The chainrings may be expensive, but they last quite long and the ability to swap between compact and standard rings on the same crank is brilliant. Photo: Brad Kaminski VeloNews. Will Kymlicka Contemporary Political Philosophy An Introduction Pdf. com Two years, over 10,000 miles, one conclusion: Shimano’s Dura-Ace 9000 mechanical group is the best human-powered drivetrain the world has ever seen. If you’re a weight-weenie, look to SRAM, home of the best weight/cost ratio in the industry. If heritage and beauty are paramount, there can be nothing but Campagnolo and its striking carbon curves. But if clever, precise engineering and absolutely flawless performance gets you flush in the face, Shimano Dura-Ace 9000 is the group for you. One can argue cost/benefit ratios and aesthetics and personal ergonomic preferences until the cows come home, but to do so is to miss the point.

In the 9000 drivetrain, Shimano has a kit so impeccable it rivals the company’s own electronic groups. Shift performance — and that’s what really matters here — is in a class of its own. How do we know? We’ve been living with it for over two years. That’s the idea behind Stress Test reviews, which you will see more frequently on VeloNews in the coming months. Normally, gear moves through the VeloNews tech department relatively quickly, out of necessity. A few months on a single product is all review schedules allow.

But for this round of Stress Test, we put Dura-Ace on the machine of a separate tester, who thrashed it across two full seasons. Plx Pci6140 Aa33pc G Driver Download. He reported back, and we combined those notes with our own opinions formed from shorter test periods. In this review, we will skip long lists of features in favor of a narrow focus on those we feel matter.

There are already plenty of stories that can tell you what Dura-Ace 9000; we want to tell you what it does. This is the first of three Stress Test reviews of top-tier mechanical groups, a category we still feel merits close inspection. SRAM Red is up next — expect that in a few weeks — and Campagnolo Record will follow. We want another few months of riding on the Record group before forming firm opinions. Grmculfrer Es Dvd Iso Burning. Shimano Dura-Ace 9000: What we love A good group doesn’t distract with gimmicks.

It simply works, when and how you want it to work. Swipe the left shifter, in either direction, at any time, under any load, and the shift is perfect, instantaneous, and reliable. It’s uncanny. The updated front derailleur now features a longer arm for more leverage.

Combined with the new ultra-stiff chainrings and the front shifting comes incredibly close to the power and accuracy of Di2, with the added benefit of human-touch finesse. The one-size-fits-all spider is so clever that it’s been widely mimicked in the two and a half years since its debut. Racers love the freedom to swap between standard and compact chainrings on the same crank, to alter gearing to suit various courses. Pro mechanics now travel with piles of rings, not boxes of cranks.

The chainrings used to be incredibly expensive, more costly than many complete cranksets, but have recently plummeted in price (read into that what you will, relating to Shimano’s product cycles). They are impressively durable, too. Rings were changed once, at 7,000 miles, though they still had quite a bit of life left. Rear shifting quickly becomes an act of muscle memory, requiring no thought or planning. No second-guessing, no easing up a gear. Shimano’s slick cables and housing keeps rear shifting smooth for a very long time — perhaps too long, as you will see below. Both front and rear derailleurs are designed for even lighter action than before, harkening back to the glory days of Dura-Ace 7800.

The ideal weight behind each click of the shifter is a matter of personal preference, and some testers did make it clear that 9000 felt a bit too light, particularly for those used to the hard click of SRAM or Campagnolo. The brakes are standout performers amid a sea of excellence.

SRAM’s cam-actuated Red brakes offer great power and modulation, but are finicky to keep adjusted properly. Dura-Ace offers more power (but only just), even better modulation, and easy setup. 9000 brakes are designed for today’s wider rims, though they do lose some power on rims over 25mm or so (outer width).
