Well guys and gals I'm gonna save you the headache I just experienced. Please do not purchase the WGS 37 tooth rear sprocket without buying the 11 tooth too. The chain will not go one without it.
Maybe I'm ignorant and you have to have both odd count or even count sprockets on the front and rear the same time. Just can not get the master link to get in both pin holes. If I could the dang chain would be soo tight I'd ruin the rear sprocket in no time.
Truly disappointing
