so the d-fuse post on my defy is 7mm only, i guess i could get a Berk, but is there anyway of swapping out parts of the clamp so i can use what i already have or a regular carbon railed saddle?

if not, whats the best options? currently on a Fizik Antares 00

If you have the d-fuse with the side bolt clamp head (found on the carbon bikes) you can swap out the head parts. I did this on my 2015 defy advanced pro to install S work carbon rail toupe saddle.

The parts are black or silver denoting metallic rail or carbon rail compatible, your giant dealer can supply

Is 7mm the standard for most saddles ?

If you have the d-fuse with the side bolt clamp head

i do,

i guess i get the guts off Giant?

@iainc … 7mm round for metal rails, 7×9 or 7×10 for carbon … generally

^^^ thanks for that, often wondered !

its the silver clamp parts you want. here is what I had for my toupe carbon saddle on my Defy last year

make sure to liberally coat the clamp parts in carbon assembly paste and set the bolt with a torque wrench as the design has a tendency to slip if you hit a pothole which can cause a “clunk” and change of saddle angle!

is the pink ribbon for added speed ? 🙂

its the silver clamp parts you want

ordered them yesterday, cheers

@iainc

you should see the handlebar tassles 😉
