Japan of course is a mecca for bike part manufacture, Nitto, Shimano, various small frame shops and bicycle works from around Osaka which produce beautiful pieces like this bell.
This bell sounds like a Tibetan singing bowl or something, the resonance on it is astonishing. One ting and it rings for a good fifteen to twenty seconds before the sound dies away. It brings smiles rather than scowls on the towpath. So serene and peace inducing is its sound that inner calm explodes from within with every ‘ting’. A masterpiece of Japanese craftsmanship.
Available from Rivendell Bicycle Works in America for 8 USD. I recommend it most highly.
