Pros

The derailleur handles the expanded 48-36 length just fine. The chain shifts fine onto the 36 tooth sprocket. The 11-34 cassette comes with a spacer that goes between the hub and the largest cassette sprockets.

Take care when installing the lock ring. No issues shifting on/off the big cog. All other shifts are crisp.
