If i compare C60 in 50S size headtube which is 145mm and Road Logic in 53 is 140mm which is not big difference. I guess ill have 5 mm more spacers on Ritchey, which is ok.
I guess ur Road Logic was 53 size? In 55 size headtube length is: 160mm, so i guess if u went that size it will be ok comparing to ur Colnago.
Can u please tell me more about Ritchey way of riding? Sprinting efforts? Climbing? Is it reactiv? How was handling? Sport car handling or more sluggish? If u can compare it with ur C59 i'll be very thankfull.. And i guess u had 53 cm Road Logic?
Yes, my Road Logic was a 53. I chose that size because the effective TT on the 55 was, I felt, too long for me. If Ritchey made a 53cms frame with the HT from the 55cms it would be perfect for me.
Ritchey way of riding...? I just rode it.. lots!
Sprinting, climbing etc were all great. You have nothing to worry about with its performance, handling or anything. In comparison to my C59's (I had 2 of those) it was slightly less agile in the steering, but absolutely not sluggish. With carbon everything these days, I think people have all-but-forgotten steel... The Ritchey isn't some 1980's / 1990's, slack, slow-handling, blunderbuss.. it's a modern, sharp, well engineered bike that you can ride very hard, flat out, and it'll put a smile on your face.
It's different to the way a C59 or C60 rides, but that's the point isn't it? I wanted something different - a different look, different feel, different characteristics.. but still a rewarding bike to ride.
PS - no facing required.
Analyzing Road Logic geometry and im a bit counfused trying to determine number of spacers i'll have compared to my bikes i ride now..
Road Logic: Head Tube 140mm
C60: Head Tube mm 145 mm
So based on the head tube Ritchey i'll need 5mm more spacers under the stam
But based on stack:
Road Logic: 549mm
C60: 547 mm
So based on stack on Road Logic i'll need 2 mm less spacers under the stem..
So which number to use to get number of spacers determination?
Head tube Length comparation or Stack Comparation?
Or, better.. To have the same vertical position on Road Logic, will i have more or less spacers compared to C60, and by how many?
