KCNC K5 Rectangular Road RingsThey call them "rectangular" chainrings, but they are an extreme a symetric ring!! They are certainly not round!! Designed to reduce the effect of the "dead spot" as the crank arms come round top dead centre (12 and 6 o'clock). They can increase power, they can increase efficiency, they can make you pedal smoother! KCNC use what they call an ovality ratio of 1. 225 on the K5 pattern rings, with a bi radial symmetry offset by 88. 3 degrees. 110bcd 39T

Came undamaged great quality put it up on a shelf next to my steelbook version of season 1 glad I got it. This show is so great. Owning a great quality version of it physically I'm so happy about. I should note I don't plan on taking out of the plastic shrink wrap it comes in. These in my opinion are great collectables so not opening either season. If I want to watch Ill just watch it again on netflix.
