Fail again - they are T1-sports, not T1-R. Thats exactly what my problem has been which is why I didn't appreciate anyone getting arsey. I have always run the same shoes in all four corners but in this case it hasn't been instantly possible.
I have got one for £202 which I have no problem with. Issue wasn't finding one cheap, it was sourcing one from a company that didn't want to to charge me in excess of £350 for one tyre.
