Reddit reviews KMC 415 Master Link Single 1/2 x 3/16 / 3 Piece Black

Here's what I used when I assembled mine:

1. Socket set, metric, 8mm to 18mm with extension
   
2. Phillips-head and flathead screwdrivers
   
3. Drill with a 5mm or 1/4" drill bit
   
4. Needlenose pliers (slip-joint could work too; I used both, they're cheap at Dollar General)
   
5. Chain breaker for breaking the 415H chain (I used this one and needed a new master link too)
   
6. Large cable ties
   
7. Utility knife or snips
   
   If you need any recommendations for motorized bike accessories, let me know!
   
   EDIT: I just came back in from working on my bike, and I think something else you might find helpful is metric combination wrenches. I recommend this mechanic's tool kit, though I have some cheap Chinese TrueValue tools that work really well too.
