Where can I find current product details?

Review the individual product page for current images, included components, available options and pricing.

Will every accessory fit every bicycle?

No. Compatibility may depend on bicycle design, dimensions, mounting points and existing equipment. Review the product information before ordering.

Standard U.S. transit is generally 10–15 business days after dispatch.

Will I receive tracking?

Where tracking is available, tracking information may be provided after dispatch.

Why has tracking not updated?

Tracking may update slowly. A temporary lack of activity does not necessarily mean the shipment has stopped moving.

Which payment methods do you accept?

Payment methods may include PayPal, Visa, Credit & Debit Cards, Apple Pay and Google Pay.

Can I use PayPal?

Yes, when PayPal is displayed as available during checkout.

Can I use Apple Pay or Google Pay?

These methods may be available depending on device, browser and checkout configuration.

Why was my payment declined?

Payments may be declined because of issuer authorization, billing-information mismatch, provider restrictions or security checks.

Can I change my order?

Contact customer support as soon as possible. Changes cannot be guaranteed after processing begins.

Can I cancel my order?

What if my cycling accessory arrives damaged?

Contact customer support with your order details. Photos of the product and packaging may be helpful.

What if I receive the wrong product?

Contact customer support and identify both the ordered product and the item received.

What if part of my order is missing?

Review available tracking information first, as some orders may arrive separately. Contact support if the order still appears incomplete.

What is the return window?

Eligible return requests may be submitted within 180 days after confirmed delivery.

How do I request a return?

Contact customer support before sending anything back. Approved instructions will explain the appropriate next step.
