Cheers Andrew, I was in GBs yesterday and I thought I saw a Conti sprinter but wasn't sure. I was looking at their website for the prices and the sprinter wasn't listed. I will have a look in GBs tommorrow when I am back at work.
Thanks for the offer of the wheel I am guessing you haven't seen the start sheet, you are off at 6.41 and I am off at 7.22. I will have a new tub by then by hook or by crook.
Strangely while waiting for the tour to start I found that DeVer cycles which is near to work as well has a Schwalbe tub in which is about the same spec at the sprinter and about the same price. Looks like I am not going to get much work done tomorrow
