Why I picked this over the SRAM PG850 11-32T
I weighed the 11-32T version of this cassette at 302g.
Even though this is about 25g (0.88 oz) more than the SRAM PG850 8 Speed Cassette (as measured by customer Gamblore 151), I feel this very slight weight penalty is a good compromise for better spacing between gears.
The HG51aw (11-32T) is the following:
11-13-15-18-21-24-28-32
While the cogs of a comparable PG850 are:
11-12-14-16-18-21-26-32
With a cassette like this, I'm more interested in the low ratio (large sprocket) end of the spectrum. The Shimano has 4 tooth jumps between the largest three gears, while the SRAM has 5 and 6 tooth jumps.
As a side note, Shimano uses the following letter codes for its 8 speed cassettes:
-an 11-13-15-17-20-23-26-30
-ao 11-13-15-17-20-23-26-34
-aw 11-13-15-18-21-24-28-32
-bf 11-13-15-17-19-21-24-28
