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.
If you want to see exactly how it works and what it brings, you will be helped here in the workshop with the bikeboard. The manufacturer describes it here .
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.
