In the first thread about the Suntour rebirth we talked about this and I guessed that a customized 8 speed Shimano/SRAM cassette using 6 cogs would work. I compared 8 speed cassettes (minus the two smallest loose cogs) to a Ultra 6 Speed Winner freewheel. The spacing is nearly identical.

L-R: Shimano cassette, Suntour Winner, SRAM cassette
So in theory, this short 120mm cassette hub could be used on old frames and we could assemble our own custom cassettes to achieve the gearing we want. This would solve the freewheel challenge of finding NOS ones with the desired gearing, or resurrecting old freewheels. It would also provide the added benefit of adding shaped and ramped teeth for an improvement on shifting.

Probably some sort of Legalosity.
As I recall, the company that was SunTour is now SR Suntour.
Sort of like how the Cleveland Rams became the LA Rams which then became the St. Louis Rams, but then Cleveland got the the Browns which then became the Ravens and then Cleveland got the Browns again- but it's not the Browns that were there 15 years ago, and not the Rams which were there 50+ years ago- despite the history behind the cities and franchises.

The cranks look nice, but for the same price you can buy the Velo Orange 50.4 crankset and they include two rings (30/46).
Are the adapter spiders worth that much to people? I'm a little confused, but what's the point of buying 50.4 bcd crank arms just to use an adapter to work with 110/74 or 130/74?

Excellent comparison. Those new Rams just can't compare to the old Rams, or the middle Rams.
I wonder if they'll ever invent software that automatically searches, then merges threads that "belong" together. (?) And where's the "scratching your head" smiley? I need that all the time, & it's never there.

This hub is going to make for some very slick SS conversions on older frames. A free hub, a 5 BMX cog and a spacer — DONE — and without radical wheel dishing. I wish it had come along a couple of years ago.

Ya know, I forgot I have a VERY nice set of SR cranks in the basement. They look a heck of a lot like Campy Record cranks, and have 52/40 chainrings. It's kinda like the modern ones copied the older ones' idea, on chainrings, but they trimmed it a bit to 52-ish/39-ish, and still shrinking on the inner. I bet they'd work out great, with my Cyclone derailleurs.

That's the obvious answer to a different question. Under trademark law Sakae Ringyo Suntour, the successor in interest, holds the right to the "Suntour" mark for bike parts. Therefore others are prohibited from using the name no matter their relation to the old company.
Why "XCD" was the question. XCD was a middling Suntour mountain component group.
But then you could ask a similar question about Shimano: why re-use "Dyna" as in "Dyna-Sys" when it was part of the name for the old AX aero component group.
But then, who really cares about such etymology, eh? Is what it is.
Personally I would have come up with a more novel name in order to distinguish my mark from the past. For example, I'd never use "Bio-" in any ergonomic bike part simply because "Bio-Pace" is such an endless laughing stock.

there is a (i am in the) market for classic aluminum, well made parts for sure (look at paul, phil, white ind.)
i think the profit rate is not the same, but the pride is there...
6-7-8sp derailleurs, nice cranks, backward compatibility, etc.
sorry but all the new gruppos, and all the carbon stuff, (with some exceptions) look like batman s#!* ... i am not into that stuff. i am not a cyborg, i am not an EPO user, i am not satellite-linked or iphone-triangulated to strava or my sponsor. just give me a classic steel or alloy frame, a bike i can fix and overhaul myself. cup and cone prefered but sealed will be tolerated in some cases. classic wheels, classic spokes, alloy rims. doesn't need to have machined brake surface. 6,7,8sp is the most I will use.

I must have similar. They are stamped SR on the back but are elegantly pantographed as 'Miyata' on the show-side. 53/39T changing on a Suntour MTB XC RD.

I bumped that this morning wondering the same exact thing.
Somewhere, on some thread, someone mentioned that the Sun XCD rims are "soft." I don't know if that meant the user had actually used them, or "heard" they're soft.
I'm still eyeing up the Sun XCD rear derailleur. It looks like the Sun XCD front derailleur is made for doubles only.
I have a set of Suntour XC Pro cranks for my "someday" build. I wonder if these would be more appropriate for a 10 speed type build.

Bikes: '92 22" Cannondale M2000, '92 Cannondale R1000 Tandem, another modern Canndondale tandem, Two Holy Grail '86 Cannondale ST800s 27" (68.5cm) Touring bike w/Superbe Pro components and Phil Wood hubs. A bunch of other 27" ST frames & bikes.
Rather, more technically true, is any Shimano cassette cogs with the spacers of your choice. Cassettes that utilize carriers and riveted cogs wouldn't make sense because you'd be stuck with that block and spacing. However, anything that can be individually mounted without a carrier, could be used with the spacers of your choice. Does that make sense?
I thought the company was really trying to reach back to it roots. ABSOULTELY building a SunXCD bike now, including their rims. And I hate 622/700c as I'm a 630/27" guy (rolls smoother and gives better long crank clearance). Very fascinated with their short cassette hub, I find it awesome that their derailleurs are 9/10 but their shifters are 7/8. Can't wait to see what comes from them.
Most people never knew the quality of Suntour kit. I have bits that have come on bikes from the Superbe and the Superbe Pro groups and some random XC Pro stuff as well. I'll say this, their quality is every bit better than the equivalent Shimano groups at the time. The fit & finish on the Superbe and Superbe Pro stuff couldn't be had from Dura-Ace or Ultegra of that era. The looks and polish wasn't even close.
I love this announcement. Especially since Campagnolo is riding on reputation only and not striving to make great components with titanium and pushing the envelope, but just trying to survive with their branding. I still believe that the "level" of Chorus and Record of the 8-speed titanium era can't be had anymore. It may say Super Record, Record and Chorus, but it ain't.
The world is a better place with the remaining companies of the Suntour group that can last, still thriving. Long live SunXCD.

I have a question for all the bike gurus. Can I build a steel All City sport touring bike in 60 cm, with all new Suntour components, and get the smooth performance that I have been cobbling together from 25-30 year old components on CL, eBay and BF? If the answer is yes, I am very happy.
