2.0 ADJUSTMENTS BEFORE RIDING
2.1 CRANK ADJUSTMENT:
On Lightning Bicycles, the cranks are moved to accommodate
differences in leg length. Adjust the cranks as follows:
NOTE:
Do not apply any grease to the bottom bracket extension
tube, otherwise it might rotate under pedaling pressure.
A) Loosen the two Allen head bolts under the crank tube with a
5 mm Allen wrench.
B) Slide the cranks in or out until your legs are slightly bent at their
furthest extension. (See Fig. 2-1). It's better to have the cranks
too close when making the initial adjustment than too far away.
C) Verify the crankarms/chainrings are vertical using the
alignment lines, then tighten the two Allen head bolts to
30-40 inch pounds.
