It gets mentioned a bit in various threads here from time to time but deserves its own reference. Not just a great vintage cycling resource but a great website full stop. Beautifully and entertainingly written, great pics and an insane collection that's so niche and yet so satisfying.
The page on the Cyclone GT 5905 2nd style was enough to convince me to ditch my beloved Dura Ace when sourcing parts for my Toei Randonneur... And I can say that everything below is correct. Shifts beautifully both front and rear. Front mech handles going from a 26t to a 48t front with ease. The rear mech's jockey wheels come with sealed bearings FFS! That's when you know it's overspec!
"With a clever cable route, a relatively low price, exceedingly light weight and with a great shift, the SunTour Cyclone GT was a miracle. To this day the Shimano XTR is heavier than this Cyclone GT - proof of the simple purity of the single-sprung pivot slant parallelogram design.
The second style of SunTour Cyclone had a slightly redesigned rear knuckle and a captive short hanger bolt (with a distinctive serrated edge).
Typically for touring Cyclones, this example is well used. The SunTour Cyclone GT was not just for decoration or a talking point - it was the gear of choice for many a cycle tourist setting out from Britain to Istanbul or wherever. For the cognoscenti it was what you fitted on your hand-built Mercian or Bob Jackson - only blow-hards opted for Campagnolo. I loved it.

There's also an FB page I see www.facebook.com/disraeligearsderailleurs/ which has some posts as recent as 2018. What is it about 2018? It's the year I stopped posting here and it's also the date of Stella and Busaste's last posts here too. Weird...
