Are these only for bikes that currently have discs or can they be used to retrofit non-disc bikes? If

Your hub(s) must be disc ready, if not you will have to replace the wheels or have your old rims rebuilt onto new hubs. Some bikes have only the rear hub disc ready as disc brakes on the rear only is popular. You may also have the threaded mounts for the brake mechanism built on your frame but if not you can get a bracket.

More than likely the bike will need to already have discs on it. For a bike to be disc comparable it must have wheels that have disc hubs and a frame that has the proper mounts. Sometimes frames middle to upper end have the proper mounts but you would need to replace your wheels. Do a quick search for disc brake mounts and you'll see what you need to have, as well as a search for disc hub pictures and you will see how the disc mounts to the hub with the 5 bolt system.

Sorry, just saw a comment below... Frame and fork one thing but your wheels must have hubs disc ready

I had forks and frame with disc mounts already however I'm pretty certain you can get adapters. One thing for sure, These are terrific - I looked I to these a good bit before buying and would clearly recommend... Very easy to install - look for model on YouTube and it'll be a snap! Best of all, you'll be in stopping heaven - really, you'll never want caliper or 'v' brakes again. Good luck

The brakes fit hubs that are part of the wheel. If you have a non disc bike, you would also need new wheels with compatible hubs.

No you will need adapters. There is a model that will work it s special "disc brake" model.

The discs have steel grippers on the backside, that are designed to be used on steel rims. Alloy rims would likely get scraped up pretty bad, if you put these on them. They might stay on, but eventually the material removed on the alloy would reduce the tension of the disc grippers. Less tension means a greater chance of losing them. Steel rims are designed for the use of wheel covers, and I'm certain most alloys are not.

I wish I knew the answer for you sir...all I can say is they sure worked perfect for my mongoose mountain bike. I just had to get a longer brake cable for my front brake. Much easier on my back. :)

Hello, i would think so as it's the wheel it's going on, you'll have to modify something.. I've seen disk brakes on regular bike frames Nashbar is a big supplier and would be able to answer your questions directly. The brakes are great for the price I have them on a specialized big hit comp replacing some very expensive Hayes hydraulics that are not worth the maintenance, the levers are sub par but will work.Hope this helpsTw

No. I haven't been able to find ones that can be retro fitted for this bike. Looks like you have to change the entire axle.

I do not know the particulars of your bike, but most bikes have the same mounting holes. This topeak is for diskbrakes. If you do not have disk brakes, you have to order the other style. There are some good videos on youtube showing the mounting

What model bike are you mounting these on? Are you upgrading an existing disk caliper or moving from a rim caliper to disk brakes?

Yes, if your bike has disc brakes and a cassette hub (as opposed to a freewheel hub). If you don't know what you have, take the bike to a bike mechanic - he/she will not charge you anything to tell you what you need.

I agree with SPC. While I don't have disc brakes on any of my bikes, I don't see why it wouldn't work. There are two "pincers" to the rear frame and there seems to be some limited top/bottom - forward/rear adjustment to the frame anchor points.

My set of these came with adapters that enable you to put them on either of the two types of mounts. I put them on my Mongoose 29 from Walmart. They work a lot better than the standard Promax that came on the bike. One thing that might be a negative is that on my bike the wheels kind of warp to the side of the disc when the brake/brakes are applied.

They are universal. They are drilled with long hole slots so they fit tons of bikes. They fit my Busa perfectly and fit my wife's CBR also. You shouldn't have any problems.

I bought this brake to replace the cheap broken brake on a bike that I purchased from walmart in2012. The new avid brake bolted right on and works great.im not an expert but I think that disc brake mounts are fairly standardized . Good luck

They would work, but most mountain bikes use disk brakes. These are more appropriate for ordinary street use.

I have disc brakes on my bike, no problem there. I do not know about a rear rack as my bike will not allow for one. Hope that helps! It's a great product!

There is no "easy" way to make a non-disc brake bicycle, that does not already have the necessary bosses to mount them, into one that is capable of running discs. Not to say it cannot be done. Anything is possible with enough fabrication skills. It'd be way easier to find a used mtb with discs and refit the brakes with these.

In order for you to convert <easily> to disc brakes you need to have wheel, frame and fork compatibility. From the left side of your bike look at the outside edge of your wheel hub, the lower front fork and the the rear seat stay above the axle. You should see, if compatible, six small threaded holes in the wheel hub <for disc mounting>, two threaded standoffs on the fork and rear seat stay <for calipers>. The absence of either will preclude compatibility and be an indication of what is required. Your existing brake levers, if mechanical wire pull, should be compatible.
