internal gear hub on a frame with 145mm dropouts

Hi all, I am wanting to put an internal geared hub (either an Alfine 11 or the Rohloff) on a Cannondale Road Tandem (aluminum). From what I have found all of these hubs have a 135 mm spacing, whilst the Cannondale frame has 145mm dropouts. Does anyone know of a way to get the shorter axle to fit the wider frame. (note that I do not currently own the hub or frame, so I cannot measure anything)

My thoughts so far: 1. if the axle happened to be long enough, simply add some serated spacers, 2. replaces the axle (I have a feeling it is not removable), 3. perhaps there is some sort of extender nut/bolt thing that can be threaded on the existing axle to make it longer, 4. bend the frame (though I think is bad news with aluminum.

Any ideas of how to get the narrow hub on wider dropouts???
Thanks

It can be done. If you head over to MTBR.com go the the internal hub forum, also in the tandem forum. Nate, gave all the details of how he installed a Rohloff into their 145mm Cannondale mountain tandem. FWIW, they ride it off-road, so on-road should be no issue.

Nate goes by the call sign Speedubnate or similar. Last I knew, he was also a moderator of the internal geared hub forum.

R&E Cycles in Seattle offers a tandem with the Rohloff hub installed. Also lots of info on the hub itself.
