I just got one of these DRC extension hoses Robbo, see this link
He does the angle extensions too, and pretty reasonable with his prices.
Cheers
Thanks for the replies fellas, I think I'll go for the hose extension and then when tyre needs changing have a 90 degree valve stem installed through the rim by me tyre man.
Bloody crappy design, I have heard the 2018's have been rectified.
