In all my 20 years of riding, I still don’t get why people feel the need to re-lube during a ride? I’ve either never ridden far enough or I’m so deaf I can’t hear my drivetrain whining at the lack of lube? Or are there other tell tale signs?
Or perhaps the lube is slathered on so thick, I have no issue?
I just apply wax stuff (Squirt or White Lightning Clean ride) over and over again and it gradually builds up. It does need applying well in advance of a ride though so that it solidifys.
Only time I re-lube is after a wet ride or on the first tell tale signs of a few spots of rust.
So far as Purple Extreme or similar – if its all meant to be wiped clean after you apply it, how do you tell when you need to re-apply?
