Wheels Manufacturing is a company that makes replacement derailleur hangars among other things. They were recommended by a shop in SF for my Cervelo. Their hangar is a much stronger direct replacement for the stock Cervelo hangar. Now I am intrigued by what you see above. I am hoping to build up a single speed cyclocross bike in the next month, and I want to use my HED Bastogne road wheels for this project. Wheels Manufacturing makes this single speed conversion kit that should do the trick. The company is based in Louisville, Colorado, and all their product is designed and made in the USA.
