This is an optional Exotek XRAY XB2 Direct Spur Hub. This spur mount eliminates the slipper clutch, and is a great option for stock class racing with your XB2. At a mere 3.4 grams, it is lighter for increased acceleration and a cooler running motor, and is compatible with both Exotek and Kimbrough spur gears for increased gear ratio options! Plus, it is easy to switch back to the slipper setup when conditions call for it. 

Includes 3x5mm hardware for Kimbrough spurs. For Exotek spurs use 3x6mm alloy or titanium screws (not included) for even greater weight savings.

NOTE: Not compatible with Avid, Schelle or similar aftermarket top shafts.

Compatible Spur Gears:

  • Kimbrough
    • KIM301 66 tooth
    • KIM150 69 tooth
    • KIM143 72 tooth
    • KIM161 73 tooth
    • KIM162 74 tooth
  • Exotek
    • EXO1543 66 tooth
    • EXO1544 69 tooth
    • EXO1590 72 tooth
    • EXO1545 75 tooth
