It looks pretty inoffensive doesn't it, nestled next to those soft cushions, but that cylinder of lightweight foam can generate a most exquisite pain, so bad that you even lose the ability to scream.
I can't recall where the idea came from to buy this little monster, but it now comes out after a long ride or series of hard training turbo sessions and laughs a sinister sneer at me before it begins.
Even worse is that I choose to submit to the torture and even have to inflict the intense pain on myself. Anyone else know what I'm talking about?
