This is a fine selection of Shimano movies, marred, as ever, by the endemically insincere voiceover by their stock commentator. His voice confuses me - I don’t know whether he wants me to buy baby soap or to vote for Mitt Romney.

The spooky, hypnotic, ‘Trekking Film’ is like a cut from The Stepford Wives - you can’t help wondering about the seething lust, simmering jealousy and burning hatred, all boiling under the surface of the seemingly placid four-person peleton. Will it end in a brutal, cold-blooded, murder, a frenzied, desperate, orgy or a suburban TV dinner featuring organic broccoli?

As for the dude demonstrating ‘Shimano Shadow RD Installation’, he delivers a terrifyingly convincing portrayal of an automaton. I suspect that he’ll be back... possibly as Governor of California.
