|Home-brew or Hot Wax?||JimP|

|I measured a DA-7700 chain with 2,000 miles with 1/32 in elongation in 53 inches!! That would be 1/128 inch in a foot!! This chain was cleaned with naptha in a chain box and hot waxed every 500 miles. Hot wax is more work than home-brew but I have no apparent wear on the DA 9-speed cassette at 10,000 miles. The question: should I continue the hot wax routine or will home-brew be as good?

|I have a co-worker that is a fellow bike commuter. Last week he got out of the saddle to power away from a stoplight and snapped his chain. The results where a broken collarbone and broken/bruised ribs.
I'm not sure how many miles he had on his chain, but I suspect it was pretty high. I do know that he keeps it pretty well oiled (think he uses Phils).
Actually the point of my post is that the cost of a new chain is pretty minor compared to the damage it can cause when it breaks. The more mileage you get on a chain the more your chances of it breaking no matter what lube you use. Replacing a chain every 2k to 3k miles is simple insurance to keep this from happening. Also regular replacement ends the lingering question of "is my high mileage chain causing wear on my cassette/rings?"
Just food for thought...
