I ride a fixed road bike with full SKS guards. Am also looking for a used Giant SCR for winter duties, as this will also take full guards. The raceblades aren’t bad, but nothing like as good as the full chromoplastics. The black ones are almost invisible anyway, and I’ve saved the weight by swapping out other components. I found the lack of rear wheel coverage on the raceblades gave a good soaking from the rear wheel across the front derailleur. And I’m the most popular person on our wet club rides.
I don’t like a mouthful of gritty water or an abrasive eyebath when out in a group.
