• Compatible with Bafang M615 BSHD only
• Curved-in shape to bring the chain to a more centred position. In other words, the chain is far less likely to drop off.
• We have chosen 44T instead of 42T for a better balance between torque and top speed.
• CNC Alloy 6061 Lighter and better looking
• Narrow and wide design to catch the chain better thus better chain retention for eMTB
• 19-20mm off set
• Is it a lekkie Bling Ring ? No, it is the same thing if not better.
