I am looking for a new frame, and am pretty sold on the Pedal force deals. I am not a racer, but do ride a decent amount and am looking for a bike that is more laid back than a traditional racing setup. I am currently riding a 1984 Pinarello Treviso with all new 105, if that gives you an idea of what I like... I am 5'5" and looking at the 49 and 50 cm frames.

Which one of these is a better set up for me?

You have not provided enough information. I would need an accurate saddle height to give the best advice.

Most likley, though, you've got short legs to go with your height and the 44cm would be the best size. The 49cm only has a 10mm taller head tube, so the bar height can only go another 10mm higher. The next larger size is a 52cm and that is much too large.

Right you are! Not enough info...

My Pinarello's geo is:
Top tube c-c 52 cm
Seat tube c-c 49.5
Cockpit from c of handlebars to c of seat post is 59cm
wheel base is 965cm

This is a pretty comfy bike, would one of these Pedal Force frames be a total shock for me, or will it feel familiar?

I assume you want a bike that does not handle as quickly as a race bike, but still performs fairly well? If thats the case, the geometry charts aren't really that helpful because neither has the number for fork rake or trail. Rake and trail and headtube angle are the three most significant factors in how a bike handles, so assuming that the rake and trail are the same for both bikes, the HT angle on the ZX3 is slightly less which would make it handle slightly slower, but at 1/2 degree difference I would say the difference would be slight.

Still not the info needed. No saddle height or cycling inseam. No saddle to bar drop information or stem length.

The vertical size of the bike is really defined by the head tube length or better yet, the frame stack height.

A TT length with no seat tube angle does not define the frame reach.

The answer is still most likely the 44cm.

i declare thread resurrection. im trying to get a general idea of common seating setups.

what is your effective seat tube angle? you can do a mess of trigonometry, but for simplicity, this number is seat tube angle minus centimeters of setback. also, the style of your riding at that angle, whether it be touring, racing, or otherwise, would be helpful.

i do faster, longer riding at 74 and around towning at 72.
