In this, episode 89 of PowerTec 10, DV corrects some misleading rod lightening tech and goes on to cover the latest in the crank lightening process. At the end of the video you will see a crank down to 53.8 lbs from 55. This is achieved with only about 3/4 of the work done on only one crank pin and counterbalance end. Looks like the target 6 lb reduction is on the cards.
