520 Chain and Sprocket Update - 2/19/2006 5:54:02 PM

Ran the RK chain and Vortex sprockets for 5K miles and here are the results:

stretch per 6 pins versus 530 with same mileage: + .0156"
overall stretch versus 530: +.297"

As you can see from the sprockets the aluminum rear has a small amount of wear. Probably has another 2K to 3K miles left in it. Front steel has minimal wear.

And I didn't baby this thing -- ran it hard from day 1.

Main difference I saw was that with the 530 D.I.D. I only adjusted the chain 2 times in 5K miles. 520 RK required 5 adjustments over the same mileage to keep correct slack.

Inside dial calipers. Measured several areas of 6 pins and averaged them out.
