My Raleigh bike came with Ritchey wheels, DS Pro in front, OCR Pro in rear. Rim designation is ETRTO #622-14, 6061 T-6 Alloy. Just wondering how low in the wheel food chain these sit, i.e., how much benefit I can expect to get from better wheels. I guess the model must be several years old, because I can't find all that much information online. Any insights appreciated.
