Is this a commercial product? Any idea what brand, etc?

Dear John,

When I looked a while back, I never found any commercial version.
Nothing this time, either.

But you might risk $3.99 for the how-to guide.

The $3.99 guide:

Chalo Colina might have some useful tips about making the things.
Basically, you hang a piece of elegantly shaped but sturdy metal from
a handy nut on a clamp-on derailleur.

A commercial version would be nice.

Cheers,

Carl Fogel

I used to use them on tandems with a big drop from the middle to the
small ring.

Deda Dog Fang, 3rd Eye, and N'Gear Jump Stop are the three commercial
chain watchers I'm familiar with. I think the ones you are looking at
on Cycling News are custom made by the team mechanic.

I have that on one bike, but it won't fit on another.

First photo is a Jump Stop, available at any competent LBS, as are Third
Eye chain watchers. Both work well, under $20. Jump Stop is more
adjustable and hence often easier to fit.

Second photo seems likely to be a mechanic-fabricated guide or at least
I've never seen such available as a product.

Thats not a N'Gear Jump Stop. Picture has the bolt head protruding,
Jump Stop has the bolt head sunk into the plastic. Jump Stop also has
the metal guide come around from the back of the seattube.

Russel, you're right.
Uncannily similar, a Jump Stop analogue?

Dear Brian,

Yes, there are several commercial round-seat-tube chain-watchers--I
use one.

But I think that John is looking for the kind that hang off a front
derailleur or use a different clamp to work on non-round seat-tubes.

Cheers,
