I now have a hebie chainglider for the rohloff on our tandem. The chainglider is difficult to buy in the US, I finally found both components (front/rear) from Spain for a decent price with low shipping fee. Our timing and rear chains are on the same side of bike, using a double chainring at the stoker. Thorn tandems are also of this design. I was concerned the chainglider might not fit onto a double chainring. After a new chainring, addition of chainring spacers, some adjustment, and a bit of oil, the whole thing works great. No interference with the timing chain. We often ride on dusty trails, so looking forward to a longer life from the rear chain. We go through 3 or 4 rear chains (~2500 mi) for every timing chain (~9,000 mi) replaced. The whole contraption also looks great. Thanks to this forum for showing the way.
