Also if depends if you run a Lockout and use it. I like v supple but I use a 3 pos for the rear only (front stays open all race). If you ran no lockout you might need to depend on a digressive shock / asq

I donāt follow mtb tech as closely. Is this supposed to replace the 35mm stanchion Ultimate or?
Sounds like itās mostly a normal update. SID is still 35mm and slightly lighter. SID SL is still 32mm and also slightly lighter. They both also have longer stanchions (or lowers?) and are now offered with a 3-pos lockout.

Interesting. Looks like a nice fork.
I actually thought they were working on a 120mm SID SL, Iām glad itās the regular SID for stiffness. I hope they have sorted the bushing issues with the increased overlap.
Having recently picked up a bike with a Lyrik and having had a SID on my old Anthem, I really rate the RS stuff. I was too scared of having a faulty fork to try the SID this time around though on the new build.
The new SID blue on the BikeRumour/Flow review is a heck of a nice colour! Surprised theyād move away from that identifyable sky blue though? I also feel vindicated by Kaz suggesting the wireless remote, I canāt believe they havenāt done it, but I imagine they donāt want to cannabilise the potential FA market.

Iām pretty excited about these. Overall Iām very happy with my SID Ultimate but the bushing issue is a bit annoying (Iāve warrantied one and thereās minor play developed in my current one) and Iād really like to have 3 position remote lockout to match the Fox DPS I have in the rear. Iām a big fan of the climb mode I used to have on the Spark.
I donāt see these available anywhere yet - any one have a line on availability?

Iām in generally agreement with you (more bump absorption = more speed), but Iām curious if you have any way of quantifying the effects or figuring out whatās āoptimalā. At some point you have too little anti-squat and are suffering from pedal bob, or supple becomes unsupportive, etc. I ask because you seem to have put a lot of thought into your set up and are using it a high level.

A 350W FTP also helps smooth the trail out 
.
For what itās worth, Iām going to try the 34 on my bike first. I had a 34 on my Spark (very active suspension) and it was manageable but the trail mode was used a lot.
Now with no lockout at all Iām tempted to go 32 for the reasons discussed above. I am worried about spending too much time in the bottom end of the cassette though.
I have a mate whoās strong like Nueromancer and I was trying to convince him to try a 34 but he hated it. Much prefers the 32 even though heās got Watts for days.
I wish Sram would stop listing blatantly inaccurate weights. I got the weight values from a couple of the reviews vs most of the review info just lists the Sram claimed weight. Looks like the SID SL Ultimate not on the Sram site yet.
Figuring out real weight wouldnāt matter much since can just call it similar to old, but now thereās 2 options for 110mm travel added.
| Length | Weight | Size | Name |
|---|---|---|---|
| 120 | 1600g weighed vs 1480 claimed on sram site | 35 | SID Ultimate |
| 110 | 1510 weighed vs 1352 claimed on sram site | 35 | SID Ultimate |
| 110 | 1369 weighed R2 bike | 32 | SID SL Ultimate |
| 100 | 1326 claimed | 32 | SID SL Ultimate |

Is your 34 a SC or the regular? I have a 2020 performance 34 on my Blur TR and am really wondering if its worth upgrading. I am really threading the line between DC and XC with this bike. My buddy says the SC felt like a noodle underneath him and is adamant its not enough for the racing or riding around here. Heās a big guy at 200 lbs, but I am not far off at 180. I would love to try a Sid or 34 SC and see how it feels!

My Spark had a 34 Performance Elite. The new build is a 34SC Factory.
I havenāt been out on it yet, you can immediately feel a significant amount more āsupportā from the SC though with its smaller negative air/tune.
The reviews I read (and it was a lot) all said the 34SC was impressively stiff, not giving much up at all to the regular 34. It looks noticeably narrower, but I canāt imagine it being much flexier, and the tubes look as substantial as ever. Your mate is a big dude though so might be able to flex more out of it. I wonder if itās front wheel flex also?

The German shop r2-bike publishes confirmed weights for everything they sell.
For example the new Sid Ultimate:

Which cog do you all prefer to have the chainring in line with? Assuming 12-speed 10 to 50something, and standard Boost
Really just not sure what people are worrying about with the 34. Itās a 120mm fork. You set it to 15% sag or something. It tracks the ground. It doesnāt bob under my 75kgish weight. It doesnāt feel Uber plush, but it controls the front end through technical terrain. Itās an xc race bike - you can get more support by adding more air 
.
Tracking the ground and not bobbing is pretty straightforward to dial in with most forks (imo). The challenge is how the fork performs at the limits, with limited traction and under hard breaking, especially in technical terrain. Its one of those things where the difference are at the margins, but they are pretty big differences when you hit them.
Its also a function of the terrain you race in as well. I find in really rough, technical descents you can absolutely bleed time if your setup isnāt dialed. I did an XC race in Whistler in June, in a stacked field the winner was on a Fox 34 140mm with Forekasters, which is kind of a crazy aggressive setup.
I think its one of the coolest things about modern XC, is that the courses are getting so diverse that the perfect setup can vary sssoooo much from race to race.

Interesting thanks.
R2 lists the same weight for 100 and 110mm SID SL Ultimate. It sounds like the default is 110 and that changes to 100 with a change in the air spring length. Different spring seems like it would be different weight but maybe essentially the same.
Might be as simple as shifting a spacer.
Those of you running AXS, whatās your preferred shifter type, and location (pictures if youāre able) please.
I have GX AXS and have put Leap Quickshift on but the shifter position still feels awkward. It might be something I quickly adapt to on the trail, I have been moving it around and trying to get a feel for it in the garage while waiting on bits.
I have Blipshift as well to try but seems like I should save those for race day or summertime use (just for maximising battery life).
Iām wondering if the Pod style is betterā¦
Alright yāall, asking a favorā¦
Iām hoping my math is rightā¦ Iām trying the find the point on my MicroSpline hub where the chain is 52mm from the centerline.
The question marks (end cap to start of freehub) are 13.7mm measured with calipersā¦
So 22 - 13.7 = 8.3.
That is, 52mm from the middle of the hub is 8.3mm inboard of the freehub outer edge.
Does that look right?
In case you want to know the backstory, Iām considering a single speed conversion for my Procaliber and I want to know what width spacers to order to get the cog lined up with the Crankset.
