In addition to proprietary wheels, the Tarmac Disc has a unique derailleur hanger that puts the Shimano rear derailleur in the correct place. A standard 135mm disc-brake wheel can be used on the Tarmac Disc, the company says, but that would require changing derailleur hangers, too. And even then, the little ring/little cog cross-chain combination is “not recommended.”
