The Mamba pedals from Funn are super durable and suitable for all types of mountain bikes. With a double or single clip-in mechanism on a large platform, the final design of these pedals was heavily influenced by Funn's test riders in the field. Mamba pedals provide instant engagement and increase pedal efficiency, allowing you to boost your speed and confidence as you race over trails with great precision and stability. Mamba pedals are compatible with SPD (Shimano Pedaling Dynamics) cleats. With the Grrs system (Grease Renew System), you can refill grease without getting your hands dirty.
