I have a nice Tubus Cargo on my touring bike, but it doesn't look like it will clear the rotor on the disk brake. What is anyone else running in a similar situation? Any recommendations?

Have a similar problem with Hope discs and I looked into getting a special made up by a local engineering firm to suit the system. It could be done and not that expensive, but realised that as I only ever use a top bag- I can get by with a seat post rack. The one I now have is made by Amoeba, and takes my top bag with around 12 lbs of spares and Tools odffroad, so is pretty strong. I have not seen them recently but I believe it was TREK that made a rack that instead of being attached to the Dropouts- Attached to the Seat stays about halfway down. Don't know how good they are, but probably stronger than a seat post, and could take side panniers aswell.

I had teh same problem with our newly purchased Co-Motion Primera with Avid disc. Co-Motion's solution to this is to use a Sherpa rear rack made by Old Man Mountain (www.OldManMountain.com). The Sherpa is a nice rack, but the mounting is kind of funky. Rather than attaching to an eyelet, the rack is attached to the canti brake bolts and rear axle using an extra long quick release skewer they provide. I think a better solution may be for Co-Motion to mount the ISO fittings between the seat and chain stays like several other tandem manufaturers do.

We have a Tubus Logo Expedition that is mounted away from the pad by the use of a long bolt and a piece of aluminium tubing. You can find a picture HERE (http://www.xs4all.nl/~mmhoff/images/Logo_hinten_1_(Large).JPG).
The tubing is just above the axle and it serves to clear the Magura Julie brake. On another tandem with Avid mechanical brakes we have a similar setup. If you want, I can make a picture of that particular "arrangement".

Tubus makes an adapter that works like the Old Man Mountain racks. You can find it at Peter White Cycles (http://www.peterwhitecycles.com/tubus_racks.asp) (near the bottom of the page). I like the system a little better than the OMM racks because the quick release is shorter. I have an OMM on a mountain bike (rather had) and the skewer bent. It's just too long.

Are you talking about the Tubus QR Adapter? The copy says that is for a Logo or Cosmo model. Not sure if there is much of a difference, if any, but still...it would be reassuring if they included the Cargo model.

We have a Speedster with an OMM rack and didn't want the skewer mounted version so I took a 1/2" diameter by 7/8" long piece of aluminum rod (available at the hardware store) and drilled a hole through it (if you have a vice and cordless drill you can do this) and went to the hardware store and got a long enough stainless alen bolt to go through the rack, spacer and frame plus an additinal 1/4" on the inside of the dropout for a locknut for insurance. I spread the left side of the rack frame and then laid it on the workbench and bent the the lower half back slightly to realign the bolt hole. It works great and have had close to 70 pounds on it with no problem. You can mount it and if it's off center you can bend it carefully back to center. If you don't want to make one yourself you can call Channing at Old Man Mountain and tell him you need a disc brake spacer kit for a Red Rock rack and he'll send you one for a nominal fee. I recommend a stainless washer at each end of the spacer and at the locknut and of course a little grease.

Tubus says it's for Logo Cosmo and Vega but I don't see why you couldn't use it for a Cargo other than you'd have to limit the weight on the rack.
