84 Saddle height preferred -
Sat on M/L and with uncut mast at 78, to top of seat was 82 before any spacers. Hands on hoods and looking down through center of front hub. Compact cockpit. Arms bent. Head tube 17. TT 57
Sat on L and with uncut mast at 79, to top of seat was 83 before any spacers. Hands on hoods and looking down with hub 1" back of handlebar. Arm straight. Head tube 18.5. TT 58.5
Sat on XL with uncut mast at 82, to top of seat was 86 before any spacers. Hands on hoods and looking down with hub 2" back of handlebar. Arms and torso very stretched out. Head tube 20.0 TT 60.5
We seemed to rule out the XL due to really stretched out position, but will ride all three if I wish tomorrow.......what should I look for assuming same saddle height? Only reason I could consider the M/L was due to uncut seat mast allows for proper saddle height for my legs. Because of relatively long arms and short torso, the drop did not feel much different between the M/L or the L. Suggestions to consider? Looking at SL 1 or 2. 1 is DuraAce mechanical, 2 is Sram Red.
The three I compared, the M/L, the L, and the XL were great bikes, but I am just all legs. The appeal was Giant's ISP and uncut from the factory leaves quit a bit to work with for the seat tube.
My usual problem is many fitters gravitate to an XL, but with longer top tubes I am stretched out and either have to go with dramatically reduced stems and forward seat positions or settle to just be stretched out. Had a Madone 6.9 62cm but got tired of reaching all the time and did not like the feel of shorter stems so I sold it.
Flexibility is not an issue, so the drop is not a problem on any of them. Mainly wanted a tighter cockpit with the correct bend in the elbows and 90 degree arms at the shoulders. The Giant was one of the few that offered a choice on that with long uncut ISP to provide the seat tube length for the legs in an all carbon frame. The middle one, the large, weighed 14.1 lbs complete w/o pedals at the one shop I looked at today with average wheels.
Have done the custom stuff years ago, but the compromise was the weight. In this case, wondered about others with their observations on the Giant geometry and where to make the compromise.
I haven't kept up with all of the different ISP posts, but it doesn't make sense to me to look at any frame that would require an uncut post, with spacers on top, just to get the proper saddle height.
Getting on stock frames with whatever stem length and angle they some with and looking at how the bars line-up with the hub is not a proper method of comparison. You should know what your preferred saddle setback is, adjust the height and setback first, then measure from the saddle nose to the center of the bars, to at least get a reasonable idea of how that value compares to what you have been riding.
I would think that only the L or XL should be considered. With that in mind, the reach difference is about 1.5cm.
Since you've owned a Madone, I can also tell you that XL size Giant won't have a shorter reach.

I'm a big fan of Giant bikes btw. Long time cyclist and after testing a lot of other brands immediately preferred the Giant during test rides.
