These are great looking wide-range 9 speed cassettes. We bought them in the early Hillibike days but never used them, probably because we didn't know what derailer to pair them with for friction shifting. They're here and discounted from their regular retail price, but it's on you to figure that one out. Maybe one of those drop tabs? Or just use the corresponding indexing stuff, which we don't sell but is widely available.

We got this email from customer Winter, who is using Silver2 shifters:
The product page for this cassette says something about it being hard to get set up friction. I purchased the matching derailleur from elsewhere, and set it up friction. Like a super wide range double, shifting up the larger jumps was a little clunky in the stand but everything smooths out on the road. It’s super doable!

These come with a thick spacer that almost looks like packaging, but it isn't. You need dat. Slide it on the freehub body before the cassette.
