Hi,
I have always raced on a standard but have recently switched to a compact SRM to keep my rides in control during the off-season. For the reason I need a set of LARGE compact rings to run for the spring/summer.

Right now I am thinking about going 52/38 maybe even 53/39, 110bcd & 11 speed. Stronglight CT2's are my top choice of course but given their hollowed out shape I am nervous they will become floppy at this size. I would rather not have to splurge 170usd on a set of praxis rings if I don't have to. Thoughts, comments and suggestions please!!!!!

Hi, the praxis rings are excellent, but expensive. You could try strong light and if floppy flog them off for almost what you paid and get the Praxis.

Cheers and good luck.

So you bought compact cranks only to then want to put 'standard' tooth chainrings on a 110 BCD? And now worried that the rings will be too flexy?

The logic of this escapes me.

This is what I don't understand. Is 50x11 really going to keep your power down significantly?

Edit: if you had no power meter before, then I think I get it.

I've been very impressed with my Praxis compact so I'd say them or perhaps a Rotor Aero set (for stiffness).

I use CT2's, and you know I just wouldn't recommend them at large sizes. Get something with more meat on them.

It sounds like Rotor Aero or praxis are the way to go. It's a shame the praxis are so expensive but I guess they are worth it.

Given the praxis rings are drop forged like DA rings yet cost a pair what the DA rings do each I wouldn't say they are expensive. :roll:

How is $170 expensive? They are bombproof and last. Shifting is perfect. A Dura Ace is twice that.

You could also go 52/38t with Specialites TA or KCNC makes the Blade in 53/39t which is stronger than the KCNC K3 Cobweb.
