Bosch mid drive lock ring tool
Review by Peter L. on 16 Aug 2018 review stating Bosch mid drive lock ring tool
Shipped quickly and price was right, I was experiencing chain suck after putting on a new chain, to install a new front chain ring to solve the problem I needed this tool. Perfect fit, definitely a genuine Bosch tool.

A: Hello,
No, this tool is for Gen2 drive units that use the small chainrings.
The tool you need can be found here: scooteretti.com/products/bosch-gen-4-locknut-tool
This will work for Gen3 and Gen4 Drives.

A: The lock ring tool I purchased does not fit the bosch performance line motor. I had to purchase an after market lock ring tool as the bosch performance line motor requires a 42mm OD. and not a 50mm OD.
