ProX Ultralight Steel Rear Sprocket  

The ProX ultralight steel rear sprockets now come in a new and revised design. The new design is slightly lighter as current ProX ultralight design and can be up to 35% lighter than other regular steel sprocket.  These sprockets are all manufactured from premium quality high strength steel and offer superior durability, even under the most extreme riding circumstances. Using the ProX ultralight steel sprockets is a great solution as they easily offer 2-3 times the lifespan of an aluminum sprocket. 

The center holes are precision cut on CNC machines using tight tolerances. The mounting holes are all countersunk and cleaned for perfect fit. Teeth are cut with a special procedure called "Diamond Cut" which keeps tolerances of overal diameter and wobble under 0.2 mm. to guarantee super smooth running. As a finishing touch the ProX ultralight steel sprockets come with black color coating for extra protection and great looks.                                                                                                          

The sprockets are machined in an ultralightweight but strong design that brings a perfect balance between strength, performance and durability.
