With winter fast approaching, I want to get a set of 'guards for my Orbea. Only trouble is, it has neither the mounts nor the space for normal fenders. I'm sure others must have this problem and there is surely a solution, but what is it and how much will it cost me? I want to spend as little as possible, and I have limited tools here at uni, so something with zip-ties or similar would be nice (if there is such a thing). Having said that I do have a full set of allen keys and screwdrivers, which covers most possibilities. I will of course need front and rear fenders, even if they are a bit on the small side (I really just want to keep the spray off my back and legs).
