Size and Fit: Unexpectedly Compatible
I ordered the 45mm width Planet Bike Cascadia fenders, but received 35mm ones. Surprisingly, they still fit perfectly over my 700 x 37 Continental Travel Contact tires. This was unexpected, but a positive surprise. The fit is snug but not overly tight, leaving plenty of room for tire clearance.

The slightly smaller width didn't affect functionality, and the installation process was surprisingly easy despite the size difference. There's ample space between the fender and the tire, suggesting the advertised 45mm may be an overestimation.

Performance in Wet Conditions: Excellent Protection
The real test was riding in wet and muddy conditions. These fenders kept me completely dry and clean. The difference was remarkable compared to previous rides. I stayed significantly warmer too. The added protection against splashing mud and water is a clear advantage.
Furthermore, the fenders efficiently kept the drivetrain cleaner; significantly reducing the usual post-ride maintenance required. This feature alone justifies the purchase for the protection they provide.
Installation: Easy and Versatile
Installation was straightforward. Even though I had installed fenders before, the process was simplified by the well-designed components. The included hardware was sufficient, including extra pieces for different bike setups.
The instructions weren't necessary for me, but for first-time users, a quick YouTube tutorial is advisable. The fenders' adaptability and the easy installation are key selling points.
Durability and Adjustability: A Solid Build
The fenders are made from sturdy stainless steel and are very durable. They stay firmly in place with minimal rattle. There's plenty of adjustability to ensure proper alignment and fit, which is crucial for optimal performance.
I especially appreciated the standoffs provided for disc brakes. The adjustability allows customization for various bike frames and tire sizes. Although some minor adjustments required additional zip ties and bolts.
Minor Issues and Overall Impression
While largely positive, adjusting the fenders initially proved slightly challenging. I also lost a bolt early on, but Planet Bike promptly sent a replacement. Minor issues with rock accumulation beneath the fenders were noted.
Despite these minor drawbacks, these fenders are a worthwhile investment. The exceptional protection from the elements, coupled with their ease of installation, outweighs the minor inconveniences. I wouldn't hesitate to recommend them.
