Cannondale Hollowgrams; manufacturing steps
Would like info on the steps Cannondale (Cannondale's contractor) uses to produce the Hollowgram crank arms. For this thread, not interested in the other components that make up the Hollowgram cranks.
What I know or at least what I "think I know".
- billet alloy milled out to create (2) clam shell halves per arm
- these clam shells are bonded together using some sort of epoxy resin
- arms are black or silver anodized
Of most interest, I would like to know if the (2) halves are bonded and THEN anodized or..........the (2) halves are anodized and then bonded together.
No I'm not launching a crank arm to compete with Cannondale. I'm considering anodizing some black Hollowgrams that have multiple shoe rubs. My searches have turned up numerous cyclists claiming they anodized Hollowgrams with no ill effects on the epoxy resin used by Cannondale. Some claim to have anodized their cranks (3) to (4) years back and they are still going strong.
And yes, I know what Cannondale would say about this type of behavior.
There are industry reps in this Forum. There are retailer / distributor types in this Forum who state they have Cannondale employees' ph. numbers. Give those Cannondale buddies a ring and lets see if we can get the REAL scoop.
