ouch! $128 for a cassette? when i can find chainrings for under $10?

i've already bought a new 11-34, HG-50-9, but checking online, i can get
an ALIVIO CSHG40-9 12-36 for $25.

with a 42 outer ring, that would give me a slightly better 16" low gear,
and a 91" top gear. close enough!

so 11-34 for everyday use, 12-36 on the touring wheel.

how about alivio cassette quality?
