It is ideal for 1x 10/11/12spd and Singlespeeds. Oval (elliptical) chainring does not compromise the work of clutch mechanism in rear derailleur(video at the bottom). It also does not require chain tensioner when using in singlespeed application. Riding out of saddle on the uphill will become more pleasant.

Ovality of the chainring is in range of 10-14% (dependent on size) and feels perfectly round when riding. These chainrings also help you to recover after knee injuries as pedaling becomes smoother and less exhausting. It is the most advanced oval chainring currently on the market.

Chain options

10, 11 or 12spd chain for geared bike or 6-9 spd one for SS (1/8" also fits). 

Chainguide needed?

No. But if you want one then chain guide should have 2 teeth more capacity than nominal oval ring size.
