Size Guide
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

Cancelled / Refunded Orders Prior to Despatch

Occassionally our site will state that a particular item is in stock & avaible for despatch, when in fact it isnt. This is a unfortunate feature of our ecommerce system & the way our supplier SIM's operate and is beyond our control. As a result your order may be cancelled without prior notice if a solution cannot be found in good time. When this happens we will endevour to issue you a full refund as quickly as possible. Please check your emails for notifications on the status of your order. We will accept no responsibilty for emails dropping into spam folders or going un-noticed.

Garmin HRM-Tri Rate Transmitter Strap

Brand:Garmin

Code:GMS99709

Enhance your triathlon experience by pairing HRM-Tri with your Forerunner® 920XT1. The HRM-Tri stores heart rate data when underwater, then forwards it to the 920XT. Our smallest and lightest module fits within the width of the strap. Its soft, rounded edges and covered seams make the strap super-comfortable out of the water, too.

Running Dynamics

HRM-Tri also has an accelerometer in the module that measures torso movement to calculate 3 running metrics:2

  1. Cadence — the number of steps per minute. It displays the total steps (right and left combined).
  2. Vertical oscillation — the bounce in your running motion. It displays the vertical motion of your torso (measured in centimeters). HRM-Tri is compatible with several other fitness products but will only display heart rate when paired.
  3. Ground contact time — the amount of time in each step that your foot spends on the ground while running (measured in milliseconds).
