Well, The old 7 speed cassettes I have are bricks and been tough trying to find a Tioga/Real/Goldtec/SRP 7 speed HG cassette with NO luck.

Looking at new stuff, I see the HG41 weighs in at around 235g
But the HG50 looks heavier, as hasn't the drilled bits and as much cut aways.
The SRAM PG730 doesn't look too bad, but probably weighs more.


What could I or should I go for in regards light weight and good performance out of these three?

If you don't mind skipping the retro then

Or drop to the road 12-27 for another 20 or so grammes

With the wider ratio's you can drop your granny ring, bolt and spacers as well, and only have 1 less gear ;-)

Other than that, read the previous posts.
Just grab what you can... HG40 is easy

This would be more 'fun'

I presume you've seen the 8sp 950 cassette in the for sale section?

Yea - remove one of the cogs as suggested. In fact I think it's the smaller cogs that are steel so removing one will satisfy your inner weight weenie.

1.2mm across the block, you don't count the first cog, only 6 shifts.


Only .6mm if you set up perfectly on the middle sprocket!
