Its a chain stay mounted chain device thingty – dead simple and I wondered if any one had used one and what they thought? crc brand x linky

Blimey, there’s a blast from the past!
Very popular back in the day along side DCD’s & purple bar ends.
All I can remember about them is they’re not the quietest of things.

Hi,

Yeah i used one for a little bit. Easy to set-up, i had no issue with noise, well made. The only problem you may have is the shape of your chain stay. Mine was on an On-one 456, and getting it set-up for chain alignment was a nightmare.

The ‘NOTE’ worries me?? 😯

I was thinking of getting something like this for my 1×6 cargo bike as there’s an awful lot of chain to get caught up in things if it does ever throw the chain from the front ring.

Anyone know how big a chainstay it’ll fit round?

I wouldn’t bother with it tbh. They used to cause more problems than they solved back in the 90s.
