LevaTime® performance and proprietary forging process give the fastest shifts and longest lifetime of any chainring on the planet. Compatible with Shimano (Except the new Ultra 6800/DA9000 cranks with their new custom asymmetrical BCD). Sram and Campagnolo (Except on Campagnolo cranks with their proprietary Campagnolo BCD/Design, you would need to use third party cranks). These Buzz Rings also work with eTap and the Sram Yaw front deraileur.

Oren Got these to replace similar worn out chainrings after some 20K KM. So that is what to expect.
Mr Graham Best price on the internet at the time, top quality chainring, easy to fit and fast delivery.
Mr Ebbage Bought to replace a damaged Praxis Zayante outer chainring, as Praxis don't do singles. Best price around and delivered quickly. Very impressed, seem to be lighter than the one it replaces and easily fitted - direct replacement for a 48T. Runs nice and smooth 👍
Rich Drinkwater Cracking set of chainrings, I don't know if you would class them as an upgrade to stock SRAM Force rings but a great quality replacement. Good shifting and easy to fit. and now running these on both my road my road bikes that originally had SRAM Force chainrings. One note of caution is that you don't get any bolts with them so you need to use a little ingenuity in regards to the hidden bolt! Don't let that put you off as these are significantly cheaper than the alternative SRAM product!
John V A vast improvement over my worn out rotor chainrings. The shifting is smooth, quick and quiet.
Mr arana the praxis 50x34 chainrings have made my bike just like new again, silent shifting creates confident pedaling and they were very simple to change out myself, no need to remove the crank arms, very simple
Dr Knox Great set of high quality chain rings by Praxis. Easy to change out, and a great price from Merlin. This 50/34 set was for my Praxis Alba crank set, but its fits pretty much any 5 arm road crank set.
Juan Perfect fit and easy to install with no problems. I have about 600 miles on them now and working great with no noticeable problems. Hopefully they will last longer than my last chainring set that only lasted 3 years.
Ed Easy to fit, shifting is just as good as ever. Arrived quickly too
Andy B Very well made, light and easy to fit. Only gripe is the fixed selection of rings, would like to be able to choose. Excellent service from Merlin Cycles at a difficult time.
Mr Lee 가볍고 튼튼합니다
Cameron Great product, high quality, drop in replacement for my old Specialized 110 BCD chainring.
Mr Van Til Works great on my S-Works Power Cranks.
Reynald Praxis works Buzz chainrings works great as described. I can now climb to any hills that I might encounter. It works perfectly on 5 arm standard crankset. It shifts smoothly and looks strong and reliable rings. What a great a great setup! Thanks Praxis works...!
altofiend Changed my setup from 50/34 to 50/36 - much better for my gearing "sweet spot" vis a vis the terrain in which I usually ride. Very happy!
