This process helps greatly reduce chain noise and improves

Machined from strong 7075 T6 aluminum, the world-renowned Sugino Zen is stiffer than any other track chainring, exceptionally round, straight and smooth, and used by Olympic and World Championship medalists.

These mighty chainrings also feature the SSGN super smooth tooth profile, which means the tooth valleys are rounder and the side tooth profile is smoother than standard Sugino 75 rings. This process helps greatly reduce chain noise and improves ring/chain engagement and wear.

Silver 44t-55t are NJS stamped.

Logo color variation info

The newest production run arriving from Sugino Japan has a grey & white logo on both silver and black chainrings, as pictured.

We do still have some stock showing the older logo colorway (black & red on silver chainrings and white & red on black) but as that variation sells and is replaced with new stock, there is no guarantee which one you will receive.

Please understand that we cannot accomodate requests for certain logo versions.

Easy Claims Process
It is not a long complicated process to file and resolve a claim. Be warned--sometimes they will want you to send back the defective or damaged product, even if it's not worth the shipping ---they pay. Overall worth the investment though.

Asurion you made the return process simple
Working with Asurion was an easy process. My previously covered milk frother stopped working, and they fully refunded it with no questions asked. All I had to do was ship the broken item back to them and they sent me a gift card. To cover the initial cost, no questions asked. The refund process was a very simple and painless.
