I ordered some bits and bobs from bike discount a while back and picked up some of this.
I’m really impressed – although thin, its cheap, lasts ages, great in the mud, and makes the chain dead easy to clean when you need to. Better IMO than finish line / muc-off / fenwicks.
[edit]
if you look further down you can get some ‘Suspension fork deodorant’ 😯
I use GT 85 and it seems fine. It does wash off in crap weather but it’s cheap enough to reapply every ride and light enough that it wont hold dirt. It’s only a chain after all.
Squirt was alright too but expensive.
I’ve used lots of different ones over the years and the only one I’d never use again is Finish Line wet as it turns my chain into an oily mess.
