MUC-OFF eBike Drivetrain Tool



If you own an eBike then you’ll know that cleaning and lubing your chain is a tricky business, as the crank doesn’t spin backwards like a regular bike unless it’s flipped upside down. But this can scratch components, or if you use an Allen key in your crank bolt it can get stuck in the bolt, or worse, damage your precious cranks!

Our new eBike precision machined drivetrain tool contains three different sized tool bits, which snap into place with a magnetized connection, all wrapped up in a durable CNC machined 6061 aluminium body. It fits straight onto your chain ring, so you can spin your crank backwards, and the protective silicone sleeve prevents any crank damage.

It comes supplied with a handy lanyard and carabiner clip, so you can keep the tool on hand for when your drivetrain needs some lovin’!

Directions for use:

  1. Unscrew the top cap then remove the tool bit holder from inside the body.
  2. Select the appropriate tool bit for your crank (5mm, 6mm Hex, T30 Hex) then place the tool bit holder back inside and re-screw the top cap on.
  3. Place the selected tool bit into the end of the tool. You will feel it magnetically snap into place.
  4. Place the tool bit into place on your crank bolt, ensuring it is in straight and central.
  5. Slowly backpedal until the crank buts up against the silicone sleeve on the body of the tool.
  6. Rotate the crank backwards whilst holding the pedal to carry out your cleaning and lubricating regime.
  7. When removing the drivetrain tool from the chain bolt you may need to pedal forward slightly.
  8. Carefully remove tool and store tool bit back inside tool bit holder

NB: Periodically spray a protectant such as HCB-1, MO-94 or Bike Protect onto the end and magnet to ensure there is zero corrosion
