    Light Stem for Rigid Singlespeed: strong enough?

    Recently bought a SS with Rigid On One carbon fork and it came with a very light Loaded Xlite stem in 7075 Aluminium with a carbon wrapped 7075 faceplate.

    The stem weighs around 109g. I feel a bit uneasy riding in the mountains with a very light stem pushing a heavy gear with a 700mm bar and really putting some levarage into the bars.

    Should I be concerned and get a stronger stem like a Ritchey Trail at 140g with a large faceplate or a thomson X4, or am I being concerned about something which should be fine?

    I don't know that you *should* be concerned, but if you are concerned I'd get a beefier stem. An ounce and a half of weight savings is not worth feeling less confident in your ride.
    Yeah I only carry cans cause I'm a weight weenie.

    I know I've used Thomson X-2's on mountain bikes before, but when I used it on the rigid ss I could definitely feel some flex and so I use an X-4 on the rigid single.

    The stem you have might be just fine for your use.

    However, if it doesn't feel right, it's better to switch to a beefier one.

    I've been using a Thompson x2 on my hardtail for years. Only time it broke is when I fell off and also broke 3 ribs. It was just the face plate. Replaced that and still going strong. It probably depends on your weight and style more than anything.

    In your experience, do carbon stems give a little more dampening to trail chatter? What carbon stems would you recommend?

    Old thread, but my thought is, regardless of whether the stem is strong enough or not, if you don't trust it, having that thought in the back of your mind may affect your ride. Change it out, clear your mind and have fun on the ride.
