SHOP CHAIN LUBE

Looking for a 1X chainring for your Shimano XT, SLX or Deore crankset with the proven chain retention of our Drop-Stop® chainrings? Wolf Tooth has what you need in the form of a beautifully machined asymmetrical 96 mm BCD that provides the ideal 1X chainline of 49mm.

NOTE: The 28T and 26T sizes are available mount to the inner 64 BCD mounting position on these cranksets.

Compatibility

  • These rings fit on the Shimano XT M8000, SLX M7000, Deore M6000, or  FC M5100 1x or 2x cranksets 
  • Not compatible with Deore triple (3x) cranksets
  • If using a 9-speed drivetrain use a 10-speed chain (shifts and works well on a 9-speed drivetrain and fits the ring tighter for better chain retention).
  • Provide a great chainline on most Boost bikes.  See this explanation for details.
  • Drop-Stop A models will reduce the chainline (inward towards the frame) from the Shimano specified chainline for the crankset: 26T-28T = -3mm, 30T-34T = -2mm, and 36T-38T = -1mm
  • Drop-Stop ST models will have the same chainline as the Shimano specified chainline
  • 10mm bolts are optimized for mounting this ring

Recommendations

  • If you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur. Without these precautions, you may experience chaindrops and/or chainsuck.

Details

Details


Tooth shape is nearly identical to Drop-Stop A, but has narrower teeth. Valley between teeth is deeper to accommodate larger rollers on Flattop chain. Outside faces of narrow and wide teeth touch chain to guide alignment.


Drop-Stop B Chainrings navigate_next

The original Drop-Stop tooth profile. The wide teeth are wider than Drop-Stop B. Outside faces of narrow and wide teeth guide chain alignment.


Drop-Stop A Chainrings navigate_next

Narrower teeth than Drop-Stop A. Wide teeth use Symmetric Trapezoidal (ST) profile to match extended inner edge on chain to create alignment (outside faces of wide teeth do not touch). Interaction of narrow teeth and chain are similar to Drop-Stop A and B.

*We are in the process of migrating most Drop-Stop A to Drop-Stop B to make them compatible with  SRAM Road and Transmission (T-type) Flattop chains.
