I bought a couple of bottles of Bike Milk back in May of last year and its is by far the best lube I have found to date!
I used it on my daily commuter through rain and shine down here in Melbourne with a little bit reapplied every month or so. Only now after 8 months did I feel the need to clean the chain and reapply it like the first time! I think it works perfectly down here. I also do a lot of riding on the singletrack trails around Melbourne and Bike Milk just suits the conditions perfectly – I have found that wet lubes pick up way too much dust and the dry lubes only last a very short time.
You definitely need to sort out more Victorian outlets so I can stock up from LBS without ordering out of Queensland!
Keep up the good work!
