    Hope freehub bodies, steel vs Al weights

    I am posting this in case someone is searching for the weight difference between a steel and Al freehub body for a Hope Pro 2 (non-evo) hub (as I was last week).

    I just got steel one to replace an Al one I have that got buggered up. I weighed them both.

    The steel is 170g heavier. (EDIT: wrong, see below)

    Al: 178g (EDIT: wrong, see below)
    Steel: 348g (EDIT: wrong, see below)

    As I was deciding of whether to buy the Al or steel, I searched at length around the web for the weight difference, and saw in a couple places that the steel was about 70-75g heavier.

    EDIT: Sorry, I am a dumb@$$ who got a masters in a bench science, but still apparently can't use a kitchen scale. As stated below the actual weights are:

    Al: 81g
    Steel: 158g

    77 g difference.

    15mm is a second-best solution to a problem that was already solved.

    Whoa. In a similar boat and I know it's a matter of time before I have to swap my alu freehub for the steel. At least steel will last longer. Whatever the case, I need to drop 3-4 tenths of pound off me more than my bike. Thanks for the info!
    I don't know why,... it's just MUSS easier to pedal than the other ones.

    How on earth is that possible? For both?

    A full shimano Saint rear hub _with_ a steel freehub is approximately 350g.

    Donít know. Guess there is more steel in the hope freehub.

    The core of the steel one looks like an identical design to the aluminum one, so if they designed it to work with Al, it is probably more steel than is really needed.

    It is pretty heavy.

    I dug around and some online retailers list steel body to be ~155g. Which is reasonable.

    But according to this bike radar article the entire rear hub with alloy freehub body is 285 grams. Those weights just seem to be off.

    Accidentally. 155g is approx 0.341lb.

    And according to CRC the alloy freehub is 80 grams. I think your scale is way off.

    142x12 hubs are right at 300 grams with the aluminum freehub body, just over 400 with the steel freehub if I remember right.

    You need a new scale.

    My scale is just fine, thank you!

    My scale is fine!

    My ability to use it, however, is apparently not.

    I switched to lbs without realizing it

    That should be...
    Al: .178 lbs
    Steel: .348 lbs

    or

    Al: 81g
    Steel: 158g

    77 g difference.


    I will edit the OP.

    Sorry, folks..... FAKE NEWS!!

    Most decent scales can be re-calibrated for a smaller cost than replacement. It's not a bad idea to have some weights to verify the scale is right from time to time. A nickel is 5g if no weights are available.

    I know, it was in response to those other posts that called for your scale to be involved in an Office Space field party, it was not specifically directed at you or your scale.

    You know, I was tempted to BS and blame my scale.

    Hope used to make freehubs out of titanium. Sad they no longer do.
