What size Bike?(8 posts)

What size Bike?NEW ROADIE
Feb 5, 2003 12:03 AM
I'm new to road biking and I want to buy a road bike. I am 6'3''. What size bike should I buy?
Any help would be greatly appreciated. Thank you.

P.S. I have an opportunity to get the bike that I want MUCH cheaper but only in the 56 inch frame. Should I do that what would be the negatives in buying a bike that size for me which is obviously too small.

Don´t buy it! Don´t! :) A 56 would be too SMALL! I´m not even 6´2 (about 187 cm) and I would NEVER consider a size 56.

By the way, it´s probably centimeters, not inches.

Good site to start:

Without knowing your inseam etc, I´d probably guess you´d need at least a 60 cm frame (center to top). Go to a good bike shop, get yourself fitted. Ask your bike partners etc.

To give you an idea of how small a 56 is I am just over 5'7 and ride a 54 (granted a 54 that probably runs a little small).
The fact that it's WAY to small should be enough!(nm)merckx56

Definately don't do the 56...especially if you are aware that it is significantly too small.

I normally ride a 56 (6'0") and went with a 58 for my last frame.
When I looked at the difference in the numbers, I figured the 2.5 cm (top tube difference) would be pretty minor.
But all the bikes measurements are affected.
Just adjusting the seatpost and stem lenght doesn't take into account headset height (couldn't get mine low enough), etc.

And this bike was technically not TOO big for me, just a little bit big.

I'd keep looking if I were you....

I would go to your local bike shop and get measured. Besides getting the right size, you'll also be starting, what should be, a valuable relationship with a known professional. You'll need advice more often as a beginner. I too just started and have found my LBS to be the best source. This board being the second.

Watch out for LBS who mostly recommend bikes for racer boyseflayer

Make sure you know whether aerodynamic is more important to you than comfort. Many shops only know what the market is pushing them toward, not what will be comfortable for you.

Good luck

I'm 5'11", have an 86cm pubic bone height, and I ride a 60cm Riv Rambouillet. This is the new gold standard in my stable. I like the big bike feel with the bars at least even with the saddle.
