Ritchey parts are designed by Ritchey but built by others. They are NOT rebranded parts. Ritchey parts for the most part are good part but there are occasional clunkers. I would avoid the single bolt seat posts as I've never been able to tighten them enough/put enough anti-slip on them to prevent the saddle from shifting. I find Ritchey Comp and WCS are a great combinations of price, weight & strength. And if you want something that is light look for Super Logic. Weight Weenies say that Super Logic parts are some of their secrets for building reasonably affordable superlight bikes.
