Shifting is decent with the 1091R chain - it overshifts a little occasionally with the praxis rings. The stronglights had a tendency to drop on the outside if I slammed the shift hard up with the 1091R. (the CT2s were fine with the KMC X10SL - occasional overshifting, but no drops) butt feel says the praxis rings are stiffer, but may be the $170 placebo effect.
X10SL chain is smoother front shifting on both the praxis and stringlight rings than the 1091R chain.
Didn't remember to weigh the new rings unfortunately. I'm running a red yaw front derailleur and 3rd gen s-works cranks.
On the Quarq site's ring calibration table the Praxis 110mm 50/34 rings are marked "not recommended as the slope difference between the rings exceeds 2%." Bummer.
r_mutt wrote:yes, 110 BCD is not recommended, but 130 BCD is. i called Quarq and they recommend the standard rather than the clover chainring style for a Quarq Powermeter. i've been looking for a substitute for the Stronglight CT2 rings because i've had 3 pairs of 53/39, and i've bent the 2 of the 3 big rings. the last one lasting less than 1000 miles before i noticed a wave. i'm no gorilla either- max power those rings have seen is just over 1,300 Watts and i weight 155-160.
Similar power output and weight, probably ~200 miles on a 110bcd 52T Stronglight CT2 and a noticeable bend in it now.
Anyone else experience this?
front: 104.0 grams
rear: 35.4 grams
total: 139.4 grams
Not installed yet -- presently recovering from injury and not riding.
Heavier than I expected: was hoping for 133 or so. Someone good with a drill could get the front down a decent amount.
Can anyone tell me if the following Stronglights will fit on my 3D24 crank? (I have now 110 BCD Qrings)
https://www.bike-components.de/en/Stron ... is-p24706/
1. TA Specialties ( never again ) ,
2. Stronglight CT2 ( nice, very nice - but as mentioned limit on big ring has to be set up precisely and tiny bit closer than it seems to- then works perfect ) ,
3. Rotor ( so so, nothing really to complain, but also nothing to be happy , I would say "Tiagra" level of shifting, softest from all )
and finally ( because of Campa crank ) MIche Super 11.
Designed for 2009-2011 cranks ( 2 part bolts ) surprisingly ( 4me) fits PERFECTLY to Rotor 3d24 110BCD crank. I didn't check weight , but after about 1500km on it ( Campa Chorus & Sram Force 22 ) I'm more than happy. Shifting is faster & crispier than on previous chainrings.
Stiffest from all mentioned above even on extremely low cadence ( like 40-50 ) under heavy load not even small sign of bend, color is kind of brown-ish ( a la Campagnolo ) , regular Rotor bolts hold it without issues .
What you can not like : shifts are crisp , read almost "brutal" - Shimano softness lovers will be disappointed. But it has benefits : shifts always, regardless conditions- in deep snow, mud, covered by sand, ice , after 80km on very dusty gravel… without any hesitation or delays.
Chainrings has plenty of pins and special ramps - I believe it cause so nice work . Another plus is availability : 34,36,38 & 42,44,46,48 . Reasonably priced, so won't damage even "budget" builds.
I use dit with Chorus, 1190 & 1170 chain. No noticeable difference .
Hope it helps.
I can be wrong, and have plenty of examples for that
