 :quest:My chains are stretching prematurely.
Both were Sram PC 48s
  1@ 3000 mi.
 next@1500 mi.
  I have been told that Sram 48 is as durable as more expensive 58 and 68 .
Does anyone know of a longer lasting chain ?

Hello, first I must ask what kind of lube your using and how often.  Ive worked in a motorcycle shop for years and own my on bicycle repair place.  So Ive tried alot of chemicals from both worlds.  I personally believe that Honda has the best chain lube, and remember always spray it from the inside of the rotation to out side for best penetration.  Always helpful to do it on a stand so its easier to clean off the flingings.

How are you chains being measured for wear?  The Park "Chain Checker" and similar tools are notoriously inaccurate and you may be changing the chains much too soon. The only accurate way to measure chain "stretch" is to use an accurate ruler and measure between the center of two pins, 12" (24 pins) apart.  If the measurenment is less than 12-1/16" the chain is fine.
