I have an aluminum hardtail frame that I want to put a disc mount on. A local machine shop said they could do the welding, but I need to find the tabs for the caliper. Anyone know of any place to get them?

I have another option you may want to consider...

I purchased the adapter from Specialized used for the FSR's to add a disc mount to a non-disc frame. It attaches to the brake boss, then bolts onto the dropout (I had to drill a hole, but that is pretty simple to do in the dropout). If you had a big enough dropout, you'd be able to do it as well. If you are interested, I'd sell the one I have, too, since I no longer have the FSR frame. You can email me at ljklassen(at)mts(dot)net - replace the words in parentheses with symbols, of course.

there's a product called "brake therapy" which is supposed to be excellent, works on the same principle, but attaches to the rear hub axle and has a torsion strut to the canti boss. It even works to discify trials frames, which is the holy grail of trials frame engineering, given the enormous braking pressures exerted on trials bikes.

Check out the above bolt on adapter from A2Z Components. These are around $60 and you can mail order them from www.discbrakeadapters.com

Basically it's two pieces of metal that sandwich your dropout plate. They will not fit the Breeze-in style dropouts, but will fit most flat dropouts. These are handy because they do not require mods to your hub, so it works with any exsiting wheel.

I actually ordered and installed one last week. Works great! The only drawback is having to take the skewer all the way out to remove the wheel. Not difficult, but time consuming.

Do you have a pic of your setup?

I've been curious about this adapter and was thinking about installing one on my Catamount.

Try Russ Denny

I went through the same thing a few months ago. I bought a 2001 Rocky Mountain DH TO frame expecting it to have disc tabs, but when it arrived it didn't. I contacted Russ Denny since he's local and ended up having him do the work. In the process he ordered the tabs -- I would send him an email and see if he can help. His web site is:

http://www.russdennybicycles.com/

His email address is listed there. Shoot him an email -- he's a great guy and I'm sure he would help you get those tabs or at least point you in the right direction.

As far as the adapters go, it really depends on your frame. With mine, they might have worked, but none of them fit well and gave me much confidence. Welding tabs on the frame cost more, but it's extremely solid and reliable. That would be my recommendation.

Good luck!
