Really great quality group set, a lot cheaper than it's competition. No need for new freehub (uses the standard shimano one), so just remove your set and and slip this one one.
The 50t cassette is great, the size of a dinner plate, it really helps on the climbs.
Shifting is smooth and positive - everything you could ask for.
