I am new to road bike and having difficulties to decide best bike size for me. (I already watch and read tons but I could not find any valuable info)
I am 179 cm height and inseam of 85cm.
Bike is a Cannondale SuperSix Evo. Based on Cannnondale size chart I should go 56. (Size 54 - 170cm to 178cm / Size 56 - 178cm to 182cm). I tried both but I have no experience. Store staff said it is better to go 56. But I felt better on the 54.
Is there a rule of thumb on this situation when you are just between two different sizes? Should I go 54 or 56? (I will do a bike fit later to fine tune)
Thanks for any inputs.
