How about a 29t with a 94bcd crank? I think smallest you'll get without using the granny position...
There's a few that still come in that 94/58 bcd format. Depending on what crank you have you might even be able to change the spider. Check Middleburn or White Industries off the top of my head...birddog99 said:sounds good, what cranks have a 94mm bcd in the middle position?
