I was looking at the cycle therapy adapter, but the site hasnt been updated in 4 years. Woodman also makes an ok looking one. What I want to know is, what is the best adapter for a hardtail to run discs? What are the weights and costs of the systems? Should I just run a disc up front and a V in the back? Any input would be great. Thanks.

I'm very interested in this if anyone knows. My new fork has bosses but my CAAD2 cannondale frame doesn't. I don't want to have front discs and rear v-brakes, i just want all disc. please help!

Is there a way to weld the bosses onto your frame? This system is expensive and i read that it broke someone's steel frame. Is there a place that will just weld them on for like $50?
Eh, Maybe I should just run a V in the rear? I guess it is cheaper and lighter. Its just kind of weird.

or you could buy one of these for $50 and find out if they fit correctly with the dropouts of your frame.

I think i may have found what it is:

So called "Hammerhead." Only thing is, it doesn't look like it works with most bike models? I can't tell.
I think those are only for those specific models, but you could PM D8 if you think he wont see this post again.

Wow, that's great. Thank you for enlightening me. Does anyone know if this wil fit a CAAD2 Cannondale frame? I wish the desription of "fits most frames with flat rear dropouts" was a little more specific cause I'm not exactly sure what they mean.

After inspecting my bike, it appears my rear dropout is about as flat as can be so I'm assuming it will fit. If anyone knows for sure that'd be great but I think i'll risk it and get it unless I hear otherwise.

I've used the Brake Therapy, Woodman, and that A2Z (and under many other name) adapter on various frames.

The BT adapter works well, has good suport. It requires you to modifiy your hub with a special adapter from BT, so only certain hubs work. The Shimano hub adapter is finiky and does not work as well as the Hayes/DT Hugi or CK adapter. Removing the wheel requires a pin to be pulled so the adapter can release form the hub.

The Woodman adapter works pretty well, and is bolted to the dropout & brake boss. You must modify your hub by shifting the axle over ~11mm, so some hubs require a custom part (not available from them) or you can use thier special hub. Shimano axles shift easily and works well. Removing the wheel requires you to completely remove the QR skewer first.

The A2Z (mine was labled Ameoba) adapter just clamps to the dropout and any QR wheel that clears the adapter will work (unmodified). Because it is just clamped (4 bolts) it does not fit every bike (ie: breezer dropout don't work). Also, depending on dropout thickness, shape, design, the adapter can slip & rotate if the dropout is really minimal and there is not enough material to clamp to. I had it on a plate Ti dropout, and it held surprisingly well. The outer plate is steel, and will rust.

Cheers,

Tom

I have an A2Z disc brake adapter...

... on my old Infusion MXC pro hardtail that only had V-studs. I can now put discs on the back. The only difficulty I've had was alignment. The way that the adapter attaches to the rear drops, it's difficult to adjust all of the "cant" out of the adapter so you're caliper is in the same perpendicular plane as your rotor. Otherwise, since I've gotten it "close enough", it works pretty well
