What crankset to get?
Moderator: robbosmans
Hello my fellow weight weenies
I am currently running an ultegra 6800 110mm crankset with 52-36 chainrings and I am looking for a new crankset with the following perks:
-will definitely run Qxl rings in 52-36 option so the new crankset must be compatible with that.
-I am looking for a possible reduction of around 100 grams from my previous set up (this means that cranks+Qxl's must be lighter than ultegra cranks+regular
chainrings).
-looking for the cheapest option available since I am on a strict budget, unfortunately ( cheap is relative offcourse, the crankset must be good enough for high
level racing).
So, what are my options? (tried searching myself but failed, because guess who is a monkey and can't use the internets )

Used hidden-bolt Red, still the lightest option available and unchanged for 3 generations of Red (10s/11s/Etap) - for good reasons.

Like that idea since I am riding sram red etap already,but when you say unchanged for 3 generations of Red (10s/11s/Etap), is it surely the same? or are there any changes in space between the rings and stuff like that that might cause me problems with etap?
ok, so I won't probably shave off the desired weight, but ok, I am still within reach of my final bike weight goal so nevermind! now, I only need to know if any sram red crankset is good with etap or if I'll need a newer one...if not, perfect! also what is the deal with gxp and bb30? it confuses the hell out of me tbh!
If you're running etap already, presumably you have the exogram cranks mentioned above?
What with them being normal 5-arm cranks, you should be able to put q-rings straight on nae bother.

etap shifting I mean, crankset curently is an ultegra, as I wrote above!
Ok, asked around and found out that there wont be a shifting problem with any sram crankset beyond 2012....So are there any other cranksets worth considering? rotor 3d+ maybe? any other brands out there worth looking?
Only Clavicula is lighter than Sram RED IIRc. But then you have to be ok with the looks & the price.
If you are upgrading to a power meter and would consider a crank based one then now is probably the time to accomodate that aswell.
Sram red exograms are light but come with not so light/accurate power meter options. Exogram supports pedal based and left arm based meters.
Rotor cranks like non exogram red usually supports the more popular spider based pwm's.
Also not all pwm's play well with qxl rings.
If you don't plan on getting a crank based pwm then I say go sram red exogram. Bb30 is lighter but often unsupported. Your frame needs to be bb30/pf30. It's a short axle with larger diameter. New frames are wider so bb30 cranks are becoming obsolete. Felt/Specialized/S-works/Pinarello can still be had in bb30. You get around a 100gr weight reduction compared to other standards when you factor in bottom bracket and crank weight.

I just put on the new Rotor Aldhu with Q-spidering. The rings are 12.5% oval vs QXL's 16% so it's a halfway step from original Q, but it's much lighter than standard 3D+ cranks and the rings are extremely stiff. So far the front shifting has been perfect and they run silent.
I am looking at it as well, it peaked my interest! also I am not going to use qxl eventually, I thought the bike I had borrowed for a race had qxl's on but it had plain qrings, so plain qrings is the way I'll go, or the one's on aldhu if I get that, which also seem really nice!wingguy wrote: ↑Wed Apr 18, 2018 7:56 pm
