White Industries  170 mm A30 MOUNTAIN Crankset with Spindle  - BLACK FINISH (includes 1 pair of crank arms and spindle )

This is a new item from White Industries.  It is a set of R30 crank arms with the 30 mm Mountain spindle. Read below for more details.

Brand new set of White Industries Cranks and Bottom Bracket Bolts. Includes lockring for Chainring installation.  These Cranks are truly a work of art!  This listing does not include any chainring.  These are sold separately, see our eBay Store.

Manufacturer description:

For a long time square taper was king, but in recent years the development of new axle standards have redefined crank and drive train standards. White Industries answers this change by offering the MR30 crankset line.

The A30 is part of the 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. While this may seem like a new model, it’s just the R30 road arms mated to the M30 mountain spindle, and finally it is given a name.  This combo lives in that wide open world occupied by bikes that are neither road nor mountain and can be the perfect solution when more chainring-to-chainstay clearance is needed, without the wider Q factor of the M30 crank.  Check out the table below and compare the specs of all four crank combinations to help decide which model would best suit your needs.

Note: Spindle, crank bolts, extractors, adjusting collar, and chairing lockring included.  Chainrings and bottom bracket sold separately.
