Hello,
I am about to purchase a specialized tricross comp.
Dimensions in bare feet 8 inches apart
Height 174cm
Height to Sternum Notch – 140.5
Inseam Height allowing for saddle compression -79.5cm
Arm length ribcage to centre of palm – 63.5cm
Weight – 178.5lbs
My question is concerned with the correct bicycle frame size. I have visited 2 specialized dealers ……One of them stating that I should purchase a size 54…….wjile the other states that I should purchase a size 52.
Which of them is correct…..This is a very big purchase for me and I need to get it right!
Can you please advise?
Many Thanks,
Jerry

I’m 5′9″ but have a 30″ inseam. Sooo, long on top and short on bottom. Sizing charts say I should be on a 51 or 52 cm bike, but that doesn’t make sense to me. I think a 54 would be better in the long run with a longer top tube. Your thoughts…also, what length stem??

WIll this suit me size wise??? Thanks to anyone who can help..

http://www.prodigalchild.net/Bicycle6.htmTry the above frame size chart from Dave Moulton, I think it is really good! For instance, I have a 32″ inseam, so should theoretically use a 54cm bike. But I’m 5′11″ tall (short legs, long torso), so 54cm is too small for me. By interpolating between the two, I found that a 56cm frame should be about right, and guess what…..it was!
