## Long description

TOPEAK DeFender M1 is a lightweight plastic mudguard designed to reduce splash, spray and mud contact for rider and bicycle. With overall dimensions of 640×150×85 mm and a monochrome black and silver finish, this single-piece guard can be fitted as a front or rear protector on commuter and city bikes. The DeFender M1 is compatible with 27.5" (650B) and 29" wheels and mounts to standard front forks, including reverse arch designs, using a quick-release attachment system. A highly polished underside helps prevent mud buildup and makes cleaning easier.
Advantages
The DeFender M1 offers a compact, single-piece construction that keeps weight low while providing broad splash protection. Its quick-release attachment integrates with fork crowns and reverse-arch forks without requiring complex tools, and the polished underside minimizes dirt accumulation to simplify maintenance. The neutral black and silver finish suits a wide range of urban bicycle styles.

Key specifications
 Material: durable plastic construction
 Dimensions: 640 mm × 150 mm × 85 mm (length × depth × height)
 Compatibility: fits 27.5" (650B) and 29" wheels
 Finish: black and silver monochrome
 Attachment: quick-release mounting for fork integration
 Underside: highly polished surface to reduce mud buildup
 Unit: supplied as a single-piece mudguard
How to use
Position the DeFender M1 beneath the fork crown or at the rear where it aligns with the wheel arc. Engage the quick-release attachment according to fork type so the guard is centered over the tire and clears brakes and wheel components. Adjust the fore-aft position and angle to achieve optimal splash coverage while ensuring no contact with the tire during rotation. Periodically check the fastening for tightness and re-seat or realign if necessary.
Usage recommendations
For best performance, fit the DeFender M1 as close to the wheel as possible without contacting the tire. Clean the polished underside after muddy rides to maintain low buildup and inspect mounting interfaces regularly. Avoid using the guard on heavily modified forks or setups where the quick-release cannot securely engage.
