wide range cassettes??

Not sure this is the right spot for this question , I figgure that only mechanics know.

Does this Cassette have 34/ 30/ 26 sprocketts?
Shimano HG30 9 Speed MTB it appears to jump from 34 to 28 sprockets.

the Shimano CS-HG20 Hyperglide Cassette (11-34T 9 Speed) jumps from 34 to 28

I saw a sram cassetts that had the right range. dont know what the number is.

Will fit on shimano SLX disc hub

I wish they would make one with even more low gears. But I know how the industry is, gotta catter to the fast movers.
I’m building a HD utility bike so I need a lot low gears. And at a low price. I don’t need shine.

Be sure to check all of the Shimano lines for cassette configurations. There are several. It took a bit of doing but I found a recently released 28-11 cassette that gave a better spread than the sram installed on my bike. And the shimano unit was finished much better, the sram unit looking rather cheap in comparison.

SRAM and Shimano cassettes are interchangeable save for a few odd-ball deep spline freehub bodies that Shimano tried to force on us.

SRAM's lower-level cassettes are quite the bargain, with good chrome finish and much lighter weight than any 8-speed road cassette that shimano ever offered.

I very much favor Shimano chain, however, with it's longer wear life and because it stays quiet, even with scant lubrication.
KMC is also a great chain at all price points, the only budget chain that I can recommend.

Consider looking at the crank instead. 22-32-42 triples are readily available with steel rings at low cost. Can't think of much that a 22-28 combo wouldn't let me handle.

Last time I looked at chains the KMC and the Shimano looked like they came from the same mold.

And the bike shoppe people never could convince me that the Sram was worth more.

I got a HG-50 then realized that I should stick with 8 speed cassette and chain. I have never used 9 speed chain and think there may be a problem with friction shifters....and I am going to use an old Suntour.

So the only 8 speed cassette with 34 sprockets the bike shop could find was the HG-31 but it jumps down to 28 from the 34???

I may have to live with it. I hate trying to find stuff on the net, it takes so long, and the shoppe catalogs are usual old.

If you had indexed shifters there would be a problem, but not with friction shifters -- they'll shift just about everything.

What combination of cogs do you want? 11......34 Fill in the dots. Next plug that combination into the Sheldon Brown ratio calculator linked below to see if it gives you the gear inches and percent change between cogs that you would find appropriate. Then lets see if it is available.

http://sheldonbrown.com/gears/

Since the difference between 32 and 34 is not really that much you might consider an 11-13-15-18-21-24-28-32 available in HG51, HG41 and HG31. That keeps the steps reasonably close. Amazon has a good stock of cassettes as do shops like Universal and with a $10.00 socket they are a snap to change.

Nerrow chain crankset?

I got one of the HG 31 cassetts, they do not have a jump from 34 to 28! It jump down to 26!

apearantly the only way to get the gears I need is to use a 9 speed cassette. And new chain.

But do the chainrings need to be closer together for the nerrower chain??

I am going to use an old Biopace crank set.

What specific chainrings are you going to be using? Hopefully, you're not going through all this wide-range cassette fuss just to use an old 52/42 racing double...

I was using an old cottered double crank from an early 70's 10 speed for awhile with a 9 speed cassette/chain without issue.
