Went into a shop when visiting a nearby city. Was at the time weighting up getting a c59 frameset, and although all the geometry is available online, wanted to double check C-T of the seat tube, as from the graphic online, it looked like it went to the bottom of the seat clamp instead of the top of the seatclamp.
Only wanted this measurement just for seatpost selection, as I wanted classic geometry, and wanted to get it all proportionally to 'look right'. Also wanted to double check headtube length, with also checking top cap measurement (as I wanted to go with a -17 stem to complete the classic looks).
Anyway, walked into this boutique store, asking to have a look at one of the frames. Asked if I could use my dressmakers tape measure, to measure the dimension I wanted to check.
Guy, goes, 'what do you need that for'. I say, 'just need to check because i'm planning on building a bike based on this frameset, and I want to get the size right'.
At this point, he looked at me stupid, and I realised I had said something stupid, as he didn't understand why I would want the measurement. So he says, 'do your reach and stack'. And i'm like, 'no, not offhand, but that doesn't matter anyway. I'm using the geometry chart online, I know what size frame i'm after'.
He then proceeded to tell me 'oh, they are unreliable, you need to be fitted', 'here jump on this bike, and see how it feels'.
Now that was funny... Colnago producing $5000 framesets, and their own online geometry chart is _wrong_? LOL
It was thus my turn to look at him like he was stupid.
Anyway, jumped on the 48 sloping that was set up on a trainer, and had a quick pedal in sneakers.
'see', he says, 'that's probably the right size'...
I'm 5'11... and the bike had about a 10cm stem, and compact bars. It was essentially 2 sizes too small, though, I reckon I could get on a 50s with a 13cm -6 stem and classic drop bars.
I was like, 'err, yeah ok, but I think I just want to check the 2 measurements i'm after'.
At this point, he finally just let me do a quick measure, and I was done.
Talked for a while longer, then I made my getaway
I know now I won't be getting a c59 now due to it being replaced by the c60, and with it's pressfit bb, I won't be buying one.
