A 32:16 on a 29″ wheel will be equivalent to 32:14.35T on a 26″ wheeled bike
Obviouslya 14.35T sprocket doesn’t exist, but the third smallest on a 11-32T casette is a 14T, the third smallest on an 11-34T casette is a 15T. So in between.
It basically going to be 1.1154 times as hard to ride in the same gear. It maybe that thats too high for the terrain you ride with whatever level of fitness you may have
A 32:16T on a 26″ wheeled bike is equivalent to a 32:17.85T on a 29″ wheeled bike. So the closest is a 32:18T setup (assuming still using a 32T front ring?) which is slightly easier, but not by much. The extra wheel weight will probably more than make up for the slightly easier gearing anyway
