It's only fair. I get an accessory for my bike in the Hugger. Mr. Oilburner gets this pretty little fender extender. It seems to serve the same purpose as the Hugger: prevent rock flingin' from the tire. His little extender is more for the benefit of others riding or driving behind. Mine is a little more selfish in mostly protecting my shock. His is plastic, mine is carbon fibre. His cost $39 US, mine was only 8 times more. :) I think it's fair.
The installation looked difficult and even came with an installation manual. (?!?!)
Insert extender into the existing fender.
