Some of you might know that I have been looking at the Volpe for light touring and I received a lot of help here for that. Unfortunately I got a rude shock from the Bianchi India dealer [who had said he would get me the bike by Dec] yesterday, saying that they will be UNABLE to get me the bike at all.
So I started a search again, and a Singapore dealer is willing to ship me a LHT. I had thought of a 52 but he recommends a 54.
My height is 5'8"
PBH is 84.5 cm or 33"
My current road bike is a 50cm Cannondale CAAD9 which is pretty aggressively set up. The Eff TT is 52.5 and I have a 100mm 5* stem [stock]. Reach is fine and fit is good but the saddle to bar drop is 4". The head tube angle is 72.5*. The head tube length is 11.5cm.
My previous bike was a Trek 52cm with an eff TT of 53cm and that was also a good fit.
Now, the LHT in 54 has an Eff TT of 55.5cm and a head tube angle of 71*, so I think with the 17* stem and the taller head tube, and the bar being at saddle height or thereabouts, my reach should be about the same in the 54cm LHT as the 50cm CAAD9? Head tube length of the LHT is 18.2cm.
I actually did a mock up of a setup like this and I found that even with an eff TT of 3 cm more, with the bar higher and closer because of taller head tube, the bar to saddle distance will be reduced by 3cm compensating for the increased TT length that the LHT will have compared to my Cdale.
Standover height is 79.3cm for the LHT.
I have done a search and probably read all the posts regarding LHT sizing but this is a specific question regarding reach. The Rivendell site says its better to go larger with touring bikes and also explains how the reach becomes less as the handlebar rises. Have also seen the LHT sizing spreadsheet but that really is not very conclusive.
Really would appreciate help here.
