SHIMANO Ultegra Di2 Road Group R8170 hydraulic Disc Brake 2x12

Description:

    • With the components of the 8100 Ultegra series, Shimano offers you an excellent price-performance ratio. You can see the Japanese company's years of experience in every detail. Whether functionality, durability or weight, top values are achieved everywhere. Shimano is also revolutionizing Di2 components with this top groupset. From now on, shifting commands are transmitted without cables. The wireless technology with the transmission protocol developed exclusively for this purpose guarantees you the fastest shifting operations that are currently possible in the bicycle sector. To make the rear derailleur and front derailleur as compact and streamlined as possible, these components are still connected to the new internal BT-DN300 battery via an E-Tube cable.

      Ultegra Di2 shift lever ST-R8170 set and BR-R8170 flat mount disc brake set
      One push of a button and the gears are engaged quickly and reliably. The precise pressure point of the levers ensures that the gear changes are only triggered when the rider consciously shifts gears. Accidental operation is not to be feared. The wireless chip also scores points for its low energy consumption. The CR1632 button cell has a service life of over 1.5 years. This system is fully customizable with the Shimano E-Tube app. This allows the shifting logic to be adapted to the rider's preferences. Among other things, the shifting speed can be set, a fully or semi-synchronous shifting mode can be selected and the program buttons on the lever can be assigned specific functions.
      When braking, SERVO WAVE technology gives you optimum control over your bike at all times. This offers unparalleled modulation and sufficient power. But it's not just the inner values that are impressive. The ergonomics have also been significantly improved. The grip recess is better shaped and the rounded brake levers lie securely under your fingers even on long descents. The grip width can also be individually adjusted. The completely redesigned ULTEGRA BR-R8170 brake caliper enriches the world of road bikes with a new level of control, optimized modulation and unprecedented braking power. The new design minimizes brake rubbing. In addition, despite its compact size, this system is quieter and easier to maintain than ever before.

      FC-R8100 2x crankset
      The Ultegra FC-R8100 crank not only converts your pedal power into propulsion, with its high rigidity it also ensures extremely fast and precise shifting. The high shifting precision is supported by the optimized chainring design.In order to keep the weight low, the Japanese continue to rely on the proven Hollowtech II design of the crank arms. The crank is available in gear ratios of 52-36 teeth and 50-34 teeth and with crank arm lengths of 160 to 175 millimetres.

      Rear derailleur RD-R8150 Di2 Shadow
      The compact Ultegra 8150 rear derailleur delivers lightning-fast yet precise shifting. Even under medium and high loads, thanks to the low profile design and Shimano Shadow+ technology, gears are changed quickly and without major noise development. There is no noisy clunking or rattling with these high-tech components! Despite its slim dimensions, the rear derailleur houses the battery charging port and the wireless mode button. With just one cage length, the rear derailleur shifts on cassettes from 11-30 teeth to 11-34 teeth, thus increasing the versatility of the top Japanese component group.

      FD-R8150 Di2 front derailleur
      The Ultegra R8150 front derailleur is more compact than ever before and a real powerhouse. The front derailleur shifts absolutely seamlessly between the chainrings and performs its shifting operations with digital precision in all conditions. The reduced frontal contact surface has also made it possible to reduce air resistance.

      BT-DN300 internal battery
      Integrated battery of the latest generation, which is recessed in the seat post or steerer tube. The internally routed cables give the road bike a tidy appearance. The integration of the battery into the frame also reduces the number of attachments that stand in the wind. The battery can remain in the bike for charging.

      CS-R8101 cassette
      The revised CS-R8101 cassette makes shifting even faster and smoother. You can shift gears without hesitation even when exerting maximum force on climbs or sprinting to the finish line. This is made possible by a slightly optimized tooth profile.
      Shimano also uses Hyperglide+ technology, which has proven itself in the off-road sector. This significantly reduces the time required for both upshifting and downshifting and, compared to conventional HG systems, enables smoother pedalling.
      Despite the new design and the additional 12th sprocket, the CS-R8101 cassettes are also compatible with previous 11-speed Road freehub bodies.

      Ultegra chain | XT chain CN-M8100 12-speed
      The CN-M8100 is characterized by its particularly smooth chain operation. This is not only noticeable when pedaling, but is also noticeable acoustically thanks to a 4db quieter drive. Thanks to a new chrome-plated surface in combination with the proven SIL-TEC coating, the service life of the chain has been kept at the same level as the M8000 chain, despite a smaller outer width.

Stable, attractive, and easy to turn into a table with your choice of top
Size: side table leg
The X-shape of the table legs - constructed with solid metal flanges, T-joints, X-joints and 1-inch diameter pipes - provides a strong and sturdy base for a wood top. The legs have adjustable feet pads to prevent scratches and ensure stability. Assembly of the legs is relatively simple (the instructions are clear) but you will need your own tools to attach a top. The industrial design is especially well suited to rec room or finished basement use. I am adding a 28" diameter raw edge slab of wood from a recently felled tree as the top and it is very attractive. (Photo unavailable because after I made certain it would work I sent the slab out for drying and finishing.) If you want a custom table and have a particular piece of wood you want to use, these legs are an excellent choice.

Very nice kit: Beware it is NOT heavy duty plumbing pipe though!
Size: side table leg
I want to give this kit a high rating, but I need to address the "truth in advertising" bit since there may be an important disconnect between what you think you are getting and what actually comes in the box. Black plumbing used for shelving or table legs is part of an important niche in interior design. I like the industrial loft look myself and have a variety of glass, steel, and masonry elements in my home. This kit fits that look and provides plenty of "strength" for most domestic uses, like shelves or coffee tables. But they are NOT "industrial pipe" or "maximum durability pipe." Note the phrase "cast iron finish feet," which together with the other claims might lead you to think these are cast plumbing fittings. They are NOT! The feet and flanges feel like electrical conduit fittings, and the pipe sections are likely aluminum. They might be electrical or they might be multi-use, lightweight pipe. While all this might lead you to think that you're getting a truly retro, heavy-duty pipe kit made of black plumbing pipe, you are not. But, does it matter? Depends. I find the lighter pipe's smooth finish a nice "tone-down" from the rough plumbing look. All together, this kit provides plenty of strength for most furniture and the rustic pipe look, but with a nicer, lighter finish. To me that is a plus--this is a very nice kit and costs less that if you'd pieced it together from real plumbing parts (I priced it out to compare), and looks retro but cleaner. I knew what to expect because while I got this kit free on Vine, I had purchased a nearly identical kit from another seller last year. So, I'm giving it 5 stars for what it actually is and for the price, JUST BE AWARE THE NARRATIVE IS MISLEADING. Which is unfortunate because just like some people might want the heavier pipe, I'm betting more would be attracted to the look with a cleaner, lighter feel.

Lovely and sturdy for what I needed!
Size: 3 Set 4-Tier, Planks Not Included, Size: 3 Set 4-Tier, Planks Not Included
We LOVE these shelving brackets! We were moving our books from our office space to turn that room into a nursery and I needed something that would be sturdy and off the floor since my books were moving to our living room. These are extremely sturdy, and also go with our curtain rods and other furniture that has this industrial style. The instructions for assembly are simple and easy to follow, I would just ensure you have an extra set of hands (this isn’t a one person job) we ordered the 3 pack, but ended up only needing the two for the space on the wall and they still hold the weight well. Also this is a work in progress so please disregard that I don’t have the other two shelves here😂 Definitely a high quality and great looking alternative to some other brackets out there!

Takes time to install right.
Size: 3 Pcs 5 Tier, Not included planks, Size: 3 Pcs 5 Tier, Not included planks
Saw a few complaints about this product in the reviews before ordering but gave it a shot anyways. Took a little longer than I would have liked to install, but was only time consuming, not difficult. I made sure at least 2 screws on each base plate were into studs so it's more than sturdy. Hung each of the 3 brackets by 1 screw, marked the rest of the holes, took it back off the wall, installed anchors where needed, and finally screwed each back up fully. And for the people saying that the threads don't line up once snug, try switching out a fitting or pipe so it's a different thread mesh. If that doesn't work, just over tighten the fitting. Furthest one I pushed was nearly 3/4 of a turn past finger tight. I don't have a single loose connection on the whole shelf. My wife can't wait for us to go to lowes tomorrow for the wooden shelves to finish off the bookshelf this will be for her.
