My Rail 9.7 as well as my girlfriends and buddy’s Rail 7’s all have 203mm Shimano discs. I have no complaints on the brake setup, work really well.
Trek rail rear shock upgrade ideas please

If you have the Thrushaft then probably similar performance but compared to the standard Deluxe that was on my Rail 7....it was a lot better. I only ran the DPX2 for a month until I swapped to a 21' DHX2
thanks …good to hear. Mine had the standard deluxe select + so I just put in a dpx2 tonight. Looking forward to trying it out

I'm 50/50 on whether to switch to X2 or DHX2. Not really sold on the coil and having to experiment with springs when they are $100+ each.
I just used Fox’s spring calculator and it worked just fine.
should add that theres lots of good information on this thread that helped me install the dpx2 on my 2021 med rail 7. i used the existing DU bushings from the fox but sanded down the lip so they were flush with the eyelets. once i did that it was pretty much a straight swap using the existing stock hardware.

Are those bolt numbers for Trek? I can find the first one but not the second? What stroke length spring did you end up going with and spring rate? I'm 200lbs and trying to figure out what spring to buy for a 2022 dhx2.

That’s no bueno at full compression.
Only Super Deluxe that will work is the trunion mount.
thanks for the feedback, its the aluminum frame model, so its the standard mount, not trunnion
Anyone recommend an upgrades air shock? The stock one is under whelming...

Trek part number W583804
Ohlins TTX will definitely fit, Cane Creek Kitsuma might fit.
I run a 2022 DHX2 Coil on a lrg Rail 7 230x65mm. 2022 Fox X2 fits as well.
Hello, I went for the ohlins ttx, imo worth the extra cost, 60mm stroke and it works a treat. Rail 9.8 large.

Have you already fit the TTX22 on your bike?
I also have a 9.8 and i wonder if i ca use the bottom shock screw or if i have to buy the complete axle from the rail 9.7?
Hello, I don't know, I wanted to have a shock I can just take off with all it's fittings, so I know have the original and all it fittings in a box, and I can just swap shocks over with no faff, not that I've taken the ohlins off since I put it on, it's a great shock imo, no faff, set n ride.
Here's a pic from todays ride.

Thanks for your reply, my TTX22 is arrived at the shop, i will pick it up Monday and will see!!
Muddy time !!!
I have a ttx fitted to a 9.8. It needed totally different mounts top and bottom from the standard shock. Tftuned supplied it all for me, they knew exactly what was needed. They do actually have everything listed on their website.
The bolts are a bit spendy, £27.50 each

This thread has been very helpful informing my suspension upgrades to my Rail (9.7 XL 2021) so I thought I would post a few observations. Recently first upgraded to a Zeb Fork (Ultimate 160mm) followed by Jade X (650 LB DVO coil, 57.5 stroke with -7.5mm clip) and I’m pleased to report the combination is brilliant. Frankly I was a little disappointed in the results with just the Zeb upgrade and the old RS Deluxe. LSC was far improved and steering was more responsive, but it still was a rough ride and I really wasn’t any faster. Add the Jade and the results were undeniable. Long standing Strava times on long rocky downhill sections were destroyed on the very first ride, including one challenging black segment where I mistakenly left the compression setting in the middle as opposed to open. The combination is so buttery smooth and confidence inspiring, and will only get better when I dial-in my settings. If I had it to do over, I probably would have started with just doing the damper replacement to the Yari and saved a few bucks, but I’m starting to appreciate the Zeb now that it is paired with the Jade.

Help please… I’ve ordered a Jade X from my local suspension tuner. They refer me to my LBS to order the mounting hardware. My Rail currently has 897km on it, can’t I just reuse the hardware on the bike? I’ve read the post about Fox hardware working (local Suspension co is a Fox dealer too, I asked them on Friday if they have those part numbers in stock.
Can someone please explain what the issue is with the hardware? I understand the stock shock is Thru Shaft why does that change the bolts? Please and thank you.

Neither the stock shock nor the Jade would work with the thru bolt without adapters (an inner bushing and spacers on each side). Basically the mounting hole in both shocks is bigger than the thru bolt and needs a bushing to size it down. After removing the stock shock you could try to remove the the adapters/mounting hardware from the old shock and put them on the Jade, but this takes some effort and perhaps special tools. I also believe the bushing for each shock may be different and needs to be replaced regardless. I opted for all new fox mounting hardware and posted the part numbers on another thread. They work great and are very easy to install.

10 minutes after I posted this my LBS called back and said they should have everything this week. Perhaps I need a little more faith.

Good luck, hopefully it’s worth the wait. Post your impressions once you‘ve run the Jade through a few rounds. For me it previously felt like my suspension was holding me back, now the weak link is clearly my skill level

More mental planning, the the guy at my LBS told me he only ordered the lower bolts (makes sense because of the thrushaft). Now I'm worried he should have ordered the top mounting hardware too? I don't have the tools to remove the old hardware. I'm quite convinced the suspension shop can sell me the Fox top part if needed but I can probably still add it to my Trek order.
I have the Zeb Select+ and have ordered a 170mm air spring and the Push HC97, spent weeks trying to find the 2.1 charger upgrade but too hard to ship to Canada. It's going to feel like a whole new ride!

Oh, now I understand, you have a newer model than I do with thru shaft on top. The top of my old RS Deluxe was mounted top and bottom with the same style mount as yours is on the bottom. Therefore I needed bushings etc top and bottom. I have a Jade X metric 230, I’m guessing maybe yours unlike mine will be trunnion style mount top. I don’t have any experience with this type of mount but assume your LBS is all over what is needed.
