    Lightweight crankset options for 83mm DH bike.

    I want to drop some weight on my M3. I weigh 155-160lb.
    I have an ISIS bb with old FSA v-drive cranks.
    I want a new set of 165mm cranks that fit my 83mm bottom bracket.

    I would love to run XT, but from what I understand they don't come with a long enough spindle to work on my bike. Same goes for hone cranks, and saint ones are too heavy.

    FSA gravity lites are an option.

    What other options do I have?

    Race Face makes the Atlas in 83mm spindle but not sure on arm length options though.

    Not sure if they are the lightest, but I have Gravity Lites, 83mm, 165mm on my Canfield. I got them from Go-Ride and they were priced pretty good w/ an outboard bearing BB. I had regular Gravitys then switched to these. I saved about 3/4 lb. BTW, I weigh about the same as you.

    Right now, its just the FSA Gravity Light Mega EXO's for lightweight 83mm cranks that use external bb's. RF doesn't make 83mm atlas yet.

    If you're looking for something to work with ISIS that is lightweight, there are Middleburn cranks and FSA GL as well.

    I third the Gravity's! They are light and fairly cheap. I had to chose an 83mm crank when it came time to build up my Diablo. I was dead set on the Gravity's, but then the Saint's cam into the picture. The Saint's are more $$$, but I wanted something that I knew wouuld never fail me.,.. "knock on wood"....

    If you are running an internal BB plus a tough crank, the weight might be more then the Saint set up. The Saint's (as we all know) come with the Shimano external BB cups. I think, and I say again I *think*, the Saint's with the external BB cups would be lighter then the Gravity's and in internal BB.

    Hussefelt or Howitzer makes an 83mm internal BB, and it is quite heavy.

    Sorry but that just isn't the case.

    OCT's w/a howitzer bb is lighter than Saints.

    FSA GL ISIS Cranks with the FSA DH 83mm ISIS BB is much much lighter than Saints.
    It is even slightly lighter than the 83 External BB Gravity Light setup.

    I wonder whether ISIS GL arms + FSA DH 83mm ISIS BB or the GL Exo setup is lighter, probably the latter.

    The old ISIS Gravity Light arms and ISIS BB are a few grams lighter if I recall correctly. But the old-style pedal inserts (sometimes creaky) aren't as good as the new ones, and the spider on the ISIS arms is a bit more fragile than the new integrated design. I far prefer the MEXO version. Looks better, too!

    Really? I gather Howitzer BB, by itself, weighs more than 400 grams! Saint and Holzfeller crancks should weigh almost the same, but overall, considering BB, Saints should be lighter..

    This thread is 4 years old. 2008 Saint cranks were heavier than the current design.

    Sorry if I resumed this very old thread, but I'm trying to gather information on lightweight 83 mm cranksets myself, and this thread focused on some crancksets I'm considering.

    I need such a cranckset for a trail/AM frame that has an 83 mm bottom bracket box. Not being a DH/FR bike, I'd rather save some weight.

    From what I read, FSA Gravity Light is the lightest option, but it seems very weak:
    FSA Gravity Light Crankset Crankset Reviews

    Truvativ Holzfeller perhaps is the strongest, but with its Howitzer bottom bracket is quite heavy (overall, 1300 grams?). Probably it would be overkill for my needs?

    What about Shimano Saint? How does it weigh, considering also its integrated bottom bracket. I'd mount two chainrings (22T and 36T) as well as a bash ring.

    Final question. If I choose the Saint, may I use a Shimano XT or SLX front derailleur, or I need to use a Saint front derailleur?

    Thanks for your help!

    There's always this option if you can swing it. Light, and Shimano reliability.

    Let me guess, Ironhorse 6point.? I got some BOR cranks for mine that have held up just fine. BOR's a small German company, don't know how easy those canks are to get overseas.
