Advice for the correct size

by evroniano   May 30, 2013  

I'd like to purchase a new road bike, a battaglin s11 sora and I'd like to make sure I pick the right size for me.

I've taken all the measures requested by competitive cyclist fit calculator and this is the result

what do you think ?

here it is the geometry of the frame

Thank you very much for your help

I'd probably go with M, from the measurements I'm guessing you're somewhere in the 55-56 bike size range. Also if I couldn't find the right size, I'd rather go with a bike a bit too small rather than one bit too large.

It looks as though you have long legs for your height, so will need to ensure you don't end up with a top tube that's too long. I think if you go for Large you will end up having to get a short stem.

The most important measurement to get right is top tube - B, so around 540 in your 1st 2 fits, right between S and M
Seat tube can always be adjusted with seat post height
If you are 178 tall I'd go with M, esp as head tube D is pretty short on the S
I'd try some out with a similar top tube in a shop to check if poss to check reach
For the same as Eddy fit 2 you'd need a 90-100mm stem

That isn't my kind of bike, the head tube is too short Smile

Or to put it another way, the top tube is too long

it turns out the measures of B and C are inverted, as a result for the M the B is 535 mm while the C is 550 mm, for the L the B is 560 mm while the C is 575 mm
I've just spoken with battaglin customer service
