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

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

WHAT IS POWERCRANK-E?

This is our newest version of a power meter created with modernity in mind. We have equipped the reliable POWERCRANK-E measuring system with a rechargeable battery, which you charge using the included magnetic USB cable. It’s not just a power measuring device, it’s your training partner thanks to which you’ll enter a new level of sportsmanship. The INPEAK POWERCRANK-E power meter uses ANT+ and BLE transmission protocols to send power, cadence and a host of detailed cycling performance data. The low-profile, waterproof and durable housing is designed especially for road and gravel bikes. Precise and accurate readings of generated power regardless of weather conditions are provided by ATC’s automatic temperature compensation mechanism from -5°C to +50°C.
