I'm trying to compare the frame measurements of a cross bike i sat on today (a Scott CX comp 54cm) to my road bike (bianchi 928 carbon 53cm) I really just want to compare the top tube lengths and seat tube + standover heights.
bianchi (its the 928 carbon one)
scott cx comp
The bianchi pic doesnt seem to have a measurement from BB centre to toptube centre, but it has another measurement marked A1 but i'm not sure exactly what this is measureing 😳
If i use B1, BS and the angle G2, can i use this and some trig calculations (i'll have to look these up cant remember how to do it!) will i be able to work out the short side of the B1 BS triangle, and if i subtract this from AS i'll have the BB to top tube centre length??
Still wont give me the standover height though…
And i before anyone says just meausure it, i cant as the bikes not here at the moment 🙂
