This is a great upgrade from my original Sora considerably lighter and a much smoother gear change, has brought a new life back to my old frame.
This is a solid Groupset for riders of all skill levels. Shimano makes great components and I am very satisfied with the product. The shifting is clean and smooth the crankset is high quality and very lightweight for not being carbon. I recommend this groupset to all my riding friends of all skill levels and recommend it for anyone looking to upgrade to a quality groupset for a reasonable price.
