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

2. If we have delivered the correct bike but upon inspection, you decide the bike is not the one for you, we will charge you £50 for collection (£100 from Northern Ireland). If you do not have the original box in usable condition, we will charge you an additional £15 to provide one.

Refunds will be processed using the same method of payment used for the original purchase. Credit & debit card refunds must be made to the card used for the original purchase.

Garmin Index Sleep Monitor in Black

Season:All Year Round

Brand:Garmin

Code:010-03024-SLP

Discover a more comfortable way to track your sleep with the Garmin Index Sleep Monitor. Designed to be worn on your upper arm rather than your wrist, this lightweight, breathable smart band provides detailed insight into your sleep quality, recovery, and overnight health metrics without compromising comfort.

Advanced sleep tracking measures sleep stages, sleep score, heart rate variability (HRV), respiration, and skin temperature to help you better understand your body's recovery. The built-in Pulse Ox sensor monitors blood oxygen saturation and breathing variations throughout the night, while Body Battery energy monitoring provides insight into your energy levels. A gentle vibrating smart wake alarm helps you start your day at a more suitable point in your sleep cycle.

The Index Sleep Monitor automatically syncs with the Garmin Connect app, combining overnight data with information from compatible Garmin smartwatches for a more complete picture of your training readiness and recovery. With up to seven nights of battery life and a removable, machine-washable band, it's designed to make consistent sleep tracking simple and convenient.
