Review on Shimano 9 Speed Double Braze Derailleur by Dan Hall

Thanks to my knowledge gained in practice I can attest that this derailleur is a game-changer. The shifting is smooth and precise, making for a more comfortable and efficient ride. The installation was easy and the build quality is excellent... i would highly recommend this product to any serious cyclist. The only downside is that it may not fit all bikes, so make sure to check compatibility before purchasing..
