Product Description

The Bling Ring built for 10–12 speed drivetrains

Modern 12-speed chains are narrower than older chains, and they ride best on a ring designed for them. The 42T PRO is Lekkie's premium BBSHD chainring for exactly that. It has a refined tooth profile that picks up the chain smoothly, even on builds where the chain line isn't perfect, and it runs with Shimano 12-speed, SRAM Eagle and KMC chains.

Like the 40T rings, the PRO has an external chain guide ring. It adds another layer of chain retention and keeps your pant leg out of the chain.

PRO or classic 42T?

  • Choose the PRO if you run a 10, 11 or 12-speed drivetrain and want maximum offset plus the built-in guide.
  • Choose the classic 42T Bling Ring if you run a lower-speed drivetrain (8–9 speed). Its tooth profile gives better retention with wider chains.

What's in the box

  • 1x Bling Ring PRO 42T HD
  • 1x 2mm Bling Ring spacer HD

Fitment note

The PRO has more offset than other Bling Rings, which is great for chain line but means it sits closer to the frame. On wider chainstays or fat-tire frames you may need the included spacer, or extra BBSHD spacers, for clearance.
