Crank Instructions

Install bottom bracket according to manufactures instructions. As a guideline, a 113mm BB will render a 47.5mm chain line. Install the chain ring onto crank by mating the spline of the arm to ring. Install the lock ring. Use the White Industries lock ring tool or a BB lock ring cup tool (open ended C wrench with hook on top)to secure the lock ring to the crank arm. Grease BB tapers and slide cranks onto spindle. The arms should be installed 180° apart e.g. one arm in the 12:00 position and one in the 6:00 position. Grease bolt threads and washers and install. The crank bolt size should be M8 x 1 Use a torque wrench and tighten bolts down to 30 ft. lbs. At this point the cranks should be secure on the bike. Take the bike for a ride and tighten down the bolts once more to 30 ft. lbs. The cranks are now properly installed. Do not continue to tighten down on the bolts. The tapered style BB will allow one to continue to squeeze the tapered BB farther and farther into the crank arm until the spindle bottoms out. Once the spindle bottoms out the crank is rendered useless.

 

ENO and VBC Cranks and Chainrings

 

Material: 2024 aluminum

Length: 170mm, 175mm, or 180mm ENO

  165mm, 172.5mm, 170mm, 175mm VBC

 

Chainring: The ENO and VBC cranks are designed with a proprietary spline that mates to White Industries chainrings. The ring is dropped onto the spline and a lock ring holds the ring in place. The aluminum chainrings are available in 32t, 34t, 36t, 38t, 42t and 44t. VBC rings are available in outer 52t,50t,48t,46t,44t,42t,40t, and 38t. Inner rings available in sizes 38t,36t,34t,32t,30t,28t,26t, and 24t.

 

Lockring: The lock ring is made out of aluminum and can be tighten down or loosened by using a White Industries lock ring removal tool, or a bottom bracket cup removal tool which can be referred to as double ended lock ring spanner. The wrench must be open ended on one side with a hook on the tip of the open ended wrench.

 

Chainline offset: 47.5mm from the center of the BB shell to the chainring

 

Bottom bracket: The ENO crank is designed with an extremely low Q factor: 160mm ENO; 142mm for VBC. With a 68mm BB shell we recommend a 113mm square tapered bottom bracket, however, some frames have wider chainstays and need a longer BB. By simply taking a few measurements on your frame you can determine a suitable BB spindle length for your frame. First measure from the center of the BB shell back along the chainstay 180mm. At that point, measure across the stays. Your measurement should be from the outside of the stay to the opposing outside stay. If the measurement is 135mm or less, use a 113mm BB. If your measurement is higher than 135mm, then add the difference to the base 113mm to determine you BB length. For instance, if the chainstay measurement is 140mm then the BB length would be 118mm.
