No grips? You're nicked son

Speaking of gear ratios, I was on a cyclecross web site and found this dude who's bike is running two chain rings up front and 8 sprockets in the back, but both the chain rings are the same size as are all 8 of the sprockets.

Worlds weirdest single speed?

Huh? but why? spread out the wear so you have to change sprockets 8 times less?
