I have been trying out different lubes for a few years now. A different lube for each bike (4)
I started to use T9 on my MTB and was impressed with ease of application, how smooth the chain moved and chain cleaning was a minimum. Well, 2 years later and I wanted to change transmission. The rear derailleur, chain ring and cassette were covered in a very dense film of T9. Very, very difficult to remove. Several hours and I'm still working on it.
Just wanted to tell my experience if you are considering this product
