    BBSHD chainrings. Why nothing between 30T and 42T

    I use a 104 BCD adapter for my BBS02 so I can choose any of the raceface chainrings in the 30T to 38T range. How come there is not the same selection for the BBSHD? It appears that the smallest raceface chainring I can find for the 130 BCD adapter is 38T. Why nothing smaller? (Except of course the Mighty Mini) Also, is there some technical reason nobody makes a 104 BCD adapter for the BBSHD?

      I just ordered a 36T myself. Looks quite nice in the photos. You don't happen to have the offset measurement for that by any chance do you? I didn't see that info on the precis alps website. Thanks again.

      Thanks callyman. Much appreciated. Since I've posted this I've found out that Lekkie is making a 36T too. I'm interested in precialps's 34T myself.

      Think I can expect the paypal transaction to convert euros to us dollars for me?

          I've just bought the BA130 from California Ebikes with a 40T RaceFace cog.

          https://california-ebike.com/product...nring-adapter/

          My BBS02 came with a 44T standard so I wanted a bit of a drop but not too much as I still ride mainly roads.
          It seems to pull a bit better, I've not tried for a top speed yet!

            I just found out about this ebike specific drivetrain from SRAM. Allows use of 11-48 cassette. This, and an Eclipse chainring is probably the answer to my dreams. (Not cheap however)
            At SRAM we are passionate about cycling. We ride our bikes to work and around town. We ride our bikes in the peloton, on the trails and down the mountains. It's this passion and participation that leads to many of the innovations seen in our products. We hope you enjoy them as much as we do.
