What is RM Cash
JAMES in NY
I really like primary gear sprocket I redo bikes for kids and they last a really long time so if you're not a professional and don't mind adding the extra weight their top-of-the-line

Looks great on and we’re not heavy at all.

I love using the primary drive chain. I do 12 races a year and normally just replace the chain once a year.

Bolts are too short only about 3 tthreads in nut had to go to store and get longer bolts, also the heads are T20 not hex (just FYI)

I’ve ran this chain and sprocket set up for the past couple of years and have never had a problem with it to this day! Highly recommend

They last for a long time and cost so little. I don't know how you could go wrong.
