Bobbin & Sprocket. They can be crocheted in different patterns, according to your specifications (you can see them here on Bobbin & Sprocket's own bike and here on an ANT bike). I ordered a set for my mixte a couple of months ago, but have yet to attach them - because I've decided to do a drilled-fender installation, rather than use the clips provided. The clips don't attach securely enough for my fenders - and I am weary of having the guards fall off and get tangled in my wheel spokes. Earlier, I reviewed the Dutch Simeli dress guards, and clip and fender compatibility was also a problem (they only work on bikes where there is a lot of room between the fender and the tire).
simple set of dress guards that a reader had sent me from Portugal. The fancy ones in the picture above were a gift from a friend in Autsria, and are waiting for the right bicycle.
ANT, who has recently begun to order them from Europe. They are simple, stretchy and durable, and I thought the colour scheme suited my Gazelle nicely. Drilling fenders for dress guards may seem like a daunting task, but the actual act of installing them is not difficult, if you have a good drill. What's difficult is making the commitment: You can't "undo" the holes in your fender once they are there, and nearly every set of dress guards requires a different number of holes.
I would also suggest using a fresh drill bit and having a spare one before you start, in case it breaks.
this post. Looking at the final result, one could say that these guards could look better if they were fanned out over a wider area - but I wanted the coverage to be denser. It's really a personal choice, and I am pretty happy with how mine have turned out. If you own a drill, this method of dress guard installation is worth considering.
