These values are directly from the spreadsheet Hope sent me:
Tech V2:
Includes Tech lever, post caliper, adaptor, braided hose, 203 floating rotor
514g (above with vented rotor 629g)
Tech M4:
Includes Tech lever, post caliper, adaptor, std. hose & small rotor (160 or 183mm)
466g
I am assuming the M4 has been weighed with the 183mm rotor as otherwise that does not make sence…
There is also weights for rotors:
Floating Rotor – 183 – 146g
Floating V2 Rotor – 183 – 180g
Floating V2 Rotor – 203 – 208g
Which means the V2 set with a 183mm rotor should weigh 486g vs. 466g for the M4
Clarity, I think 🙂
