that is a very interesting concept... is it safe?BMC TM01 - FCN 0

Ummmmmm.... is that really a good idea? Fizzycysts?

Well, it'll work...
You'd be overworking the chain though, no?
In any case, it's not something I'd trust - if the chain snapped, you'd have zero kind of braking. Except perhaps your face.0 -
Interesting, but it will only apply the brake to the rear wheel - nice for long skids.Cycling weakly0

right up until the brake pads get lubricated with all the oil from the chain.. or your chain snaps.0 -
Pretty sure that would still make the bike illegal in the UK. You need two independent brakes, so a fixie with a front brake is fine. A fixie with that contraption is reliant on the chain not braking, otherwise you're stopping with the soles of your shoes.0

Hmmmm, advantage = power of a disc brake without the weight issues. And on a fixed it sort of duplicates the pedal braking action.
However, on a fixed, does the weight saving mean anything useful? Also, as someone who covers a lot of miles on a disc braked bike, I can say that whilst the effectiveness is excellent, the sqeaks and grinding noises you get from discs when anything isn't absolutely right is a bit annoying. I'd have thought there'd be a lot more crap waiting to get into the calipers from the chainwheel teeth than you get on the wheels.Faster than a tent.......0 -

Surely when braking, as the gearing will be working in reverse, the brake will be proportionally less effective than the same caliper fitted to a conventional wheel based disc. <waits for physics correction from Greg66>
A pretty high chance of either it being so weedy that you'll have to put your foot down, or, if your weight goes forward, leaving half your tyre on the tarmac.
+1 on the chain oil getting under the caliper as well.1985 Mercian King of Mercia - work in progress (Hah! Who am I kidding?)

And crank flex - these will have to be solid cranks and chainring! Just half a mm flex and you'll rub the brake every pedal stroke.0

You're quite right, I missed that.
(Bigger discs = greater stopping power; the gear ratios effectively work to step down the size of the disc).0 -

It runs without lube, dry chain.0

What would Thora Hurd do?0 -
Hmm....
Thickness of chainring much greater than traditional disc.
Teeth on chainring means braking surface is far deeper into the diameter of the chainring than 'real' disc.
Entertaining concept, but suspect photoshoppery or bored-engineer mock-up.0 -

Running chains dry is not a new thing - I know of a few (and of some 'experts'!) who prefer it!0

With dry lube though, surely, rather than no lube...?0 -
No, none! They say it stops contaminants been driven into the chain. It will work - though I have never tried it so can't comment on how long lol.0

silly if you ask me, if the wheel locks up your legs are still gonna be trying to move.... or if you pull the brake hard then let go you will shoot up in the air...
I bet someone tries this with a SS bike :twisted:

thats just silly, as numerous people have said, your chain snapping = death0

Presumably a dry chain can never be used in any kind of damp or even humid conditions? But then in dry dry conditions you'd have dust issues. Can't see it working tbh.
I think this is a nifty idea but a flawed reality. Like so many things.0
