The ultimate set to increase the range of gear ratios on a gravel bike with an 11-speed GRX group and just one chainring. By upgrading to the 11-50 cassette and replacing the rear derailleur cage and idlers, you can climb any incline that was too steep with the maximum standard cassette. The bandwidth increases to 455% and you also have gear reductions available. A positive side effect: you can now mount a 42 mm blade or more at the front to get up to speed on the flat, but it's still easily enough at the back.
Included in the delivery are:
the 11-speed cassette 11-50. Except for the aluminum 50, the body is milled from one piece of steel.
- the long rear derailleur cage to cover the entire range.
- two large pulleys in and teeth with industrial bearings.
- lock ring and spacer ring.
For me in the always current combination black/silver.
Attention: you need a fairly long chain at the back due to the large plate, with a 42 chainring at the front it should remain the standard Shimano 116 links or longer. The conversion kit is intended exclusively for the rear derailleur RD-RX 812.
