Viner Track Frame Size
 

I bought this frame 5 years ago and built it up. This frame was advertised as a 60 cm. I've been riding it with no problems I'm just curious. I found this stamp on the bottom bracket. Does this mean its a 58cm?

certainly appears a good deal larger than fifty-eight

it may be that the builder grabbed a shell already marked with a "58"

enjoy your Nerozzi!

It likely refers to the angle between the seat tube and the down tube.

Thanks, It is a nice ride and very light

Does the same measurement from top of seat tube to center of BB have the same rule as standard road bike? I will measure that too after work today.

Nice 2 bike stand that is movable. Is it sturdy for 2 bikes?
Like that Viner SS, Im going to guess 62 cm.

Yes, its movable. It holds bikes very solid. It was purchased from Amazon. I ride 60cm bikes. and this fits nice. I just seen the stamp last year and been questioning it.

I wouldn't say there is a standard rule, more like guidelines for the individual countries and the bigger manufacturers. Like the English did inches and center to top. Most Italian did Centimeters center to center.

I know what size! It's my size ;)

There's no real standard; some measure from center of bottom bracket to top tube/seat tube intersection, others from center of bottom bracket to top of seat tube. The difference amounts to about a centimeter or so.

Measured from the top of seat post tube to center line of crank and it was 59ish cm. Most likely a 60cm and the stamp might be the angle as mentioned above.
The purple line is where I took the measurement.

It's an Italian bike, so 58 would indicate the center-to-center seat tube length in centimeters. Which seems to be correct.

My Alan Competizione says 59x58. It measures ~61cm center-to-top:

Interestingly, my Viner road racers do not have a size indication on the BB shell:

Thanks, That makes sense this is my only Italian frame and only track frame.

So would this frame be technically labeled a 58 cm?

In Italy it would. In many other countries it would be called a 60 cm frame (or 59 or 61, depending on the actual center-to-top measurement). To be safe, add a "c-t-c" or "c-t-t" when describing it.

My eyes said 59 c-t (which is 58 c-c as JohnD said). I raced a 59 c-t Fuji Pro. My Mooney was taken from it and most of my bikes since have been very close.

Nice bike!

Yep. Looks like you could barely fit a sheet of paper between the crown and front tire on this bike.

My Viner BB (and steerer too) is stamped with a single digit, "6." Seat tube is 56cm on centers.

This was good stuff! Thanks for the clarification.
