It's interesting to see the solutions that already exist. Most seem hydraulic. I wonder if we could cable actuate some of this. Maybe even get @kazlx to fabricate

I assumed he would still be using a rear shifter. that's a lot of right hand activity (nttawwt)

Give us more info on your bike setup now, and how'd you would like it to be.

I don't know why he couldn't thumb brake with the right hand as well as use the index finger for regular braking. Could probably even use a regular lever mounted a little farther inboard and rotated backwards.

You no google?

ATVs use cable actuated thumb levers. This is cheap enough to test the idea. No idea about bar diameter compatability.

There's a guy who rides on Cypress with a prosthetic arm. He's got both brakes (hydros) on one side of his bars. I can't seem to find the article about that was on pinkbike a while back....

not the same person but similar...

old post on singletrackworld

if a rear shifter isn't in the mix I'd think the standard lever + thumb brake would be the cat's pjs.

cable actuated coaster brake for the bad hand?

 

[kazlx]

Open to help out, but would probably be way easier to modify something existing rather than make new. First step is decide what type of setup would work for you.

 

[Nick]

it just dawned on me that some of the new cyclocross hydraulic discs are cable actuated. I'd imagine their similar to the original rockshox cable.hydro calipers. Maybe misuse one of those, with a trigger style device for le thumb?

I think a device that is controlled by butt clenching would be right up his alley.

This is 110% very many accurate yes. Butt clench = brakes engaged
Somebody rep the hell out of this man and give him a Dr. Pepper.

take the bulb and tube from a blood pressure testing cuff. Connect it to a brake, cornhole it.

two diff guys...one on n'shore, other here in nc, as noted above.

I wonder if the nsmb guy upgrades the shock on his prosthetic? Is he rocking an x2 or a ccdba now?

Seems like it would be possible to design and fabricate a cam mechanism (for cable disc) that would allow you to actuate both brakes with one lever and vary the amount of force between the two. So basically you could adjust the cam to change the amount of force applied to each brake. Of course modulation wouldn't be independently controllable.

 

[johnbryanpeters]

If any of you have their shit together enough when riding to independently modulate front and rear brakes when riding, my hat's off to you. I run a larger rotor in front than in back to roughly balance things out when the same force is applied to both levers.

If I were chasing this I'd go for a single lever solution.

Really, even with a motorbike background? I definitely modulate front and rear brakes independently.

The lack of independent modulation is what worries me about that kind of setup. I've never studied my old habits that hard, but my gut says I don't always uniformly apply pressure. There were situations where I'd favor my front over my rear and vice versa. I'm also not planning on riding the same gnar I did before. It still seems there's an elegant way to have one sided control with independent modulation and the thumb seems like a good answer.

...ferrule thingy and a dongle...

make sure you put on gloves(even on the gimp hand) before touching someone elses though...
