CHAIN GUIDES & TENSIONERS

MKS CA-NJS 6mm C/Tension pr

MKS MX-10 8mm C/Tension Single

The 104 BCD bashring can be added to the crankset to protect a 104 or 64 BCD chainring.

- Properly sized to fit 104 or 64 BCD chainring
- Two sizes for ultimate protection: smaller 26-30t (132 mm diameter) and mid-sized 32t-34t (148 mm diameter).

Compatibility

These are for use with 104 BCD chainrings or 64 BCD chainrings on 104 BCD cranksets
These are compatible with all triple 104 BCD cranksets and mount in the “big ring” position
They are compatible with double cranksets that have flat outfacing mounting tabs, like XTR M980. However, many 2x specific cranks, like Shimano XT M785, have a profiled outer surface on the mounting tab so our bashring cannot be mounted on that non-flat surface.
These work great with the 104 BCD Elliptical 32t ring. They will work with the 34t as well, but at the max diameter a few teeth will extend just beyond the bashring.

Chainring bolt requirements for this bashring
104 x 30t - 10mm bolts are required for use with the bashring.
Other 104 BCD sizes - you will need 8mm bolts (stock size that comes on 3x cranksets holding the middle and big rings on). Wolf Tooth does not make these.
When using with the 64 BCD you will need 6mm bolts to mount the bashring. Note: Orient the head of the bolt to the inside to provide clearance for the chain (bolts will go in backwards).

If you are a 1X CX, gravel or road rider and can't afford to drop a chain, the Wolf Tooth GnarWolf® braze-on chainguide is for you. Designed specifically around 1x wide/narrow chainrings the GnarWolf will keep your chain glued to your chainring in the roughest and muddiest of conditions. No other CX chainguide is as rigid or as easy to adjust as the GnarWolf.

LOW SWEEP for 34-52T chainrings.

The new LoneWolf Aero Chainguide prevents dropped chains on road, gravel, and CX bikes with 1x drivetrains. This chainguide has been tested and developed with Team Jumbo-Visma, has been trusted in road cycling’s biggest races, and ridden to victory in the 2023 Giro d'Italia. LoneWolf Aero Chainguide was also ridden to victory through truly epic conditions at Unbound Gravel 2023.
We think of this little chainguide as 30g of insurance for races where a dropped chain could cost you a shot at the podium. The LoneWolf Aero Chainguide is similar to our existing GnarWolf, and combines a low profile head that only covers the top and inboard side of the chain with our GuideLock quick adjustment system. This eliminates the need for shims and gives you security in a light, easy to use, and aerodynamically optimized chainguide solution.

• Compatible with bikes that have a braze-on front derailleur mount
• Only for use with 1x drivetrains
• Works with round or oval chainrings
• Three base sweep options for chainring sizes ranging from roughly 38T-62T based on frame; Low sweep for smaller chainrings in that range will be most popular
• Head has 8mm of adjustment for chainline via our GuideLock quick adjustment system
