Praxis Rings

Anyone have any experience with these?
Quiet?

They definitely don't sing or shout but other than that they are pretty much the best chainrings I've ever used (that incl Wickwerks too). I won't use anythingn else unless it's stock Campy or Dura Ace that came with the cranks. Once they are worn out, I replace with praxis.

[HillDancer]

Yes, quiet.

[carpediemracing]

I never thought of chainrings as "quiet" or not. The chainrings I've had are all quiet when new and get noisier as they wear. Record, Chorus, Cannondale SI (mind is blank on manufacturer… FSA?), and Praxis.

Currently running Praxis on two cranks, one has a 53x39, the other just the 53. I didn't bother with the 39 and am using a tandem inner chainring instead. On a Cannondale SI crankset with BB30 so the BB is not totally silent.

I use them for cross and love them. I don't know that I would replace 9000 or 7900 Dura Ace road rings for them, but for anything else, they are the best.

Note that they are designed for very aggressive shifting -- they shift fast and very definitively. You may need to readjust your front derailleur slightly because it won't need as much shifting action to move the chain. They are very tolerant of chains and of contamination of the chain and they will shift strongly in cross-shifting situations, more so even than current Dura Ace road rings.

They have a great set of cosmetic adapters for using the rings on 7950 cranksets. These adapters cover the ugly gap when using any ring other than a 7900-series with those cranks. Expensive but worth it, and because they brace the large ring half the way up its front face, they increase the stiffness over just using traditional chainring bolts.

Best...Chainrings...Ever

[r_mutt]

it's quite if you compare them to SRAM.

for whatever reason, I am not having the same experience as everyone else with them. perhaps it's an issue with my Quarq. i find it really slow to change from the 39 to the 53. sometimes it even hesitates before grabbing. the first set was even worse but these were replaced (thanks excellent customer service) and the problem was more subdued, but still exists. i'm just living with it for now. i can't wait to get back on Campagnolo rings.

I have been using some 39/53s for a while now. They are not bad. I don't think they shift as well as the new Red Yaw chainrings but they are nearly as good.

[civdic]

I used them on a couple of cranksets with mixed results. I had them on a THM M3 crankset and they didn't work well. Could have been the crank and chain line but they never shifted well. I also had them as replacement rings on my DA 7900. They weren't bad but nothing like the original DA rings.

[bigman]

Thanks for the responses - think I will give them a try.

[WickedWheels]

They are very very good. They make a great upgrade for SRAM/FSA/Vision people. I wouldn't pick them over the hollow Shimano rings, like Dura-Ace 7900 or Ultegra 6700 series, but they are worth the money.

What is sad is that they forgot the big C in their development. Good news is that 110 can be tweaked to work with C.

What's the tweak/trick to getting the 110 rings to work on campy cranks?

[Dromen]

Was ready to write off my SRAM groups til i changed out rings. They highly suggest using Shimano or KMC chains. NO NO to SRAM chains.

just swap out the shifters and dérailleurs and your nearly there!

:bike:

[ultraman6970]

The hidden bolt is off set, just dremel that hole in the chainring a little bit , since is the hidden one nobody will notice anyways.

I don't think anyone recommends using SRAM chains... Other than SRAM.

How do they work with Di2?

How do they work with Di2?

No reason for them not to work every bit as well. I have them on a Di2 bike and they're faultless.

[oldpotatoe]

How do they work with Di2?

They will work although the hollow shimano CRs were designed specifically with Di2 in mind.

[Charles M]

Di works just as well with Praxis rings... Di works pretty well with lots of rings actually.

Are those EE cranks still a dead project at this time?
