Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

The SQlab 613 R Ergowave S-Tube Saddle is engineered for triathletes facing long rides in aggressive forward-leaning positions. Its raised rear section shifts pressure toward the pubic bones, relieving the perineal area and improving power transmission. This also reduces skin irritation and helps prevent protective, fatiguing postures.

Based on 18 years of SQlab research, this saddle balances step height, width, and nose drop to provide the perfect ergonomics for complex riding positions. The design enhances legroom while supporting sensitive areas, allowing athletes to focus on performance rather than discomfort.

Ideal for triathlon and long-distance race applications, the 613 R combines precision-engineered relief, support, and comfort in a lightweight, performance-oriented package.
