I own a Beone road bike (59 cm) which I think is quite big for me. I am 181 cm tall with 83 cm inseam. I am going to sell it, aiming to buy Scott CR1 Team 2013. I mailed a store to ask which is the size that fits me best and their answer was the XL (58 cm). Comparing the geometry of my bike with Scott I find little difference as you can see.
The numbers reffer to BeOne 59 Scott 58 Scott 56 respectively
SEATTUBE 590, 580, 560
TOPTUBE 585, 575, 560
HEADTUBE 175, 196, 176
SEATTUBE ANGLE 73, 73.3, 73.5
HEADTUBE ANGLE 73.5, 73, 73
WHEELBASE 1000.5, 1001, 992
Currently, to bring the 59 frame to my needs I changed the original seatpost with one with no offset and switched the stem from 110 to 80 mm. The Scott (58cm) comes with 120 mm stem.
Don't you think I should go for the 56? I don't want to make the same mistake again.
