Review: Shimano Dura- Ace 9. Shimano's new version of their top- level Dura- Ace groupset is comfortably their best yet with an extra sprocket taking it up to 1. We first rode 9. 00. Series Dura- Ace last June in Belgium and we were impressed, but we didn't get our hands on a set to review properly until early November. Since then, we've been getting in plenty of miles on the new kit to see how it stands up to regular use on our own local roads. And bearing in mind the dire weather we've had over the past couple of months, we'd say it has been a pretty demanding test period. To save you skipping back and forth to our previous article or to Shimano's website for tech details, we're going to include all that information here along with our review findings, so you can treat this piece as our definitive guide to Dura- Ace 9. The price at the top (. The front mech, chainset and cassette are available in different versions at different prices; we've used the cheapest prices to make up that total, so you might have to pay a bit more depending on the exact components you want. We've included the pedals in our review (below) but not in that overall price total. Shimano 2003 XTR Gruppo - Component Group reviews, user reviews, ratings. I bought the entire groupset and have not looked back since. More specifically, the crown race inside diameter is 33.0 mm and the frame cup outside diameter (or said another way.the outside diameter of the head race sections that press into the head tube) is 37.0 mm (and we believe all.

I'll put my cards on the table right at the start: I reckon this is the best groupset out there. It's lightweight, the shifting is smooth and requires very little effort, the braking is powerful and easy to modulate.. It's not cheap, of course, but for a no compromise, top- level groupset, it's not ridiculously expensive either. Dura Ace 9070 Di2 groupset 2,047 grams. Some loss of aerodynamics.

Could you post your FS bike and your groupset and components used. Another 49g if I went with the 9 speed 11-32 SRAM weight weenie cassette which would be 3/4's of a pound total weight loss (342g. If that all sounds a bit gushing, I'll try to explain why it's so good.. The diameter of the bracket is considerably reduced from the previous generation (7. Dura- Ace and everything fits together very smoothly. I've got large hands and I find the reduced size to be an advantage. People with smaller hands are likely to notice it even more. You can really get a tight grip right around the lever bracket when you're riding out of the saddle, with more overlap between your thumb and fingers, so you get loads of control when you're throwing the bike around on a climb or in a sprint. You just feel like you have more command over that front end. The rise at the front is high too, so your hands are never going to slip off. It's really simple to find the inner lever whether you're on the hoods or on the drops, even if you're wearing big winter gloves (and I have been recently). You'll never push both levers across accidentally. The next big difference you notice is the lightness of the shifting action. As you can see (above), Shimano put figures on it. What those numbers actually mean in the real world is that it's really, really easy to swing the levers across to change gear, but you still get a definite click to tell you what's going on. Shimano have also reduced the release lever stroke (the stroke of the inner lever) considerably. What's the advantage to all this? It's not going to make you ride any faster, it's just.. These details add to the overall improved feel. Shifts are completely reliable and very smooth, even if you're downshifting while standing on the pedals on a steep climb. There's no clunkiness whatsoever. Shimano really had that sorted before and it's a trait they've carried over here. Braking is more powerful than previously. Shimano have moved the brake lever pivot further from the bar and extended the brake lever slightly so the power is easily controlled whether you have your hands on the hoods or on drops (plus, they've altered the callipers and the cables, see below). Reach to the levers is easily sorted by peeling the cover back and adjusting a screw in the top of the body. You just tighten it to dial the levers in towards the bar. It's a very neat and tidy. Shifting effort is now more even across the range, with similar force required at both ends of the cassette.* Fast and accurate shifting* 1. Maximum sprocket 2. More equal shifting effort through the range. We say Shimano have redesigned the rear mech with a new spring mechanism that provides 'more equal' shifting. Usually, the higher up the cassette you go, the harder it is to shift. With the new 9. 00. Series rear mech, there's not much difference in the shifting wherever you are on the cassette. Shimano use new inner cables here. Instead of a PTFE coating on the outside of the cable as before, Shimano use a new polymer coating that reduces the sliding resistance to achieve lighter and quicker shifting. According to Shimano, the wide link design of the rear mech reduces shifting deflection and increases rigidity giving precise shifting over an extended time period. If you don't really notice your rear mech too much, that's a good thing, and I've had to do nothing here. I've been using the system for a couple of months and I've not had to adjust anything yet. The indexing didn't even go out of synch after a few days, which is normal with initial cable stretch. Maybe I've just been lucky – who knows? For a start, it's much, much taller than previously. The newly designed pull arm provides more leverage to help lighten the upshifting. The downshifting could hardly be easier. Plus, the front mech uses the same polymer- coated inner cables as the rear mech so that results in lighter shifting. You still get a trim function (so you can move the mech across slightly to avoid chain rub without moving to the other chainring) and an elastomer strip on the inside face of the front mech's inner cage plate to stop the chain rubbing on the metal. This works well and after a couple of months it's not showing a whole lot of wear. The capacity (the difference in size between the large and small chainrings that it can handle) is 1. T. The braze on front mech is . It draws quite a lot of comments because it looks distinctive. Some people don't seem to like the fact that the spaces between the arms are uneven. I can't say it bothers me even slightly. The idea is that the arms are positioned from an engineering standpoint to transfer power as best they can – taking the positions in the pedal stroke where we tend to apply most power into account – while allowing Shimano to reduce their number of arms from five to four, and thereby save weight. Shimano reckon this is as stiff as previously, but lighter (the 7. Did I notice any difference in the rigidity when riding? Nope, certainly not. The bolt circle diameter is 1. T combination) or a compact (5. T) – which makes things easier. You could ride standard chainrings at home, for example, and swap to smaller chainrings for a week in The Alps, for example, using the same cranks. Speaking of chainring combinations, Shimano have added new 5. T and 5. 2- 3. 8T options this year. I have a 5. 3- 3. I've used 5. 2- 3. One other thing that's worth mentioning: the new chainrings are the same thickness as the existing 1. Shimano don't envisage any loss in durability, and I certainly didn't notice any. Most of the chainset options are . Bottom bracket has smaller bearings than current model for light weight.* New improved sealing ensures 5. Available for conventional and Press- Fit applications. We say What do you want your bottom bracket to do? Mainlya) Get on with the job. Not creak. That's about it, really, isn't it? This ticks both boxes. It can be cool if you can service a bottom bracket easily too, but you can't do that here. It's a sealed unit so you fit it, use it until it dies, then you buy a new one. Shimano have fitted smaller bearings than previously to reduce the weight a touch. That does mean that although old tools can be used to fit them, they'll need a new insert. Shimano reckon that there's 5. That sounds a lot but there's not a lot of drag to start with. Is it enough to notice? Not by me, I'm afraid, no. It's available in both English and Italian threads, and in a press- fit option. Dura- Ace brakes deliver, with a new symmetrical dual pivot design and twin bearings reducing pivot friction and improving efficiency and controllability. Along with new low- friction BC- 9. Dura- Ace brakes give smooth, light operation with excellent modulation. Available with conventional mount or direct mount for aero road bikes (BR- 9. BR- 7. 90. 0* Smooth and light operation with increased modulation* Also available in direct mount version (BR- 9. We say Now these are interesting. They're built to Shimano's new SLR- EV design – in that they're an evolution of the existing SLR. The new brake is still a dual pivot design, but rather than having one pivot in the centre, each is positioned to the side, at the top of the drop section of the arm. Shimano describe this as a 'symmetrical dual pivot brake' – and it is. By repositioning the central pivot to the side, Shimano have shortened that brake arm. They say that this lowers friction at the pivot area and also reduces flex. Shimano reckon the chief benefit is that the new brake design increases power by 1. That means you get improved modulation – more control at your fingertips. It feels to me like an increase in power of more than 1. I guess it's highly unlikely that Shimano would understate it. The braking here is really strong, whether your hands are positioned on the hoods or on the drops, and it was impressive before. The amount of bite on offer is one of the best features of the entire groupset, and it's incredibly easy to apply – you require very little effort through your fingers. And the more powerful the braking, the longer you can safely leave it. You can buy the front and rear individually if you need to replace one, at . Rather than mounting via a central bolt, you get bolts that extend through the pivots and into your frame or fork. This BR- 9. 01. 0 version of the brakes (. The design comes with an in- line cable adjuster that features a quick release. The new 1. 1- speed cassettes are available in a range of sizes including a wide- range 1.
