If you want to stay as dry and clean as possible when riding your bike on wet roads, get yourself a proper set of full fenders - it's just that simple. There are a lot of cyclists, however, who feel that fenders make their lean, mean, street-ridin' machines look boring and clunky. Additionally, many types of fenders have an annoying way of rubbing, rattling, or just plain getting in the way. While some quick-on/quick-off systems do already exist, most of them still incorporate permanent mounting brackets, or are made from thin plastic that has a tendency to droop. Full Windsor's QuickFix plastic mudguard, however, slides in and out of place within seconds, yet still looks like it's reasonably substantial.
The QuickFix has an origami-type design, so it can press flat for storage in a bag when not needed, yet folds into shape when mounted over the bicycle's rear wheel. Its on-bike shape not only helps it contain the upward spray of water and road gunk, but also gives it some rigidity.
The mudguard attaches to the seat tube using marine-grade metal snaps, then runs back between the seat stays (over top of the seat stay bridge), where two more sets of snaps hold it in position.
If you think that the QuickFix looks half-decent, and wouldn't mind having it on your bike full-time, you might instead look into the company's Foldnfix mudguard. It's very much the same idea as the QuickFix, although it attaches more permanently, using nothing other than zip ties.
Both products are currently available through three UK bicycle retailers, listed on the company website. The QuickFix sells for GBP14.99 (US$23.90), while the Foldnfix goes for GBP13.49 ($21.50). Full Windsor is currently seeking international distributors and retailers, should you be interested.
Prospective buyers might also want to check out the Origami Fender, made by Portland Design Works.
Otherwise the design and the idea is cool.
