Oh, I like the little gizmo-y things... but that stops when it comes to my derailleur deciding to throw itself into the spokes through no fault of my own, when it's 5, 10, 20, 150 or however many miles from home.
I've thrown a derailleur into my spokes through faults of my own... I ONLY had to walk only a mile home carrying the rear end of the bike, and that sucked. Plenty of time for me to rationalize my poor decision making...
I think Suntour tried to get way too cute with it. You want a Suntour triple pivot that won't blow up on you? Try LeTech. Or better yet, a 2nd generation Mountech with the 13T pulley instead of the enclosed blowey-uppy-pulley. Just as cool, probably more rare and that bigazz pulley is pretty cool.
But even WAYYYYY BETTER- a Cyclone MII GT or an XC Comp or XC Pro... no useless 3rd pivot and a well proven record of reliability, rugged good looks and badassery... sounds like I'm talking about a lumberjack or something...
But for unique and badass and working well... Any of the Suntour triple pulley derailleurs are fantastic.
You may notice most of these derailleurs are on one bike- I've swapped out the derailleur on my 720 bunches of times, I've used XTR, XT, Duopar, Cyclone, Cyclone MII, XC Pro, XC Comp, LeTech, XC, and now Dura Ace on this bike. Maybe I'm even missing a few.
If I wasn't going with a 10 speed indexing system, I would have probably kept the triple pulley Suntour XC on there. It shifted as nicely as anything- I would say it was a tie between the Duopar and the XC triple pulley- and the triple pulley never hosed on me like the Duopar did. I did up the lower 2 pulleys with red Bullseyes and the jockey pulley as a "titanium" colored Bullseye- that was badass.
My Stumpjumper came to me with an M735 XT RD and an LX/Weinmann rear wheel, and the stock front wheel. The stock RD would have been an 1st gen Mountech. It doesn't take much to tell me that RD blew up sometime in the early 90s and the whole rear wheel needed to be replaced. The original owner of that bike told me that was his commuter. It wasn't a dirt bike, that was his "ride over the Golden Gate Bridge on his way to work 5 days a week" bike.
Yeah it's cute to have a death defying derailleur on there. Yeah, it's cute to say you taunt fate instead of tempting it. While the bike is a whole lot for lookin' good, it's more for riding. But you're not riding and you're not looking good with your RD tucked into your spokes and cussing out words sailors don't even know.
