Derailleur works exactly as designed. No more chain drops like I was having with my 105 rd. Using it with a 11-36 cassette.

Spot on - smoother - quieter - and the clutch of clutch derailers. All bikes should have a clutch to reduce chain slap. Ride changing. Highly recommend for going up 30+ teeth.

Slapped it on my Niner BSB9RDO gravel bike. No more chain slap even on some rough hilly roads. Great product.
