Quick question, front mech clamp size ?

On a 92 GT Bravado

 

[RobMac]

Vernier caliper round YOUR Bravado seat tube OR get a big adjustable spanner open it & slid it round your seat tube, then gently close it, then gently pull it off then measure the gap on the ad/spanner.

Or wrap a tape measure around it, thin tailors type.

Whats that gonna do the clamps are sold by diameter not circumference?

circumference and diameter are related , figured I wouldn't need to mention that.

even a bit of paper and a mark and a normal ruler.

google maths will do the hard work there if you cannot find a calculator in the start/whatever menu of your computer/phone just type 90 / pi into the search area, or even into Chrome's address bar, for example.



and tape not tap and tailors not taylors.

Yeah I did know that but Im crap at maths.
Its just that my idea is easy.

It's also what I would do, but you need to have a 28 to 37mm adjustable spanner or a vernier calliper handy. (

I just figure paper and ruler (or the misses tape measure) would be more common.

Maybe I should be seeing if there is an app for it though.

 

[RobMac]

I did as you said I Googled it.

To find the diameter, divide the circumference by pi
75 ÷ 3.14159 ≈ 23.87 mm
I just took a random circumference of 75mm to try it.

Still think my way is easiest

Have a big adjuster that should go to that size , will try it later.

Pretty sure its 28.6 as the seatpost is 26.8.
