I received my Easton EC90 flat bar and Syntace F99 stem today, I was reading the instructions and neither say the torque specs for the handle bar clamp part. The syntace manual said to go to the handlebar manufacturer and the easton manual said to go to the stem manufacturer.
So does anyone know what torque I should tighten it too? what about the carbon paste that came with the stem, I've never used it before. Should I use it? if so where do I put it?

Oh and they both weighed 108g, kind of disappointing seeing that my bar was 108 when it was claimed 99.:mad:

good choices

i believe its 4nm for an F99, check the bolts after the 1st few rides though to make sure they aren't coming loose - just incase!

carbon paste goes all around the bars in the area behind stems faceplate, perhaps also your steerer tube, you shouldn't need to use much.

It's 6Nm for an F109. It should be the same for an F99. 6Nm might be too high for the handlebar though. 5Nm should be safe.

Thanks guys!
Are those torque's, what the torque should be with carbon paste?

Thanks again,
Colin

I first put 5nm then changed it to4 to err on the side of caution

only ever used carbon paste on seatposts when ness best use your own judgement with that perhaps

if in doubt I always ask someone I trust at my local LBS

Thanks Culturesponge,
I went ahead and put a little carbon paste on there, and then torqued it to 4nm (roughly my not-so-great torque wrench only does inch-pounds so I had to convert it). It seems good for now though.

Thanks,
Colin.

great, no probs

i usually get by okay without a torque wrench (using the just enough method) but a Syntace torque wrench is in the post from Germany to end my bad habits

Colin don't forget to re-check the bolts after a few rides, if they come abit loose you can use blue locite to help keep them tight without over torqueing them

a Ti bolt upgrade should get your stem under 100g most peeps use anti seize with Ti bolts in alloy, some use blue locite

sorry forgot this: with the Syntace 2 faceplate's the technique is to wind up the bolts gently with hand power first, top left bolt, then bottom right, then top right ect so the 2 faceplate's end up more or less parallel to the bars equally spaced top & bottom from the stem - then its safest to go ahead with a torque wrench.

......edit for spelling mistake.........

Yeah, I usually only use the torque wrench on the more important things (handle bars, cranks, seat, etc.)

Is it pretty common for the bolts to come loose after a few rides?

I plan on bolt tuning my whole bike..eventually. need a new seat first, though.(pretty hefty at 267g)

Thanks for that picture and the advice on tightening it. Didn't think about that when I installed it, but it's good to know.

yes, especially when the bike is new its a good idea to go around and check tightness of critical bolts as they can work loose, watch out for stem/bars especially carefully as its the last thing you want to come apart while riding!

with the Syntace's 4 bolt bar clamp its common (for our 3 Syntace stems at least) that one bolt works itself looser than the rest & then can cause the rest to unwind - Ti prep makes that harder with Ti bolts, i use blue locite alot on most bolts - so far so good

there's a good thread here about lightweight carbon saddles, some great info from peeps
