Trek 4300 disc brake conversion

Hi everyone, new here to the forums and am looking for a little guidance. My bike is a 2001-2002 Trek 4300 and I'm looking to add disc brakes. I know my fork has disc mounts, but does the rear of my frame have mounts too? If it does, would a disc adapter for IS mount frames work, or is there some other adapter I can use? Or am I S.O.L and can't run a rear disk with this frame?

Thanks in advance for the help.

Nick

Those holes in the picture are not caliper mounts.

As for how you'd go about adding a mount, I don't know. Chances are you may not be able to.

Yikes, I really hope there's a way to mount a rear caliper. It doesn't make sense to me to have disc mounts on the fork but not the frame. Thanks for the reply, though.

Would something like this work? http://www.jensonusa.com/store/produ...+6+Rotors.aspx

All suspension forks have disc mounts. On the older 4300's they did not have a rear disc mount. The newer 4300's come with disc mounts and cantilever mounts. Adding a mount could be problematic. Better to buy a different frame and move your parts over.

Brake Therapy and AtoZ Components make adapters for frames without rear disc caliper mounts. Don't know if either will work with your frame. You'll have to do some research.

Nick, you're in luck.

A2Z makes an adaptor that mounts a 51mm I.S. to a non-disc frame.

You have inspired me, Ed. I looked over the Brake Therapy adapter again and I think I'm going to make my own for the Trek HT. I found an outfit that sells 1/2" 6061 radius and tie rods, 7 - 16", in " increments and 5/16" aluminum Heim ends for reasonable. I'll just need to fab the hub-to-Hayes-adapter piece out of some billet and bolt it all together with stainless hardware. New winter project.

I'm looking forward to seeing that.

Your dropout will accept a Trek adapter to disc brake. I think the part# was 210648.

There is a new sticky, thanks to Ed, that covers this and many other conversions:

Retrofitting disc brakes to a non-disc frame...

It will become you one-stop source for the subject as it gets fleshed out.

I forgot about these. Good call. (I think they were going for somewhere around $40 on ebay a yr or two ago)

Totally forgot about that little jibber.

It's all good. Ed just created the thread yesterday, I added to it and stuck it last night (I lucked onto that Trek adapter when I was creating my post). Kudos again to Ed for taking the initiative.

Yeah, that's the CF Treks made between '05 and '08. During that time, they were using sub-par fibers...

I feel...helpful.
I don't like it.

You are all jerks and disc brakes are for wannabe's and V-Brakes live forever!
