Roland V-Drums trigger cone replacement

In this video I replace the trigger cone of a PD-125 drum. The kit (a TD-20K) is 16 years old and has lost sensitivity over the years, only striking the center of the drum actually triggers the unit. After replacement the mesh drums honestly feel like new. The new cone is an OEM part from Roland, part number 01909478 SENSOR CUSHION

I would definitely not remove the old cone this way. By pulling on it you risk cracking the ceramic layer. It's much better to saw through it with floss or string, maybe drenched in mineral spirits. That helps dissolve the adhesive. Then gently rib off the remaining adhesive residue with mineral spirits or acetone, I suppose.

I hadn't considered that, sounds like an safer/easier method than pulling on it. Thanks for the pointer, I'll give it a try next time. I will say though that I've replaced 4 cones via pulling with positive results (and these components are quite old), so the ceramic layer must be fairly sturdy.

Man. I had to recone a PD105 today in an emergency. I couldn’t get double sided tape to stick to the cone I had laying around, so I used Velcro, lol. Works fine!

The piezo is a 20cent part. It's not that dramatic if it cracks. And he smashed it already for 18 years ... This thing is stronger than you think.
