Fouriers MAGE SK Sprocket CR-DX004 [Size: 42T] [Colour: Green] - Green

At Fouriers we admire other manufacturers for their innovations, but sometimes we cant help to find some flaws and an urgent feeling to improve it. Thus weve done the same for the increasing popular 40t/42t sprocket. Weve noticed a major issue for most 40t/42t sprockets when pedaling backwards the chain easily drops off. The MageSK (aka CR-DX004) is an improved design that doesnt suffer the same problem and besides, it looks great.

Furthermore weve seen that upgrading the cassette to a 40/42T will suffers smooth shifting in the lower gears, due to the removal of the 15T or 17T sprocket. It is therefore recommended to also install a 16T sprocket along with the 40/42T sprocket on the cassette for the smoothest shifting. But we are Fouriers, we dont want OK performance, we want YEAH performance.
