Guys, cos I feel that I'm a little bit caught in the middle, I need some sensible advice, different point of view to help make my mind.
The problem lies in the choice of the crank for bbright system (cervelo r5).
This thread's title describes the conclusion I came to: Red GXP vs Rotor 3D+.
What I like and dislike:Red Like
potential of changing the appearance and shaving view g;
the match with the rest of the Red components (no big fuss);
cheaper than Rotor.Red dislike:
extra weight, compared to BB30 version;
24mm spindle, not native to bbright, not fully taking advantage of bbright;
necessity of using extra adapters.Rotor like:
bbright native, 30mm spindle, full utilisation of bbright system, no adapters;
the same weight as Red crank (gxp with adapters, chainrigs excluded);
some say "cervelo looking" crank (debatable);
look better (imo) with q rings, which I would like to give a try.Rotor dislike:
I can live with the graphics, but if I change my mind....;
some say "cervelo looking" crank
Some figures (compact):
Red: crank arms 415g, oryginal chainrings 157g, bb 85g, adapters 39-50g, total 707g.
Rotor: crank 475g, q rings 154g, bb 85g = 714g.
In this configuration Red is much cheaper £284 vs £421.
Situation changes when you go for lighter chainrings. At this point price difference comes to £30 ish.
What is the stiffness and performance difference between these cranks?
Compatibility q rings with Red...?
Now I'am on Red coupled with Record crank, standard bb 68mm. And I'm very happy.
