    Spiderless chainring weight savings?

    I have an AC LoProXT crankset that can run XTR-style spiderless rings. It seems like I'd save some weight if I ran a spiderless ring vs. a spider/bolts/ring setup. Anyone know what the weight difference would be? Any example tooth count would be great... Also, any options for spiderless rings besides Spot and Boone?

    Edit: found some sample weights on Weight Weenies...

    Jericho Suffering - 66g

    58/94mm spider - 74g
    32t ring - 40g
    Short c.r. bolts - 10g
    Total - 124g

    So, the difference would be about 58g.

    Thanks,
    baker

    Hmm...not sure how to take that. Anyways, looks like you run a Suffering. Do you like it? Any particular reason why you chose the spiderless ring over a "normal" setup?

    Thanks,

    If you're looking to lose weight check out profile bmx cranks, those things weigh nothing.

    You are kidding, right? I have profile cranks and another set of similar 3 pc bmx cranks. They are stiff and durable but NOT light. Here is a breakdown for a 3 pc crankset that I happen to have sitting on my desk:

    Cranks arms 19.9oz
    BB Spindle 10.1oz
    BB Bolts 1.4oz
    BB Cups 3.1oz
    BB Spacer 1.2oz
    Spacers 0.4oz
    CR bolt 0.5oz
    32t chainwheel 3.5oz

    Quite heavy (~40). Even if you go with the ti spindle, which saves about 4-5 oz, the weight is way beyond most off the shelf ss crank/bb setups.

    You're a funny guy. But I'm stoned, so what do I know?

    Here is a spiderless set up with profiles...



    Light? Hades no. Indestructable. Almost.

    If you are sweating 50 grams just skip a dang meal and take a dump. You'll lose more weight and probably feel better too.

    My initial response runs along the same lines as appleSSeed. Then again I'm no weight-weenie, I'm more practical about lossing weight.

    There's "Save some weight" ( forum where weight weenies will help you, most I think would sacrifice a significant amount of strenght and pay loads more to save even more weight.

    Apples and Oranges

    A spiderless setup campares to a Florida orange.

    Conversely a spider, bolts, ring setup is like a golden delicious apple.

    Some people like apples but not oranges, and others are opposite. I like them both! Once you turn them into juice I think they weigh the same.
