Rockshox Sid 120mm to buy or not?

[Me rida my bicycle]

I like the look of the RS Sid 120mm and I am considering getting one. Just something bothering me there's a lot of them for sale like new or used. 

Are they just 💩 or why do so many people change them? 

I have a Fox sc 120mm and just lus to change something but don't want to spend so much money and be disappointed then I'd rather just change the decals on my fork. 

Looking forward to hearing your opinion. 

Thanks

If your bike can take it, Id just get a Pike ultimate in 130mm unless you are concerned by the slight increase in weight. Its a far superior and way more versatile all round trail fork imo. If you do a spread of different riding that is. Those xc forks are all noodles because they prioritise weight over stiffness. Its very noticeable.  Especially if you aren't a featherweight. Pike has a better damper too with all the dails and knobs to get you confused on fork settings lol. Do you use or need lockout?  

Even consider the fox 34 (non sc). Performance Elite gets you all the factory goodness without the overrated, flakey Kashima. I think the 34 can do 120mm. A Performance version will basically get you what the Sid offers in terms of adjustability. 

i think for you to feel a noticeable difference you’d have to jump to a stiffer chassis. Maybe the Sid will offer a slight increase in stiffness over the 32…but it still wont be that stiff. More stiff = holding lines beter through rough sections, corners etc, also more direct feel. 

2c: consider the riding you do first and foremost i’d say. Ive met you on the od occasion and you aren't a 60kg racing snake. You might extract noticeable benefits from something a bit stiffer bolted to the front of your bike.

Ps: if you ask me you see them on sale because they are mostly specced on marathon / modern XC bikes…maybe the od downcountry bike. XC guys have this thing in their head that more travel on modern bikes = worse. They basically just want rigid forks with some squish, so i think they either get something lighter or with less travel.I don't know, hard to say. Maybe someone with experience can chime in. 
 

I do know though that you would rather want a Pike on something like a SC tallboy and there are plenty of dentists around…
I have a Pike ultimate (140mm), it adorns my banshee hardtail or my wife’s hyrax depending on my mood. Its such a good fork for what it is. It ls obviously not as stiff as the 36 and 38mm monsters we use on enduro bikes but it doesn't mind to go as hard .

What Morne said!

I have a Sid 120 on my 2022 Trek Top Fuel and it's not bad for an XC fork. But you feel the need for a stiffer/better fork when things get chunky and rough. I'm not a 60kg racing snake (68kgs) but am seriously considering a 130mm Pike. Willing to take the weight penalty.

Are you talking about the 35mm SID? I had one for a while on my Top Fuel. Honestly performed way better than I expected it to (72kg odd rider on a variety of trails). I tried the stock damper and the Raceday damper and was equally impressed with both of them. I eventually swapped the SID for a Pike as I wanted to go 130mm up front on the Top Fuel. If I had to choose between a Fox 34 with a Fit 4 damper and the SID, I'd go SID every day of the week. It is just plusher and more comfortable to ride. Fox34 with a Grip 2 vs the SID would be a tougher choice. Just be aware that the first gen of these updated SID forks have well documented issues with loose bushings.

I think in just two posts you have a picture of why there are a few SIDs floating around…and i guess its the opposite to what i might have thought initially. People obviously swopping or looking to swop 120mm SIDs for 130mm Pikes😉

130mm Pike any day...the SID just felt harsh and rigid no matter what settings I tried on my Epic Evo..

Sid 120mm is a 35mm stanchion chassis.

Its a race fork, Firm compression tune for pedalling efficiency and the LSC dial does very little. It needs a air spring tune. Remove a volume spacer from both (+) and (-) ends of the air spring. It will run a bi mt more sag but be much more supple. For some reason factory tune is firm for the shop floor because that's what buyers want to feel in a fork to be used for "Epic"

Thanks guys, think I'll just stick to my 34sc because at 120mm I'm already pushing the Limits of my frame. I have no issues with the ride I just like the shiny decals on the Sid 😂 the silver Pike ultimate would look sweet on my bike. Weight is not something I'm to bothered about no use have a light bike and I'm 100+ 😁

the SID in my Epic Evo already had no volume spacers...

Yet stil as stiff as a 2-week old banana when you ride over anything bigger than a pebble or weigh more than 80kg. Those things have more flex in them than a politician’s moral compass😅

That was with a SiD Select +?

you sure there’s nothing wrong with it line tight bushings or something blocking the compression valving?

[guidodg]

yup , nothing wrong with it and it was serviced by Stoke… no comparison to a Pike😉

Of course no comparison for only 200 gram penalty. Totally different tunes. If plush is what you want on the descents then Pike. If a pedal platform is what you want for honking up hills at threshold then SiD and live with the less than plush feel on the downs. Horses for courses

Yep. This is the dilemma for a do-it-all bike owner. I've done long marathon rides (Attakwas, K2C) and love the SID for this stuff, but I also enjoy Donkey Trail, Cobra and chunkier terrain. SID does get a bit overwhelmed in this stuff.

Even with my Ocho I have to use the LSC during a ride besides the lock out. 6positions on offer that goes from magic carpet plush to won’t budge when honking stuff but still plush enough for the bigger hits. You will lose small bump compliance unless you run more sag and subsequently more negative chamber volume.

i think the Öhlins XC fork is also good in this regard but a bit of a challenge to get set up well
