as my budget gets tighter, i gotta make saving where i can.
besides weight, what could be/go wrong with a cassette like this?

You may not like the massive jump to granny, otherwise nothing wrong.

Buying cheap consumables (bar tyres) made me the man I am today.

If you dont like the range get this one

don’t! ^^

Sram cassettes are awful strength/quality compared directly to Shimano.

cheap Shimano cassettes come in 11-28, 11-30 & 11-32 too.

HG51 cassettes can be found for less than a tenner

+ I am guessing you need a few more bits so get more stuff to make the postage worth while.

is it definitely 8 speed you need?

aye.
def. 8speed. i run old ultegra shifters w/ the thumbie mounts.
i think an hg 51 (also from rosebikes) might be the ticket.

ta muchly for your time and consideration.
