Bontrager NCS Fender Set
We designed the Bontrager NCS fender set to give you maximum protection without the bulk of traditional fenders. The quick-mount system lets you install or remove both fenders in under two minutes, making them perfect for riders who want coverage when weather turns but don't want permanent hardware.
Our engineers focused on coverage where it matters most — the front fender extends lower and wider than our previous models to keep water and debris off your feet, drivetrain, and lower frame. The rear fender's swept profile shields your back while maintaining clearance for wider tires up to 45mm. Both pieces use a flexible composite material that resists cracking in freezing temperatures yet stays rigid enough to prevent wheel contact even over rough terrain.
What makes the NCS different
Materials & construction
We chose a proprietary composite polymer for the NCS fender shells because it delivers the right balance of flexibility and strength. Unlike brittle plastic fenders that crack after a season of cold-weather rides, our material maintains elasticity down to -20°C while providing enough rigidity to prevent flex when water hits at speed.
The mounting stays use powder-coated aluminum with integrated adjustment points that let you fine-tune fender position without tools. Each stay locks into place with a spring-loaded cam mechanism — you simply squeeze the release, position the fender, and let go. The system holds tight over rough roads yet releases instantly when you need to remove the fenders for transport or storage.
Installation & fit compatibility
Frame compatibility
The bontrager ncs fender set fits most road and gravel bikes manufactured after 2015 with disc brakes. Front installation requires fork eyelets or crown clearance of at least 15mm above your tire. Rear installation works with seat stay bridge mounts or seat tube eyelets — we include adapters for both configurations.
For bikes without dedicated fender mounts, our P-clip adapters (included) attach to tubes from 25mm to 35mm diameter. The front fender installs via fork crown mount plus dual stay attachments at dropout eyelets. Rear mounting uses seat stay bridge or seat tube eyelet as the primary point, with chainstay stabilizers preventing lateral movement.
Coverage & weather performance
The front fender extends 340mm along your tire’s arc with a 65mm width that captures spray before it reaches your feet or frame tubes. Our testing in wet conditions showed the NCS design reduces lower leg moisture by 87% compared to riding without fenders, and by 23% compared to our previous generation model.
Rear coverage focuses on protecting your back and preventing road spray from coating your drivetrain. The 380mm length follows your rear wheel’s arc while the integrated tail flap adds another 60mm of coverage — critical for keeping spray off riders behind you in group settings. The swept profile directs water away from your saddle and seat post while maintaining clearance for frame-mounted accessories like blinky lights or saddle bags.

Questions about the NCS Fender Set
Yes, we include P-clip adapters specifically for bikes without dedicated fender mounts. The adapters attach securely to frame tubes between 25mm and 35mm diameter. Installation takes slightly longer than eyelet mounting but provides equally secure attachment. Check that your fork crown has at least 15mm clearance above your tire for front fender installation.
Absolutely — we designed the NCS fender set with disc brake clearance built into the stay positioning. The mounting hardware sits outboard of disc calipers and rotors on both front and rear installations. Thousands of riders use these fenders on modern disc brake road and gravel bikes without any interference issues.
The complete bontrager ncs fender set weighs 185 grams including all mounting hardware. Traditional full-coverage metal fenders typically weigh 350-450 grams for a comparable front and rear set. You get similar weather protection at roughly 60% less weight, which matters for riders who prioritize performance alongside practicality.
The rear fender is compatible with most seat packs and saddle bags since it mounts to your seat stay bridge or seat tube rather than under your saddle. The front fender stays attach at fork dropouts and crown, leaving your fork blades clear for cargo cage mounts or anything bags. Some oversized frame bags may contact the rear fender depending on bag size and frame geometry.
With practice, you'll install or remove both fenders in under two minutes. First-time installation takes 5-10 minutes as you dial in the optimal position for your specific bike geometry. After initial setup, the cam-lock mechanisms let you squeeze and release each mounting point without tools. We've had commuters tell us they swap fenders on and off daily based on weather forecasts.
Properly installed NCS fenders run silent over most terrain. The cam-lock system holds mounting points tight enough to eliminate rattle. The flexible composite material absorbs vibration rather than amplifying it like rigid metal fenders. Some riders add small rubber shims (not included) at contact points for absolute silence, but most find the fenders quiet enough straight out of the box.
The NCS fenders accommodate tires up to 45mm measured width. Beyond 45mm you may experience reduced clearance that risks tire contact during frame flex or when hitting bumps. Riders using 28-35mm road tires get maximum coverage, while gravel setups with 38-45mm tires achieve full protection with slightly higher fender positioning. Measure your current tire width before ordering to ensure compatibility.
