Specialized Ruby vs. BMC Road Racer?

[TigerMom]

A 44cm Ruby would definitely be too small for you. I am 5ft 1in short legs with long torso and I totally felt scrunched on the 44cm Ruby. I am currently on a 48cm Amira....which you might want to try out also while you are in the Specialized shop.

For me, the Ruby seemed to have a more awkward handling than the Amira....but everyone rides differently. As for the "uprightness" of the Ruby, you can always lower the stem and flip the stem also if you want a more race position. The Ruby is better than the Amira for someone with a short torso because the top tube is a little shorter.

As for the "twitchiness" factor of the BMC road bike. I road my friend's BMC bike (which is a 52 cm and was way too big for me) while standing up so I can't give a fair comparison.... but, the BMC seemed twitchier because the stiffness of the bike translated into more of my power into the bike speed.

So, maybe you've heard that the BMC racers are more twitchy because they are stiff and responsive, which translates more pedal power into speed??

As always, choosing a bike is a personal preference/personal budget. If you have back pain issues, maybe the Ruby would be best for you?

Oops, I misread your post about the Ruby rather than the BMC being twitchy. The Ruby did not seem twitchy to me but did seem to have a more ackward handling for me than the Amira. Maybe because of my long torso, the Amira had better handling for my body type than the Ruby.
