Hello,

Someone I know rides a belt + 380% Enviolo + mid-drive Brose-powered cargo trike, and moved to a hilly place where a single chainring doesn't provide enough range to ride uphill without spinning too much on the flat.

It's unusual on a mid-drive, but FSA happens to make a dual BCD 104/64 spider. Before ordering, I was wondering if anyone here had tried it and could provide some feedback. It looks like a 46/30T setup would be ideal.

And since it's a one-time job, is there a cheaper alternative to getting a spider puller + cap kit along with a lock ring tool?

Thank you.
