Hi

I am in the market for some of after market road compact chainrings, and I wanted to know what my options were and what is decent / tested by you lot.

I need the following;

-110 compact
-5 bolt for use with Power2Max PM
-50/34

I would like;

-Light as possible
-Stiff and hard wearing, and up to proper hammer
-Rad

Price is not an issue.

I have done some basic checking and have seen the following;

PraxxisWorks
Extralite

Erm... and that is it.

Anything else out there at the moment I should be checking out?

I am running Dura Ace 9000.

+1, I'm using Praxis 52/36 on my power2max 3d+. Works and looks great, and shifting is indistinguishable from Shimano 6800 I have on another bike.

For good shifting, praxis. For acceptable shifting but very loghtweight, carbon-ti.

+1 for Praxis. isn't the lightest (mine 151,44g - standard) but shifting is top notch.
I have BOR rings (137,77g - std), shifting ok, but nothing as Praxis.
Maybe Praxis Classic model is a little lighter than Clover.

Edited after re-reading OP and noting the type of crankset.

Other options are TA. I think it's the hegoa model thats 110. Should come in a little over 120g for the pair.

Right, so I have been using Praxisworks Levatime compact rings since late June.

I have set my Dura Ace Di2 up perfectly...

-The down shift is fine, and smooth.
-The chain rolls alright on the rings and isn't too noisy.

But...

-Flex; the big ring flexes when sprinting.
-Upshifting is SHOCKINGLY bad, to the point where I have to pedal super soft and carefully when shifting up. Every single time, the chain slips across the top of the teeth, and take time to engage. When it engages, it is held at an angle, then makes a snapping noise when it finally comes off, like the terrifying early stages of chain suck. Also, every upshift is different, with the slipping happening more or less, each time, and occassionally the chain completely falling over the outer edge of the big chainring altogether (and scratching my SiSL2 crank arm like bastard).

Totally unimpressed. I have seen other people complaining about this upshifting too, and I have definitely got everything dialled in perfectly. I don't run old chains, and replace often, and installed a new chain when I installed the rings the first time too.

Seriously, they are crap.

So, looking for other rings to try now...

It's a shame you've had problems as it's the Complete opposite for me, couldn't fault my praxis rings at all with my DI2, the shifting was sublime up and down. Unfortunately for nothing but to loose weight and to look good I changed to Fibre Lyte and now can not get the chain to engage on the up shift, it's so annoying i will be changing them for Extralite rings and most probable back to Praxis. !!
