cardiff happy to meet.

What about the Fox DPX2,better than stock one? Size was 230x60? What I don’t know,is the tune Trek Rails are running. I was offered a second hand one.
Thanks

If you’re in the UK I sent the DPX2 to J tech suspension and for about £70 (I think) they changed the stroke and tune to match the Rail. Bargain!
It is shit loads better than the crappy Reactiv shock! I’m really pleased hence I didn’t even investigate using the 2021 rockshox shock.
