Customers should review the individual product page before placing an order.

Product appearance.

Color, finish, fabric appearance, surface texture and packaging may vary slightly because of photography, screen settings or normal production variation.

Compatibility may depend on bicycle geometry, handlebar dimensions, seat-post or saddle configuration, rack setup, frame shape, mounting points and other equipment.

Customers should review available specifications before purchase where fit matters.

Customers are responsible for installing accessories according to their intended purpose and available instructions.

Mounts, pedals, grips, bags, bottle cages and other fitted accessories should be checked for secure attachment before riding.

Saddles, grips and pedals may feel different depending on riding position, bike setup, route conditions and personal preference.

Bags and carrying accessories.

Customers should avoid overloading bags, baskets or mounting systems beyond the ordinary intended use of the specific product.
