Scope of delivery
Stock availability and pre-orders
Most of our items that are in stock are shipped the next business day directly from our showroom at Montpellier.
When the button shows “Add to cart”, it means the item is available immediately in our inventory.
When the button shows “Pre-order”, the item is not physically in stock. We then place an order with our workshop or suppliers. The estimated lead time is generally 15 to 20 days before shipping.
We are a small, dedicated team, and our priority is to offer you the best selection possible, even if that sometimes means we cannot keep every item in stock at all times.
If your order contains both in-stock items and pre-orders, we generally ship everything in a single shipment once all products are available. If you need a different arrangement, feel free to contact us.

CYKL Team Advice
The eRX is a formidable option for cyclists seeking a high-performance electronic road drivetrain without the price tag of a Shimano Di2 or SRAM Force groupset. Its redesigned ergonomics, integrated braking system, and 10-12 speed compatibility make it an ideal choice for a high-end road or endurance build.
