Shimano go to great lengths to test their products extensively before adding them to the XTR range.
The Shimano XTR SM-CRM91 Chainring is designed to be run on a 1x11 platform and is compatible only with Sil-Tec chains and the race (M9000) and trail (M9020) XTR cranksets. Keeping that in mind, its' new XTR tooth profile on the SM-CRM91 reduces chain noise and drag to a minimum and also aims to make chain guides obsolete thanks to Shimano’s proprietary chain retention technology. The 'up-side' of all this means that with reduced likelihood of dropping a chain you’ll spend less time fixing first-world chain problems and more time dominating the trail.
