Product Description

Low gearing without sacrificing chain line on BBS01/BBS02

For years the 42T was the smallest ring that kept a proper chain line on a BBS02. The 40T package changed that. Lekkie designed a slimmer drive cover that frees up space on the side of the motor, letting a 40T ring sit with even more offset than the 42T. You get easier climbing and a clean chain line on a derailleur bike.

The 40T ring has 2mm more offset than the 42T for builds that need it. If you'd rather run the standard 9mm offset, just fit the included spacer. It also has an external chain guide ring for extra chain retention and to keep your pant leg clean.

What's in the box

  • 40T Bling Ring (CNC 7075 T6 aluminum, anodized black)
  • Lekkie BBS01/BBS02 drive cover in your choice of red or black
  • 2mm Bling Ring spacer

Important: a 40T ring must run with the Lekkie drive cover, which is why this is sold as a package. It won't fit with the stock Bafang cover.

The Lekkie drive cover also adds a grease port and replaces the stock plastic cover with tougher aluminum. Finish the install with a Lekkie Onenut.
