Can Someone Give Me Direction

It's the frame builder, not the material. Rodriguez makes a really comfortable frame.

It's a combination of many things, actually.
Aluminum 'in general' gives a harsher ride than steel.
And of course no frame is comfortable if it doesn't fit right.

Serious1- it might be good for you to consider exactly what biking can do for you.
Yes you can lose weight if you increase your activity level overall and don't increase your calorie intake along with it. But by riding a bike frequently you may also gain muscle (muscle is heavier than fat) and you'll increase heart/lung health, improve circulation, plus many other benefits- mental, emotional, and physical. Many overweight women start biking and when they don't lose a bunch of weight right away they get discouraged and stop. Actually, what is happening is that they are losing some fat and gaining some muscle and their body shape is starting change. I don't weigh a whole lot less than when I started biking but I sure am shaped differently! Woo-HOOOO!

Biking offers so much more than just the weight thing- it will give you a whole FITTER and HEALTHIER life. Dropping excess weight will likely follow naturally as you slowly improve your whole lifestyle.
All this can start with just a few little bike rides each week- they can be as short as just around the block a few times or like 1 mile down the road and then 1 mile back. Try to enjoy your riding and keep it fun and do-able....that way you won't hate it and stop....you'll love it and want to do it more!
Good for you wanting to make healthy changes!
