We used BB 36mm for our shooter mechanism last year. Zero problems.

This year, we used a BB 125:1 for our wrist movement with a further 2:1 chain reduction. This is a more demanding app and its out there, getting hit and being used constantly. So far, it has survived 2 regionals, no problems (knock on wood!)

We are also using the 56mm tranny to move the main arm. This time with 2 sets of chains to reduce shock and add reduction, and the original carrier plate. Again, no problems so far.

BB offers a nice lightweight, inexpensive solution that is easy to implement, and reliable if treated for what it is, namely a lightweight inexpensive solution. Asking too much of these little guys will get you chipped gears, which we did during testing. Treat them well and they work out just fine.

Our experience with BB has been good. We will use them again.
