We all know and love the new Bafang 8fun mid drive system. The biggest problem is they are over-geared! We have solved this problem with our custom 104 BCD Spiders designed for the Bafang BBS01 and BBS02 mid drives! This is an extremely high quality piece of hardware which we designed to be both lightweight and strong. This spider, with the right gearing, allows you to increase your torque by over 25% when using a smaller chain ring. The new 2019 edition is 35% stronger while still maintaining its lightweight profile. We have sold over 1000 of these without one problem! Our customers have ridden thousands of miles on these without any problems!
Don't fall for cheap imitations
- Custom 104 BCD Spider for Bafang Mid Drive (made in the USA!)
- 5 x Spacer Washer
*Requires 104 BCD chain ring of your choice and 4 x chain ring bolts. Using a good quality single speed chain ring (such as the raceface narrow/wide sprocket) will prevent any chain slippage and keep the chain from falling off! The last photo shows the chainline with a 10 speed rear cassette and 36T sprocket!
