Questions we get asked most
When will my Strap arrive?
Every Strap on this page is a pre-order. Dispatch starts on .
Which band comes in the box?
One AirKnit elastic band in Midnight Dark, in a single size. It is stretch knit with no buckle, so there is nothing to measure or fasten. The S-M and M-L sizes you see on this page belong to the FlexKnit band, which is a separate add-on.
What is the difference between AirKnit, FlexKnit and the Armband?
AirKnit, 40,00 €. Stretch knit, pulls straight on, one size, no buckle. This is the band already in your box.
FlexKnit, 50,00 €. Fastens with velcro and stays put through heavier training. Two sizes.
Armband, 40,00 €. A 380mm band that moves the Strap onto your upper arm instead of your wrist.
All three bands are sold out for now as add-ons.
Which FlexKnit size should I pick?
Measure around your wrist bone. Under 160mm take S-M, over 190mm take M-L, and anywhere between the two either size will fit. S-M covers 135 to 190mm and M-L covers 160 to 230mm.
Which version can I order right now?
Both the Standard and the Pro are available to pre-order.
Is there a discount on more than one Strap?
Yes. The Strap drops as you add more: 10% off two, 15% off three, 20% off four or more.
Do I need a subscription?
No. Twenty-four hour heart rate and HRV, sleep staging, recovery scoring and automatic activity detection all work without one. Wellness+ is a separate optional subscription that you buy and manage yourself in the Speediance app, and it is not included with the Strap.
Where do I wear it, and does it replace my watch?
On your wrist. That is the position the sensor is designed and calibrated around. The Strap has no screen and is not a watch replacement, so there are no notifications, no calls and no GPS, and most people keep wearing their watch alongside it. If you would rather wear it higher up, the 380mm Armband is made for the upper arm.
