Nice idea, but it's heavier than my alligator lightweight (72g) and hardly lighter than my A2Z aluminium spider (with a fuller braking surface than your's and 89g), needs more work to make any sense I'm afraid. Also you've offset the braking part from the correct location, although probably OK with PM mounts.
Impoverished weight weenie wanna-be!

There is epoxy resin (industrial strength) as well as the bolts holding the steel outer ring .
It's 160mm size .
Don't forget the carbon spider decreases the amount of flex compared to those steel narrow rotors (1.8mm diameter all the way through) .
In response to mattr removing the top sections of the bolts does nothing in terms of tensile strength . They are a permanent fix (with the resin) so to answer your question I'm a good engineer !!!

What?
I mean the clamping face between the bolt, disc and hub. The disc is held in place by friction between hub/disc and disc/bolt. Removing 1/3rd of the friction surface is going to give you odd loadings in the bolt, reducing the end load. You'd have been better off having 3 correctly installed and loaded bolts, than 6 half cocked bolts with out of spec loadings.

Ah I see what you mean . Well glad you are insulting me as it just cements the lack of character you have. anyway I took the idea from Kettle Cycles . The bolt heads being wide enough support the rotor pretty well . As long as the bolts are torqued correctly there is no failure . Again you are commenting with no experience of using this rotor . No movement from the spider and no cracks or anything from the carbon .

Quaxar have a 160mm rotor for 67g, KCNC is 72g and Alligator 76g.... all £15-20. Even Hope X2 is lighter and offers significantly improved all weather braking compared to the other lighter, cheap rotors. What is the intended advantage of this custom rotor?
Also interested to know more about the background as the tinkering and thought going in to stuff has to be commended. Plumbers call themselves heating "engineers"
