I was in the same predicament a while ago. Managed to find a engineering workshop close by that had the right size. After seeing there tap collection I doubt there is actually any size and pitch they couldn't cater for.
The yellowish colour tubless specific tape. Unfortunately comes on big rolls around R400 but at least it lasts a while. It's far better than duct tape for both mtb and road.
The only thing that put me off about this unit was the sealed battery design. If something goes wrong it would appear it's basically becomes a paper weight. But for the price I was prepared to take the risk.
Will have to wait and see it it gives issues. Hopefully by then you would have sorted yours out.
I just checked on mine. Once I spin the crank to wake it up the green led pulses every 5s or so. Then turn on cell phone Bluetooth and it finds it. Not sure if there is a hard reset available as everything is sealed on these units.
Else :
. Turn the crank to make the power meter wake up and the LED
will twinkling blue.
. Search and connect the power meter on the bike computer.
. Connect the device named XPOWER-S XXXX if using Bluetooth.
If origional owner and bought it locally you could perhaps get it warrantied. Think Black Marlin are the distributors. Or try log a fault with them see if they can suggest anything. https://xcadey.com/xpower-s-replacement-service/
Does the led on the unit come on ? I know of someone that had problems charging the unit turned out to be a bad connection between charger plug and spider.
You will pay local UK tax on the product. Then when it gets couriered will pay SA imports and local taxes on the couriered parcel at the amout declared. So normally this is not really a good option.
If I had the choice I would build a set of Nextie Rims with DT Swiss 240 hubs or Aviee light weight Hubs. Doubt any local rims will be able to compete.
When I have had issues with them before a quick complaint on Hello Peter seemed to have sorted the problem out rather quickly. Looks like Andrew reads the comments on that platdform regularly. However emailing him directly would probably get an even faster response.
