I'll be potentially looking for the above wheel for the 7sp shifters from my other post about Shimano index shifting compatibility. 700c 130mm axle spacing 7sp freewheel or freehub double wall rim sealed cartridge bearings
SunRingle email support and website are useless.
Anyone have any recommendations? Links would be preferable! Thanks

For future reference, remember that in the Shimano index shifting world, 5, 6, 7, and 8 speed all use the exact same spacing between cogs. The only difference is the number of cogs, with the larger gear counts getting wider and requiring a wider freehub and more space between the drive side spokes and the dropout.
If you've got 7-speed shifters that you don't feel like replacing but need a new wheel, you can use a wheel with a (readily-available) 8/9 speed freehub body. You just need to install a 7 speed cassette (with a spacer to make up for the missing cog) or an 8-speed cassette, in which case you set up your shifting to not use the largest or smallest cog. I hate the way 11t cogs feel under load, and rarely use them. All of my geared bikes are 8-speed, so I'm basically using 7-speed anyways. Etc.

MacG -- Why not just use a 12-x tooth cogset instead of an 11-x tooth cogset then?

I'd love to, but nobody makes the combination I would want of 12-32 or even 13-32 (woah baby!) so I'm stuck just ignoring the dinky 11t cog 95% of the time.
I shouldn't say nobody... There are a very select few ways to get this combination, but the last time I checked, they involve expensive parts, custom assemblies, or building your own custom assembly with the parts from two or more expensive cassettes with different spacers. Due to how often I end up buying new cassettes, I usually stick with the $25 or so SRAM 850 level stuff. I'm open to suggestions, however!

Sram has a 12-26 and a 12-23 cassette in the PG-850 series.Is that range wide enough for you? Probably not, according to your post. Considering that in even use, the smallest spockets should get the most wear per tooth, could you take a 12-26 and mate it to a used spider from 11-32?

I would be really unhappy if I had to give up my 32t cog. That's what kills me; they ditch the 11t in the road cassettes to get tighter spacing, but assume that anyone running a cassette with a 32t is going to want as wide a range as possible. Why won't somebody make a cassette designed for people who like a wide range (rather than a tight road spacing) but also really like low gears.
MacG's Dream Cassette*
13 15 17 20 23 26 29 32
* specs subject to change slightly if I ever have the chance to this setup in the real world.
I think Harris Cyclery (no doubt on Sheldon's insistence) does or used to sell a custom-assembled cassette similar to what I'm describing. I recall it being spendy, since they were literally assembling them from various new donor cassettes to get the gears they needed.

Harris cycles lists a 12-32 cassette as a Shimano cassette.
