Why bother when Shimano make an 11-46T cassette? The 11-46T has a huge, clunky 9T jump from 37-46T meaning that the shift to the biggest sprocket feels like a shifting into a granny ring.
Adding a OneUp 47T sprocket to the Shimano 11-42T cassette gives you 5T jumps in the bigger sprockets - 37-42-47T - making the lower gears extremely useable. The 47T requires no derailleur cage mODIfications, so its a quick and easy install.
