Review on Zefal Swan Road Bicycle Fender: Ultimate Rear Protection in Sleek Black Design by Fuzzhead Nelson

I bought this for my 2018 Specialized Roubaix which is a size 49 and couldn't get it to work with a bike taillight. Since it only has one adjustment point, I was able to either get good clearance with a good fit or see my bike's headlights. By installing it under my bike light, I tilted it up just enough to create a gap so you can't see the bike light, which is mounted all the way under the seat. As a general rule, assume that you need about 12-15 cm (12-15 cm) of vertical clearance from the attachment point on the seat post to the top of the tires.
