Choosing for your commute
Clip-on mudguards can make an existing road or gravel bike more useful for commuting when rain leaves the road wet long after the shower ends. They intercept some of the spray thrown by the tyres and can reduce how much reaches the rider. Their appeal is strongest on bikes without conventional mounting eyelets, or where you want removable wet-weather equipment.
This is a compatibility purchase. Start with tyre width, wheel size, brake layout and the shape of the fork and rear stays. The model name alone does not establish fit: Raceblade Pro XL and Speedrocker cover different tyre ranges. Leave appropriate clearance and follow the fitting instructions, then check security and wheel rotation before riding. A small rear splash guard and a front-and-rear set also offer very different coverage.
