Silent Sprockets

[HiFi]

Hello, well the rain stopped any plans I had for riding this weekend so while idly surfing I stumbled upon these:

Never heard of them before, anyone have them? Are they just a gimmick or do they work?
Cheers

Never heard of such Hifi, sounds a bit odd but you never know - all new tekknoggollyy I know nothing being tekknoNumpty

30 % noise reduction. Would it really be worth it. An old chain will always make more noise than a new one in good nic. Wouldn't mind seeing one in action though to see if it's smoother

Just adjust your chain right, grease it and fit louder pipes!

Hmm, interesting concept, but I, for one, wasn't aware that transmission noise was a problem looking for a solution! They do look nifty though, I'll give them that. I see they do them for a 'Busa so it sounds like one could be made to fit a rap. Are they made of ergal, or what? An ergal rear is on my wish list as my current rear is heavier than the OEM one and it seems like a good idea to try and keep unsprung weight down.

Never heard of ergal before but apparently it was used in the airframe of the Zero:
