Should You Buy It?

Our expert verdict

The Cannondale Treadwell 27.5 Fender Set earns a 2.5/5 rating—lightweight and purpose-built for select models, but undermined by the 100% negative Amazon review, potential fakes, and compatibility pitfalls. At historical $50-70, value hinges on perfect fit; otherwise, it's skippable.

Ideal for confirmed Treadwell 27.5" owners prioritizing style over ruggedness, especially rainy commutes. Remote town riders get clean aesthetics without bulk. However, dealbreaker for 29" wheels or durability seekers—opt for SKS instead.

Buy if you verify fit and stock returns; otherwise, explore alternatives for peace of mind. Check Cannondale dealers for availability.

Value Assessment

Is it worth your money?

6/ 10

Good Value

Why This Score?

At $50-70, it offers OEM convenience for Treadwell riders but poor value due to single 1-star review, fragility risks, and unavailability. Competitors like SKS deliver better durability per dollar.
