Firstly don't buy a new one. The dtx caliper isn't that great. Yes its better than the single pot standard. But it's not better than my four pot caliper that i paid £30 for in perfect working condition.
If it were me. I'd buy the best brake possible. A nice four pot radial monster and install that.
Yeah that brake will fit sure. But it might not sit on the disc properly or reach it enough. From standard. If you mre prepared to make up some brackets then like insaid. Grab yourself a monster if a brake.
