The SM-WB13 is a completely newly developed bike transport bag designed for improved user-friendliness and portability. It accommodates tire widths up to 45C and allows for the transportation of bikes while securely protecting the axle and brake disc. The base plate features a non-slip material that ensures stable standing and reduces the risk of tipping over when the bag is leaned against a surface. Inside, a new marking on the brake disc side provides immediate visual orientation to prevent incorrect alignment of the bikes during storage. The bag is also equipped with hooks at both ends, where a shoulder strap can be attached to facilitate transport to races or training trips. A large inner pocket offers ample space for storing tools and small parts, making this bike bag an extremely functional and practical companion.
