Got a Johnny Watts tyre seems OK I will soon find out I dare say. Shortage of 2.6 only reason I got it . May try a 2.5 next time. Usual fiasco putting on last bit. Broke a leven so left it to get my metal one. Tyre came off again I'm thinking heard the rattle of the wheel falling. Looked like a disaster the cassette had came off some pawls and a few bits lying all over . Turns out only one pawl spring was half broken so easy fixed and test ride all was OK.
