Today I found a new Ass Savers mini rear fender. It's flat and made out of a piece of sheet plastic. I would never buy one. Anyway I stowed it away and when I got to the top of the climb up Montebellow Rd I followed the instructions printed on it, and installed it. The weather was drizzly and so it was a good thing to have. It worked great! I would've had a dirt stripe on my ass from the mountain bike trail descent. Weighs hardly anything and better than nothing if there is rain. This sounds like an advertisement. No. I think you could make one out of big a plastic bottle or something. Now I'll need to dig up one ofthose matching zip tie on front fenders.
