Brand and era of the drive train Match , You have to get the reach , saddle to bars distance to match
maybe the stem makes the DT not the same as your road bike ,
retape the bars and move the levers up the curve a Bit..
Yea Brifter are long in the body to have space for the clockworks inside.. then you needa Short ramp Bar to go with them.
fatten up the bars with another layer of padded tape and you may not feel like you have to hold onto the lever hoods the whole time..
