Hi ,Iv,e got a racing type bike which has looked after me for nearly 20 years. I need to buy some new tyres and tubes but when i tell the young guys at the local shop the size they look at me as if iv'e asked for something really stupid.

The wheel size is 27 inches x 1 1/4 inch .

I'm sure there is a metric equivalent , please help
Thankyou

Not really. 27" is the nominal wheel size and you are stuck withthat bead seat diameter. There are 27 x 1,11/8 and 11/4" sizes. The shop nose pickers aren't old enough to remember 27" but they were really common on lower end bikes in the 70s and 80s. Wally mart still carries some cheapies. Also try nashbar and www.harriscycery.com

I have a set of wheels from around 1984 what were Campy Record Hubs size 27x1 - I do not consider that low end.

Yeah, there are always exceptions. But maybe some idiot built them that way.

Actually I have several set built with Campy hubs. Often used with highend touring bikes and in some cases a sturdy trainer. I went to clinchers back in late 70's I found tubulars to difficult to repair and maintain. Even at 15 (1978) I was pushing 6' so I was big as well. I was fortunate to have such a nice bike but the cost in replacing tubulars was a bit much for me then. I don't consider myself an idiot but rather a visionary since most are riding clinchers now. I still have that wheel set on a vintage Bob Jackson with all campy record and super record components. They still ride great and never went out of true.

Back in the late sixties / early seventies you had to take what you could get : dunlop sprite 27x1,25 and then michelin came up with slick 1 inch that was a joy - mind you as a schoolboy I had no money to spend so had a carlton ( 531 though ), steel rims etc and rode it to and from school twice a day for 4 years in rain or shine ( and ocasionaly in the snow - were we mad or what ! ) good times though - mind you don´t let anyone tell you that england has no hills : what they lack in quality they make up for in quantity , that ride to school was like a jo-jo , up down , up down , up down ....... 😉
