So , I have just built up a new frame to me, Transition Spur. As a stop gap I have shortened a pair of 2021 Pike Ultimate's to 120mm of travel. So other than a slightly lighter chassis what am I missing out on by not fitting a pair of SID ultimate with the 35mm stanchion. Will they be more supportive, etc. Pikes are running 4 tokens and 70 ish psi for reference and I weigh 72kg.
Not sure if it's sorted yet but there seems to have been a lot of bushing issues with SID forks.
The other advantage of the Pike is that it can do 130mm which a lot of people like on the Spur. 130mm is also the shortest option on a smashpot. It might sound mad, but I'd love a Spur and then convert it to coil both ends.
Are you going Spur light, or Spur burley?
Had a similar thought as I'm running Yari forks at 120mm. the SIDS are 500g or so lighter but less robust / dont track as well, if that is a consideration. As also highlighted, there have been a few issues with bushes, and I've been told that the bushes ARE NOT REPLACEABLE. SO sloppy bushes with no warranty=new lowers. Genius huh.
Not sure if it's all models, but I think some of the SIDs have pared down dampers (fewer adjusters?) to save weight.
pikes by a mile. seena lot of complaints about the SIDs especially from the bushings.
I've just fitted some of the 35mm SID Ultimates to my Solaris Max, replacing a set of Pike Select forks.
There's the obvious weight difference with the SIDS but in all honesty, I've not noticed much difference in the forks when I'm riding. This could be because I've not had a lot of rides on the SIDs yet due to the poor weather. I guess a lot of it is down to the kind of riding you're doing, mine is mainly XC type stuff.
I've not had much of a play with the pressures on the SIDs either, just sticking with whatever the Rock Show app suggested. I'll try and get hold of a Shockwiz when the weather improves and get them set up properly.
My SID ultimate's are superb. Checked for correct fluid levels from new, and adjusted as typical Rock Shox low.

I'm glad you mentioned that, I've not checked mine yet. Might have to strip them and have a look next week.
Honestly the QC at Rockshox is just terrible. Imagine sending out new forks where the lubrication required for operation are not at spec. Good forks in the main, let down by poor process and QC.
Worth doing I was told by a suspension workshop that a lot of the perceived bushing issue's were in fact noise from lack of fluid.
Mine are fitted to an Epic Evo , looked at other options like the latest Fox 34 step cast, but the SID's are too good.
I run a Pike ultimate on my Spur (with a Deluxe Ultimate rear shock).
Mostly because the SID fork never felt great, got the inevitable bushing slop & were fairly fleecy compared to the Pike. The SIDLuxe shock has been repaired under warranty so many times, I want to set fire to it.
The bike is better for the better suspension.

Some where between the two to be honest. XC / trail duties with gravity lead trails thrown in.
130mm seems an interesting option. I thought Transition did not recommend lengthening the front travel.
Have a look at the 201 page thread on mtbr. It's a pretty popular option.
I just had a look on MTBR the chat I looked at had no mention of 130mm out front so can you post a link , please.
Initially some talk about 130mm being a no go, then someone actually asked transition.
IIRC the Pike offset will be different to the SID and what's recommended for the frame, I doubt if you'll notice though.
I have a 29er SID Select+ and previously had a 27.5" Pike. The SID is light and there is www chatter of bushing issues, but to get the weight down, depending on the model you'll have: no compression adjustment & may need a hex to adjust the rebound. SID give you the option of a bar mounted lockout if that's your thing. I miss my Pikes LSC and RCT3. That said I'm happy with my 110mm SID on my Vitus Rapide FS.
Lots of people running 120mm-130mm Pikes / Deluxe rear shock on the Spur. Seems a better option if you're more on the 'Trail' side of the XC / Trail spectrum.
Officially Transition say 130mm forks are unsupported but unoficially you can run one. There's people running 140mm forks but they've bought the wrong bike IMOH.
As has been mentioned above, the Sidluxe is a bit fragile for aggro trail riding. Smooth flow trails only unless you want to be constantly sending it back to Rock Shox.

Definitely worth searching through this thread as there's everything you'll ever need to know about the Spur in there.

I though my SID Select+ had bushing play from new but did a lower leg service and it instantly went away. Hardly any oil or grease in it from new.
Been completely fine ever since (doing the 50 hour services on time).
If I had 120mm Spur frame would like to try the Manitou R7 as love my Mezzer fork or the new Ohlins RXF34s
Thanks for all the above responses.
I'll stick with the Pikes at 120mm for now and maybe experiment with 130mm in spring. Regards the SIDluxe , I'll see how that performs again when the season changes to enable me to make the right call.
