Shimano develops innovative test to ensure its parts will work in UK conditions (video)

It's no secret that we have our fair share of rain in the United Kingdow, with much of the north of England and Scotland still recovering from the effects of Storm Desmond.

For us cyclists that means we've got to know that our bikes and components can face up to the rigours of riding in such changeable weather, but luckily Shimano has our backs.

Triathlete duo Romain Guillaume, of France, and Scotland's David McNamee tweeted a video of themselves doing this rigourous testing, which involved riding their lovely BMC triathlon bikes into a large swimming pool.

Success! We don't have to worry about the rain getting in our Di2 any more, these guys have got it all sorted out.

Obviously Shimano has a few more rigorous tests up their sleeves to ensure their components work under the most extreme pressures, so these triathletes' experiments probably aren't fully representative of the full testing process. But it's fun, nonetheless.
