Hello all,
I have had a few good days out now on my new D30
I wonder if anyone here could help me with a couple of questions?
A few days ago I noticed a little play in the headset...nothing too drastic.....so, (as I have done many times on other bikes) I duly loosened the stem bolts and snugged down the top-cap to remove the play. All well and good now.
BUT.....after I retightened the two stem-steerer bolts I noticed there were no 'Nm' torque settings marked anywhere on my 'Orbea'branded stem.
I'm afraid I have always tightened these sort of 'slip-critical' joints by 'feel' on my other (non carbon equipped) bikes. Poor practice I know! Nipping up tight with just 'wrist action' on a Y shaped multitool. Now I am panicking since It crossed my mind that I did not know whether the forks have an alloy steerer tube or 100% carbon steerer (in which case my 'nip-it-tight-until-it's-right' protocol may prove lack-a-daisically inadequate). I wouldn't want to over (or UNDER) do it!
I've read a few horror stories involving cracked tubes/or catatastrophic slippage
Does anyone know off-hand what the steerer tube is made of before I faff about redoing it all to find out?? Any advice re; specific torque settings?
I am sending away for a small torque wrench this weekend but I hope I haven't gone and overdone it already! But I am still unsure what torque setting I should use. Perhaps I am overthinking as usual?
I've never fettled anything involving carbon components before,
Many Thanks

Hi Widge.
Don't be overly concerned about manufacturers not putting their torque settings on the parts. Mostly it is to protect the stem in this instance. Remember there are two components being affected. The handlebar and the stem. If both have an nm marking and they are different, then go the lesser of the two. In the event of no markings, the standard used in workshops is 5nm. This should be more than enough to hold any bar onto a steerer or handlebar. Just always make sure that all the bolts are done to the same torque and do a visual inspection of how close each bolt has pinched the stem together. There should be equal spacing for each bolt.
Good luck
