I'm contemplating on what gear setup to do and was wondering if anyone knows the part number for a JT steel rear sprocket 46t? I have found 45t for the 05 636 on amazon but can't seem to find the right part for the 46t.
You should have a look at supersproxusa.com! I have one of their sprockets on my bike and I love it! They make the stealth sprocket which is what I have and it has an inner core made from aluminum, but the teeth are made from steel, so it is lightweight but last 3 times longer than an aluminum sprocket! I really recommend them.
