The Cobweb chainrings I have on my Ultralight are no longer tickling my fancy (too flexy). The sure do look cool and tick the weightweenie check box but the performance is lacking in my eye, therefore I am looking to change things up. I have a few options in my mind of what to do:

current setup: FSA SL-K Carbon 386EVO 110BCD Crank with KCNC K3 Cobweb 53/39 Chainrings.

Option 1: SL-K Crank with Rotor 52/36 110CD Rings
Option 2: SL-K Crank with Rotor 52/FSA 38 110BCD Rings (anyone have an opinion on cross pollinating rings?)
Option 3: SL-K Crank with FSA 52/38 110BCD Rings (Cheapest)
Option 4: SL-K Crank with Praxis 52/36 110BCD Rings
Option 5: Rotor 3D-F Crank with Rotor 53/39 130BCD Rings
Option 6: Rotor 3D-F Crank with Praxis 53/39 130BCD Rings
Option 7: other suggestions to fit BB386EVO Frame

There are zero hills where I live so the bigger rings are my preference. The 36 tooth would be merely useless for me as I usually ride the 39x12/13 on my easy days when I ride alone, so I would prefer to have a 38/39 tooth small ring.

Not into upping the ante to the 3D+ as i cant justify the extra $150 for 30ish grams

I'd go for the 53x39 praxis option. Very stiff, forged, and still decently light. If you have the cash, they're a good investment.

given what your preferences are, Option 6, although I voted for option 7 for your consideration: Lightning crank, Praxis 53/39; Lightning was making BB386 before the moniker was invented, no adapter needed. Very stiff crank and rings, crisp shifting, yet nice and light.

52/38 and the like on 110 BCD will be flexy. I suggest going 130, but that probably requires a new crank.

I am currently using a Rotor 3D+ with Praxis rings, it is a great combination. Previous to the Praxis rings I was using the standard Non-Q Rotor rings, changing to the Praxis rings offered a noticeable increase in stiffness.

Incidentally, I have a brand new in box 3DF crankset for sale minus the rings, it is 110BCD and 175mm - viewtopic.php?f=5&t=122978

My 3D+ and Praxis setup is shown below.

Stoked you guys like our rings so much...great to see.
A couple emails from this thread so I thought I'd chime in.
Our primary reason for forging is that it allows us to create really complex and subtle tooth shapes that allow the chain to move so well. The added benefit of our forging process is that it creates a really hard & tough surface so it makes for a durable tooth. So it's really a two-fold reason for forging.

Drop us an email if any more questions at info@praxis-works.com...and thanks for the support!
