    Carbon Bars and Grips: Ergon's = no go?

    So I just got some Easton Carbon Havoc's and kinda bummed that my Ergon's won't work because of the offset clamp . . . .

    Now I'm looking at the ODI Rogues . . . can someone confirm for me that the clamp's pinch point isn't offset like the Ergon's are (i.e., closure is on the centerline)?

    Thanks

    I dunno . . . maybe I'm reading the instructions wrong, but go to page 4 on the Easton Havoc Instructions Page and that's my take. Maybe these instructions don't apply to lock-on grips and only bar ends?

    Note: I don't want to use bar ends . . . i just want to use my Ergons (that DON'T have bar ends).

    GA1-Ls on Easton Havoc Carbons and all good. However I wouldn't use the supplied endcaps. Bars are too thick so used the one thinner endcap that comes on the outside of the package for cosmetics and grabed another from another package.

    After two months my left grip is slipping around its housing.

    So I ended up getting a set of ODI Rogues . . . they are loosely on there for right now.

    How tight do I need to torque these down?

    It just to the point where they stop slipping?

    Is it a specific torque value?

    Do I need to use friction paste?

    Generally 4-5 Nm torque. Ritchey torque-key works well and is cheap.

    I almost bought one of those until I realized you can't change bits. Its permanently a 4mm hex which is fine for many (most) things but not everything

    mine spun around a little until i used friction paste
    use it on the shifters and brakes too

    i think the bontrager torque key has swappable bits

    Same thing with the bontrager key . . . its welded in there (my LBS and I have tried to disassemble them).

    I can see why the paste on the shifters/brake levers might be necessary, but I actually want them to spin pretty easy if I get in a crash. We'll see if I can get by without it.

    electrical tape and gel toothpaste

    Hey,
    If you don't have any friction paste .....

    On my Easton carbon bars instead of friction paste I used some gel toothpaste and one piece of electrical tape (as a shim).

    I've got some Ergons on some Bontrager XXX Lite carbon bars, no real problems so far. They do slip a tiny bit, but I'd have to really wrench on them to do it. Haven't done it accidentally yet.

    I do have to get some friction paste anyway, my seatpost clamp (also carbon) keeps slipping slightly, so I may as well apply some to the bars.

    I like this idea!

    Edit: I'm assuming you're talking about the old-timey type vs the gel type

    Correct. For most things that you want that little torque for, 4mm is the bit. If you want to be able to change bits, you will have to go for a torque wrench, which is sadly a whole lot more expensive.

    Right. I'm looking at the shimano pro model. ~$100.

    Just torque it until it's stiff and doesn't move. I've been doing that for years, no slippage, and various sets of monkeylite carbons have held up great.

    This only effects out barend models when NOT using a re-inforcement plug. The non-barend models are OK for use on carbon bar as long as our torque spec does not exceed the torque spec on your carbon bar of choice.

    Harbor Freight. Get on their email list. I got my inch-lbs model for 10 bucks, and just scored the 3/8 drive one for the same. Precise enough for bike work.

    Hmm. Well, I have the ODI's now so I will try them out for a bit. But I have had problems in the past with numb hands so I may switch back to the Ergons. I dont know off hand what the torque spec is for the Havocs. I'm guess 5nm.

    I shoulda done my homework first before running out and spendin' money . . . Easton has also confirmed that off-center clamps are fine for lock-on grips . . . just not bar ends.

    In other words, the Ergon's are fine to use . . .

    So I have been running the ODI's for a few weeks now and I took them off tonight to find that the clamps had left a groove in the carbon. Its not very deep and I doubt its beyond the surface finish, but deep enough that you can catch it with a fingernail.

    It also took a fair bit of torque to get them to not slip. No idea what "value" it was as I didn't use a torque wrench, but I basically would tighten each bolt 1/4 turn until I couldn't move the grips. It took a fair bit to get them "locked" (more than I expected) and now the bar is marked. I don't care about the mark, but its more of a concern that over time this will weaken the bar and lead to failure at that point.

    So my thoughts are:

    a) friction paste
    b) electrical tape under the clamps
    c) back to the Ergon's

    I went with the friction past. Will post an update for future reference if anyone else ever finds themselves in a similar situation, but initial impressions are that this did the trick. Much less torque required to sung them up.
