Designed to stop wheel slipping for Cross-Check's Semi Horizontal dropout.

Hurdy Gurdy is another nifty device that keeps a rear wheel from slipping forward in the dropout under pedal load. It's designed for our Cross-Check's semi-horizontal front-loading dropouts, and will also work on many other similar dropouts. Hurdy Gurdy is investment cast of stainless steel for durability and good looks, and shares many of Tuggnut's design features. Its two axle holes allow for a wide variety of fore/aft wheel positions, it will work with standard QRs, bolted axles, and nutted axles up to 10mm.

Protect your MWOD chainrings

• 58 BCD Bashguard for MWOD crank 
• Black alloy

Single chainring drive train setups are all the rage these days.

With the introduction of exceedingly wide range 10- and 11-speed cassettes, the need for two chainrings has become a thing of the past.

But when you only have one chainring, the only thing standing between you and a long walk back to the trailhead is you making sure you don't destroy your one chainring.

That's why we made a charing guard to fit our O.D. cranks. It is made of aluminum and will take the hit for your chainring.

It comes in 5 bolt, 94mm BCD.
