Friends, I am a 163 cms rider with a 81 cm inseam (very tall legs). A friend of mine has a Pinarello Dogma 65.1 frame which I am considering. The size of the frame is 47". I know this is slightly bigger than what my height would need but because of my tall inseam I am not sure going with a shorter frame would be a good choice. I am not a super fit guy. I am a typical middle aged hobbyist rider. 46.5" is the typical frame size suggested for riders of my height but here I am looking at a 47.

The primary area of concern with the 47" frame is the reach. So, is it possible to make the cockpit compact enough to fit me ? Zero setback seatpost, short reach handlebars and slightly shorter stems. Will all this do the job or am I being too ambitious trying a 47 frame ?

I am banking upon the fact that it has a high head tube and with enough spacers I will be in a comfortable position for long rides. For an inseam of 32" (81 cms) the typical frame size suggested is actually 51.5 but that will be too big considering my height, so I am thinking a 47 might be a good compromise. Need your inputs on this before I proceed with the build.

Go to a professional bike fitter. Tell us where you live and someone on this board may be able to recommend you one.
I think you have long legs but I won't have a clue if this is out of the normal range. With long legs it's probably not the best to have zero setback and end up sitting too far forward. You probably have big feet, and will get toe overlap. Get off getting internet advice and find a fitter! :smartass:

Based on the very limited facts it *should* fit.

Thanks. I live in Singapore. I can visit a bike fitter here. Would it make sense to visit a fitter without having the bike ? Sorry, I have never visited a fitter hence this elementary query.

Is it your first bike? You can't compare stack and reach of the frame to what you were used to? In principle - if you need more stack (you need spacers) than sizing up may work for you well. You can buy super compact handlebars with short reach..
Regarding bike fitter, some work with a special bike that quickly changes its dimensions so you don't need your own. But he won't be able to set yours, you will need to adjust it according to numbers he tells you. And few mm matters to some..but not a big deal, you may still adjust your position after bike fit a little, for basic info if the bike may fit you it is ok.

No, it is not my first bike. I already have a Pinarello Paris Think 2 in 46.5 size. Its steerer tube is chopped to minimum so there is no scope to add spacers. The only option on it is to use a very steep angled step. That would spoil the looks of the bike and also there is only so much to play around with the stem. I will still be visiting a bike fitter with my current bike and try to get some measurements done.

Could you name some super compact handlebars with short reach ?

I visited a bike fitter and got some measurements done. As per the measurements, either I need to change the seatpost to a zero setback one or I will need to use a very compact handlebar with a 80mm stem for the near perfect fit I am looking for. Another option is to use a Campagnolo groupset instead of Shimano. Campy hoods have 10mm less reach so I can use a 90mm stem with Campy groupset. But the bike fitter (who also runs a bike shop and sells both Campy and Shimano groupsets) advised me to stay with Shimano as much as possible. He said Shimano has that fit and forget reliability, it is smooth and does not go out of alignement. According to him Campy users are always tinkling around with the groupset because it doesnt fall into place like a Shimano does. So Shimano seems to be a better compromise there.

Unfortunately the price of a Dogma 65.1 zero setback seatpost is quite prohibitive (as per the online prices I see) so I want to try all other options before investing on the seatpost.

This handlebar is great: http://ax-lightness.de/en/cycling/bike- ... 4200-ergo/
but it is expensive and rare to find.
Are there other alternatives for a super compact handlebar ?

:smartass: I advised you to go to a fitter and you wisely did. But bollocks to him because I'm a Campagnolo fan: you only need to read some of Calnago's entertaining recent posts to be convinced that Campagnolo is simply the best :wink:
Surely your fit result of 90 stem is not based on that expensive 66 reach bars! I think you need to spend your time more wisely on the internet looking at handle-bars.

I think some Zipps are also around 70mm.
Campy needs to be installed by a Campy specialist, it is sensitive for cable length etc.

wise words .... you can pop into any bike shop and get Shimano spares off the shelf ..... Campy, you have to order on line

plus ..... Campy parts are overpriced.

For the short reach bars, I have shortlisted the following:
1. Zipp SL70
2. SATORI X-RACE AERO Carbon
3. Easton SLX3

Would anyone know which of them would have the shortest "effective" reach ?

Deda has some handlebars with 75mm reach. For example the Superleggera.

Pro (Shimano) Vibe Stealth Evo handlebars have 69mm reach:
