MTB Road Bike Ceramic Bearing CNC Pulley Rear Derailleur 12/14T Jockeys Wheel(14T Red)

• *MTB Road Bike Ceramic Bearing CNC Pulley Rear Derailleur 12/14T Jockeys Wheel
• *Light design, 12T only 12.8g, 14T only 14g
• *The wide and narrow tooth profile fits more closely and reduces the gap, which can shorten the speed change response time and improve the speed change performance to a certain extent.
• *Deepen the tooth marks to reduce the chain loss, optimize the inclined tooth shape, and synchronize with the chain transmission direction, so that the chain entry and chain release are smooth
• *Made of aluminum alloy material, for and practical to use

Feature: *MTB Road Bike Ceramic Bearing CNC Pulley Rear Derailleur 12/14T Jockeys Wheel *light design, 12T only 12.8g, 14T only 14g *Si3N4 ceramic bearings are not easily deformed by for FORCE, and are resistant to cold and temperature, wear and resistance, high transmission efficiency, and more labor-saving riding *Si3N4 ceramic bearings Design,When rotating, the centrifugal effect of the outer ring can be reduced by 40%, and the service life is greatly extended *The wide and narrow tooth profile fits more closely and reduces the gap, which can shorten the speed change response time and improve the speed change performance to a certain extent. *Deepen the tooth marks to reduce the chain loss, optimize the inclined tooth shape, and synchronize with the chain transmission direction, so that the chain entry and chain release are smooth *Made of high aluminum alloy material, for and practical to use Specification: *Material: Aluminum alloy + ceramic *Opt Color: Black,Red, Gold(As Pictures Show) *Opt Type: 12T/14T *Size: 50*50mm (12T)/57*57mm(14T) *Weight: About 12.8g (12T)/ 14g (14T) *Applicable screw aperture: 4/5/6mm *Applicable transmission system: 8/9/10/11 speed *Compatible: for MTB,Road Bike .
