Oski, I went for a long ride other day and the bike definitely shifts better. I also upgraded the chain on my son's road bike with a Shimano Ultegra chain which replaced a KMC chain and it shifts smoother and quieter. A good Park Chain Breaker tool (CT-3.3) goes a long way in saving money. It is amazing on how much a chain stretches after time. My son's old chain stretched 1/2 a link.
