Wrist bands
 

Just a general question.
I have just noticed lately some race bikes with a wrist (sweat) band around the brake reseviour.
Whats that all about???

I thought it was just to mop up any fluid that might leak out of the cap....

Yep, you got it.:)

They'll be putting leg warmers on the termis next...:o:P:lol:

They are there to soak up any fluid that leaks past the diaphrams when the fluid heats and expands after repeated hard use.
