The ORBEA Left Dropout Katu/Diem 17 is a genuine replacement frame component designed specifically for Orbea Katu and Diem models from around 2017. The left dropout is the part of the frame where the rear wheel axle is secured, and it plays a crucial role in keeping your wheel aligned, stable, and safely attached to the bike. Over time, dropouts can become worn, damaged, or bent due to impacts, overtightened axles, or everyday use. Replacing a compromised dropout with an original Orbea part helps restore the correct fit and function of your rear wheel.
This left dropout is engineered to match the original geometry and mounting points of the Katu and Diem frames, ensuring straightforward installation and reliable performance. Using the correct dropout helps maintain smooth shifting, proper disc brake alignment where applicable, and consistent wheel tracking, which is especially important for urban and commuting bikes that see daily use. Ideal for riders refurbishing a trusted city bike or repairing crash damage, this part offers a cost-effective way to extend the life of your Orbea and keep it riding safely and efficiently.
