Serotta Build Questions (components)
 

hi all,

i have 2 (dumb) questions about my Serotta build.

the frame is a 2009 CDA with carbon rear stays.

I am using full DA, but not sure if i should use a short cage or a mid cage rear der.

Also, not sure what size band to get for my front der. 28.6? 31.8? 34.9?

thanks in advance for the help....

short cage for regular double
medium cage for compact double or triple.

for the band size, measure the seat tube diameter with callipers, failing that 2x right angle measures.
