Spindle Type: 30mm Diameter

  • M30 Cranks

    M30 Cranks

    Product description

    The best way to describe this model is, “It’s a White Industries mountain bike crank”.  Simple.  The M30 is a direct replacement for most mountain cranks from the big “S” companies, but with a lot more options: two crank arm colors, eight extractor cap colors, three 1x chainlines, a 2x chainring option, and seven crank arm lengths.  Like we said, options!  Check out the comprehensive information below for all the details you’ll need to help navigate to the correct set up for your bike.

     

  • A30 Cranks

    A30 Cranks

    Product description

    The A30 is part of our 30mm spindle line of cranks which also includes the M30, R30 and G30 models.  The “A” stands for adventure and the “30” is for the 30mm spindle.  Made here in our shop, the A30 draws on over 30 years of crank manufacturing experience with a focus on all the White Industries hallmarks; functionality, durability, and clean design.  The best way to describe this model is, “kind of odd and probably not going to fit your bike.”  So read all the info below before you purchase….

    The A30 combines our R30 road crank arms with our M30 mountain spindle to give you an odd mix of a mountain chainline with narrower crank arms that will not fit on a mountain bike.  So what bikes will this fit, and why would I need it?  There are some gravel frames out there (mostly custom made) with 73mm wide bottom bracket shells that require a longer spindle than the R30 or G30 crank has, but also have narrower chainstays that don’t need the wider crank arm stance of the M30 crank.   That’s where the A30 comes in.  Think of it as a mountain crank with a slimmer Q factor.  They come in two crank arm colors, eight extractor cap colors, three 1x chainlines, a 2x chainring option, and six crank arm lengths.  Check out the comprehensive information below for all the details you’ll need to help navigate to the correct set up for your bike.

    Product description

    The R30 is part of our 30mm spindle line of cranks which also includes the M30, A30 and G30 models.  The “R” stands for road and the “30” is for the 30mm spindle.  Made here in our shop, the R30 draws on over 30 years of crank manufacturing experience with a focus on all the White Industries hallmarks; functionality, durability, and clean design.  The best way to describe this model is, “It’s a White Industries road bike crank”.  Simple.

    The R30 is a direct replacement for most road and gravel cranks from the big “S” companies, but with a lot more options: two crank arm colors, eight extractor cap colors, three 1x chainlines, a 2x chainring option, and six crank arm lengths.  Like we said, options!  Check out the comprehensive information below for all the details you’ll need to help navigate to the correct set up for your bike.

  • G30 Cranks

    G30 Cranks

    The G30 uses our M30 mountain crank arms mounted to our R30 road spindle so you get road/gravel chainlines but with a bit wider Q factor as well as more room between your crank arms and chainstays.  It is a direct replacement for most road and gravel cranks from the big “S” companies but with a lot more options: two crank arm colors, eight extractor cap colors, three 1x chainlines, a 2x chainring option, and six crank arm lengths.  Like we said, options!  Check out the comprehensive information in the tabs above for all the details you’ll need to help navigate to the correct set up for your bike.
