Our direct mount chainrings for SRAM cranksets replace your existing spider and chainring with one clean looking, lightweight, and stiff piece of machined billet. They are available in 3 different offsets: standard 6mm offset, Boost 3mm offset, and BB30 short spindle/Superboost 0mm offset. This chainring has a 3mm offset to suit Boost drivelines.


These direct mount chainrings will replace your existing chainring and spider or replace the direct mount ring on SRAM cranksets, including DUB cranks. The ring is attached via 3 bolts on the back side of the spider near the spindle. 




CHOOSE YOUR OFFSET



  • Standard Road/CX/Gravel: 6mm offset for cyclocross and road crank applications with 47mm chainline

  • Standard MTB: 6mm offset for non-Boost mountain bikes, GXP and long spindle BB30 cranks for 49mm chainline

  • Boost: 3mm offset for 52mm chainline

  • BB30: 0mm offset for BB30 short spindle cranks for 49mm chainline

  • Fat bikes: If your fat bike has a 170/177 rear hub spacing, use the standard 6mm offset

  • Praxis Works Road/CX cranks use the 6mm offset. Praxis Works mountain cranks use the 3mm offset for their DM-A and 0mm offset for their DM-B chainrings.



DROP-STOP TECHNOLOGY


Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile delivers ultimate chain retention and mud shedding ability. Drop-Stop B is compatible with all chains except Shimano HG+ and Campagnolo 13-speed chains.



RECOMMENDATIONS



  • We recommend the use of a clutch style rear derailleur for the best chain security.

  • We recommend using a T25 L-Wrench or similar for removal and installation of the bolts. An L-wrench works best, since the crank spindle may contact a socket adapter and prevent it from engaging properly.

  • Use the same 3 bolts to attach the Wolf Tooth ring or we carry replacement bolts

  • For a longer lasting and more durable option, check out the CAMO System that offers stainless steel chainrings.

Cheap and unstable
Size: 4 Panel, Color: Black, Size: 4 Panel, Color: Black
Although this has nothing to do with the product, it arrived a day later than previously stated. Making me have to create a makeshift room divider the day it was actually needed. When the product arrived it arrived in a box that showed no evidence of damage. Once opened, divider was found inside a plastic cover. Great protector for dust or scratching. The divider was fully assembled so there was nothing for me to do but remove it from packaging and use it where needed. After further inspection the divider was not only cheap and flimsy looking it was absolutely unstable. It would wobble and appears to have been assembled in a rush making some panels crooked. I noted significant damage to the bottom portion of some of the panels both front and back. It does not feel like an item worth the price. The color is as advertised and the product had no smell. The sizing was accurate.

It really covers our privacy area.
Color: Off White, Size: 8 Panels, Color: Off White, Size: 8 Panels
This privacy screen really works! It is the exact size that we needed (8 panel) the white color brightens the deck and compliments the trim of our house.The weight is minimal and was easily put up by two people.As for the sturdiness, the screen is made for outdoors, so I am hoping it will stand up to rain and some wind.
