At 11-46, Shimano has currently reached the end of the range for a single-chainring drivetrain. But a solution is on the horizon. Garbaruk from the Ukraine has an 11-50 cassette that is compatible with the Shimano body. This allows you to push your drivetrain to 455% gear range compared to the original 11-46 teeth with 418% gear range. The 11-50 cassette weighs 299 grams, the largest sprocket is mounted with screws and is therefore replaceable - and not riveted as with competitor products. This largest sprocket is made of aluminum, the remaining ten sprockets are made of nickel-coated steel.

Garbaruk also offers a retrofit derailleur cage for acceptable shifting performance. This allows the rear derailleur to perform the massive balancing act between the smallest and largest sprockets and should ensure good shifting performance. Also available from Garbaruk are cassettes for Shimano 11-speed with 11-46 and 11-48 gradations. In Switzerland, the young distributor Ride On offers the Garbaruk parts.
