Wolf Tooth Direct Mount Drop-Stop Chainring Chainrings

With so many direct mount chainring styles on the market, it can be hard to find the right fitment and size, but never fear! Wolf Tooth make the choice easy with a selection of top quality chainring options.Who’s this item for: Riders in need of an upgrade or replacement direct mount chainring.

Chain retention technology: 

Drop-Stop technology is Wolf Tooth’s patented wide/narrow chainring design. The wide side of the tooth has maximum contact on the drive side which spreads the load and improves chainring life. The narrow side allows clearance for mud and debris which reduces friction. Alternating wide/narrow tooth pattern prevents chain derailment.

The new Shimano 12-speed chain rings use a different technology than Drop-Stop as the Shimano 12 speed chains are not compatible with the standard Drop-Stop tooth profile. The HG+ chain interacts with the chainring differently than a traditional narrow/wide design so Wolf Tooth took the time to understand how the HG+ system worked before they produced their new Shimano 12-speed HG+ compatible chainrings. 

Chainring Fitment: Cannondale Hollowgram – FSA Modular Direct Mount

Chain Compatibility: 

• For 1×9, 1×10, 1×11 and 1×12 drivetrains (including SRAM Eagle).
• Compatible with all 10-, 11-, and 12-speed chains except Shimano 12-speed chains. 
• 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). 

Crankset Compatibility: 

This direct mount chainring will replace your existing spider/chainring on Road and CX Cannondale Hollowgram SI & SISL cranks. These are NOT compatible with Cannondale mountain bike cranksets because the chainline will be too far off from optimal.

• Shimano 12-speed chains require the use of the Shimano 12-speed specific chainrings.
• If using a 9-speed drivetrain use a 10-speed chain. It fits tighter for better chain retention.

Crankset Compatibility:

• These direct mount chainrings will replace your existing chainring and spider or replace the direct mount ring on SRAM cranksets including the DUB cranks. The ring is attached via 3 bolts on the back side of the spider near the spindle. 
• Note that the SRAM 12spd Red and Force AXS use a different 8 bolt mounting interface that is not compatible with these chainrings.

Chainline: There are 3 offsets (6mm, 3mm and 0mm):

• Standard: 47mm chainline, 6mm offset for cyclocross and road cranks
• Standard: 49mm chainline, 6mm offset for GXP and long spindle BB30 
• Boost: 52mm chainline, 3mm offset
• BB30: 49mm chainline, 0mm offset for BB30 short spindle cranks
• Fat Bikes: If your fat bike has a 170/177 rear hub spacing, use the Standard 6mm offset
• If you have a BB30 crankset (30mm diameter Aluminum Spindle) the measurement in the spindle picture will determine whether it is a long or short spindle.
