Publicado Por En julio 27, 2026 Original owner of a set of two Shimano Dura-Ace 7800 10-speed rear derailleurs, designed with a short cage for road bikes. Made of aluminum and featuring a sleek silver color, these high-quality derailleur components are compatible with 10-speed bikes and are easy to install with a bolt-on mounting type. With a Japanese origin and durable construction, these rear derailleurs from Shimano are a reliable choice for improving the performance and efficiency of your road bike. Taken off of a Cervelo Soloist Carbon and Scott CR-1 that were converted to Dura-Ace 7900 many years ago to increase gear reach (rear casette size) for climbing.
