Many steel drop bars have the same diameter as an MTB bar and some people use a steel drop bar but switch out the brake lever clamps on regular drop bar brake levers for the smaller diameter ones needed for a steel drop bar. Those people often mount their MTB thumb shifters on the top of the steel drop bar.
