Installing both V-brakes and Disc on same wheel??

I am gonna install both v and disc on both front and rear of my Epic. I want them to both work off the same lever. This way I'll have the best of both worlds. I will post pics probably tomorrow. Has anyone else sone this yet?

Ive heard about it being done, but whats the point? surely discs are enough, maybe even just the V's, save your money there is zero point.

I agree. I have also heard of someone running dual disc up front on a custom hub.

I'm assuming you're going to use an inline doubler?

Or are you going to run two brake lever setups like what this person did with a MTB tandem?
No, thats been done and would be to easy, I have Hyd. Discs anyway!

Hydros? Then why waste your time and money on getting rim brakes.

Go with that setup. Then while going fast downhill, jam on the front brakes (disk & vbrake)... and break your collarbone.

Cheath - Can I ask why you want to have a set of v-brakes ASWELL as a set of Hydro disks?

Its just a plain stupid idea putting both v-brakes and discs on.

It will also be very very hard to set up the brakes right so they work together dude. Chances are you will have it setup so that they don't engage at same time...... And why waste a set of brakes!!!

Can your tyres handle that much braking force?
Tandems use dual braking systems (usually on the rear) to provide a drag brake on long descents. They also have twice the weight and a long wheelbase.
Solo bike just dont need/can't use that much braking force.

It's a ******** idea. It would be extremely difficult to get the brakes adjusted so that they worked together.

You say you want the best of both worlds.. well, how exactly are you going to get that? V-brakes are cheap, simple and light, but require a heavier rim that must be very true. Disc brakes are more complicated, heavier, and expensive, but allow a light rim that doesn't have to be perfectly true.

Combine them, and what do you get?

An extra heavy setup with extra maintenance headaches, questionable reliability (whatever rube goldberg scheme you come up with to activate both mechanisms), which probably won't work any better than V's or discs alone, due to the difficulty in setting them up to work together (most likely, one of the mechanisms will do most of the work).


If you want to be able to stop in an emergency when both your back and front brakes fail, try getting a parachute pack.


Double front discs make some sense, if you're a 350lb downhiller who routinely burns up 8" discs into white hot dust. If you're not, don't be stupid.

I have a more productive suggestion though.. set up your bike as a fixed gear - that way, if the brakes fail, you can slow down with your legs. Oh, and let me know when you take it on the trail.. i want to watch...

I was thinking along the same lines that they won't work together. You'll be getting one to engage but not the other. They will only work together after the v-brakes are level with the amount of pressure needed to use the disks, assuming that the v-brakes engage alone first. As it wears out, it should even itself to a point where both will engage. Beyond that point, then you'll have to keep adjusting the v-brakes to stronger then the disks so the process will repeat itself.

Basically, I think it isn't worth it. You'd still be burning up brakes.

just purely from and engineering standpoint, I think it could be done w/ a set of those magura hydrolic rim brakes. If you could find a way to increase the size of the master cylinder on the lever, you might be able to put soome sort of splitter on the hydraulic line and then you'd have a rim+disc arrangement. might be interesting to see someone do it. I say that you go ahead and give it a shot.

I think it would be very hard to get the setup right because you'll probably have to deal with different pad contact rates. Also, once things start to wear, it'll get real interesting.

not to mention there would be two forces braking on your rim at the same time, one in the center and one at the rim. Wouldn't there be possibility of twisting/untruing your wheel every time you brake?

I think it'd be a cool experiment. Diffucult, expensive, inefficient, overall waste of money, Yes. But still pretty cool to say that it was successfully done. Then go back to the disc brakes and sell the vbrakes on eBay.

I am thinking about putting a flat bar and a low rise bar on my bike with a custom stem. I will build the stem out to carbon fiber to save weight. Then I will install 2 seat posts to be used with 2 seats. This is so I can have the perfect riding position for climbing and decending.
