I had read the topic about FS cartridge “regulary” service and told the guys at LBS about it but they had no idea and claimed that they didnt find anything about it on their “deep googling” 😑
So i had a few idea what i m dealing with. That said, i asked them what grease they are gonna use for the spring if i need it to be serviced. Well... they told me they ve never opened a single one so far. (İt s been more than 2 years i guess since they started selling Roubaix, Diverge etc)
Guess what next; they dont know the new torque value either. 🏆 and ı m sure the guy who did the replacement didnt use a torque wrench cause he told me that 4nM is not enough in his opinion. 😩
I ve read it here that it is 4 nM and also i emailed spz about it just to be sure. Waiting for answer atm.
Finally i took the bike to my friend who is a decent mech guy , to re assemble the whole thing properly according to the manual (fork+cartridge+preload screws etc) and grease/carbon paste them and of course check the torque values.
Im pretty sure that we did it all good but now there is a micro noise coming from somewhere in the headset when i drop the front of the bike to the ground wich we couldnt locate it.
So my questions :
- How tight the pre load screws (2mm) should be when you make them contact the compression ring ? There is not a torque value for these in the manual.
- İs your plastic cap moves sideward just a bit too ? And how to tighten it ?
- We applied shimano green grease for the spring, the collar bolt/nut/shank and the fork assembly , muc off carbon paste between the FS cartridge and steerer tube. I would like to hear your opinion about these too. Do you think Park poly or slick honey is a must for the spring ?
I will update when i get a reply from spz and if i locate that noise.

I'm a bit late to this and late in changing my collar - but Specialized here in NZ were very quick to reply and confirm the torque as 4Nm. They say it's in addition to the other collar changes to reduce stress fractures. Furthermore I believe, whilst no-one wants to void a warranty, it's very much a user task as if you want to change the stack height you have to go through the whole process (less refitting the wee 2.5mm locator screw on the front, incl 242!) to remove shock, change spacers and reverse.
The torque for the 2 screws isnt't specified as that's your preference as it always used to be regarding your headset when you tightened the 'star nut' or such like...
The lower torque IMO, especially as the pdf says to use carbon gripper paste too, is fine as the moments of force required to shift this interface can only act in a rotational way; so if one crashes the stem/shock unit may slide in azimuth; better this than at the next 'weak point' at the interface between upper and lower shock?
That's my coupl'a cents anyway from down here in NZ!
