Tbf I’ve got a great knog d-lock

I bought a commuter with some Tektro disc brakes on them ready to swap out for bb5s straight away

Turns out they are very good, done 1000+ km still great

Anyway they have an integrated bell on the lever and it’s a decent volume and in a very ergonomic position

I was thinking about getting some of those piezo speakers that they put in birthday cards to play this as a bike bell:

Bing bing, bong bong, bing bing bing….

Any links? I was interested in the design, but not in the price.

Though to reduce handlebar clutter, I now have one of these on my MTB http://www.planetx.co.uk/i/q/BEPXHSS/planet-x-headset-spacer-bell
