Winner, Bikeminimalism Awards 2012, product of the year ( “. . ., proved itself in use on thousands of bicycles around the world.) Fits on the saddle rails. Will not fit Brooks saddle. This little wonder, hides underneath your seat (if you are so inclined or just keep it in your backpack, kit pocket, etc), and can be deployed in a matter of seconds. The fender has cut-outs to allow it to grab the rails. It bends down the length of the fender to make it rigid.
If you order one from the manufacturer, you have to pay shipping of about $5.00 with a base cost of about $10.00. Here’s what “road.cc” had to say. “The San Marco Ass Saver is a simple and reasonably effective solution to keeping spray from soaking your bum when riding rain soaked roads. If you can’t, or don’t want to fit traditional full-length mudguards to your bike, and most racing bikes won’t take them, this is better than nothing.”
Here’s what Janet K., an amazon customer had to say (she paid $14.99). It works great! I did need to trim it to fit my seat length since it was just a tad too long. Love it and bought two others as gifts! And pro teams are using them. This from the asssaver manufacturer’s web site.
“The conditions were horrible for the riders who participated in the epic Milan-San Remo this year. Wind, snow and rain for almost six hours. Horrible for riders but perfect conditions for the Ass Savers debut in pro cycling. Our friends at Selle San Marco made it happen and both the Lotto-Belisol team and Vacansoleil-DCM team were sporting Ass Savers during the race, . . .
” You should go to ass-savers web site and there they will have all the gory details, including a video. Search for other listings and you’ll see I am much more competitively priced. Right now, I have black, grey and transparent.
