Pinarellos anyway come with a 15mm topcap, while my current topcap is 7mm, so Pina 53 with 14.2+15mm is same as mine which is 15 headtube + 7mm topcap.
Just got a mail though and the 53 is no longer in stock in the deal price, they have the 54 with a 135mm stem. If they can get me a 100 stem I'll buy it, else I'll start looking again.
Issue is shipping to India means 250 dollar shipping PLUS 45% duty, so I need to look where someone ca carry it back for me. Otherwise a 3000 dollar bike becomes 5K landed.
