What replacement sprocket/cassette for early 1990s 7-speed

[fendervg]

Hello from a new member - currently in the process of rebuilding a 1991 Beara hardtail custom racing (hand built cro-mo, made in Ireland) frameset with M730/732 XT components.

Just wondering, seeing as it's generally accepted as good practice to replace the sprocket cassette along with a new chain, which replacement 7 speed one people are using? I can see the Shimano HG40/HG71 widely available, but what kind of quality are these and are there any other recommendations?

The last time I did a retro build I purchased a custom sprocket set from Harris Cyclery, sadly no longer around.

Many thanks.

For 7 speed I tend to use SRAM cassettes as they seem to work well and are readily available at a reasonable price

Shimano 11-28 7 speed CS-HG41-7 is my go to, very light also at 225g. I use KMC Z51 (6, 7, 8 speed) chain

Both very reasonably priced, most of my stable is 7 speed

Thanks guys, will check these out.

So it looks like two good options are:

SRAM - 12-32t

PG-730 Cassette - CS-PG-730-A1 - SRAM

PG-730 Cassette, CS-PG-730-A1, SRAM. Cassette technology optimized for MTB. More reliable. More durable. Better performing, thanks to an optimal tooth profile and shift ramp design for qu...

The HG41-7 offers SHIMANO's HYPERGLIDE shifting across its 7-speed range. It is compatible with both IG and HG chains.

Had good results with SRAM 7 speed.

Personally I'd go with a 12-32 like this because I like low end and live in a hilly place

Sunrace also sells 7 speed cassets, but sadly no 32 low gears.
