    X2 on carbon bars - no slipping ever.

    X2 on Al bars...slipped once as I left the shop. carbon paste. never slipped again over 8 years of CX.

    +1. A little carbon paste is all it takes.

    There are anecdotes that support just about any point of view, particularly with bike parts. I feel that with the X2, though, the ratio of "never had a problem" : "the damn thing broke on me" skews heavily in the wrong direction. FWIW, my anecdotal contribution is that I've had two break and I'm not that big or strong. I'd find something else.

    Given the number of people who suffer either slippage even with carbon paste or cracks even when following the torque specs I think it is safe to say their tolerance during manufacturing are probably a bit too high which lead to a product that end up being either perfectly working or plain dangerous.

    In other words, russian roulette.

    I replaced the one I had because torqued to spec wasn't enough on the bars I had. It didn't slip much but that loud cracking noise when you hit a bump hard doesn't contribute much to the relaxation I seek when I ride. I prefer a stout 4 bolt system.

    When it comes to stems or handlebars, if i have to ask about it then i look at something else.

    +1. Also, what's odd to me is that I've used a single bolt Cinelli 1A stem for years no no slipping. Still do on my Eroica Ciocc ride.

    Go figure.

    Knock on wood, only stem I've ever had crack was the X2, I've tried them twice and I'll not be on one again.

    As good as Thompson is (was?) in supporting grassroots racing I doubt that warranty ever will be a problem.

    Great way to phrase it (in bold)...

    Yes but...there are certain parts I really don't want to fail. The stem is certainly in the top three of that list. I am sure we all agree that saying "they warrantied it" without front teeth would not be uttered happily.

    I don't like making decisions based on fear, but this thread and the fine people of VS ain't the unnecessary alarmist types ... I'm convinced.

    My bike ain't gonna look right, but I just ordered Fizik kit to finish it off. Actually not mad about the looks. Have already screwed up teeth while cycling, so yeah.

    The X4 stem is fine. Doesn't look that much different.

    Oh, I own several X4s. It's the small differences tho. Plus I've been waiting forever for the matchy new Thomson setback post to come out and nada ...

    the cyrano stuff is going to look tight on my bike.

    My experience with the X2 isn't good. It's a pretty stem, but mine slipped a few times after rolling over bumps/rough hits on the road. Torqued to spec, and used the paste, etc etc. Moved on to an X4 and never looked back. I cringe when I see an X2 on someone's bike now. Using one isn't worth the risk to me.

    this is well put and I certainly am NOT in the camp of ONLY X2 FOR EVERY BIKE

    I just haven't had the issues others report, either on my cx or my road.

    one thing really nice about X2 is the smaller stack...like 36mm versus the 43-45mm of many others
