Shimano Dura-Ace bottom bracket axle (or BB spindle if you prefer), hailing from Japan and in production during the 1970s (yet still new & unused after all this time). Made from steel and weighing in at 148 grams. A fine choice for keeping your vintage bike authentic, but also great for any other compatible bike.

The very first Dura-Ace axles were stamped '333' with a date code that is specific to early Dura-Ace. The axles came with the GB-100 chainset but carried their own part number (137 0100), the specification remained the same when the FC-7110 chainset was introduced, so they are compatible with both models.

If you're taking part in L'Eroica or any other vintage event, this is fully compliant - so rest assured, the pre-1987 police won't lock you up for having the wrong axle!

HELP SECTION
We've provided reference below to illustrate how we take the measurements.

Axle Type - for square tapers, the ISO introduced a standard for European makers in the early 90s, JIS then did the same in Asia. Before then it was not so simple, and although there is a degree of interchangeability, the best way to make sure you have the right axle is to stick to the same brand from the same era, ideally the proprietary model.

Axle Length (D) - your crankset dictates the axle length you need and the recommendation should be used to avoid issues with chainline. If you're replacing an axle that works perfectly then this can be matched, otherwise you'll need to check the manufacturers spec, a good resource for older bikes is Velobase.

Centre (B) - measured from the outside of the 'shoulders' of the bearing races, as seen in the diagram.

Drive Side (C) - the right side (with any logos etc on the axle facing you), your right crank and chainrings will mount to this side.

Non-Drive Side (A) - the left side, where the left crank arm will be mounted.

Shell Width - the width of the bottom bracket shell the axle was designed to fit, measured at its widest point.

The best…
5120x2160! Did you read the 2160 vertical!? Yea I can’t stress that enough. Gosh I find it so frustrating there arnt more options in this space. Here is the deal, if you have multiple monitor setup (and you should if you have a work station) you likely will have a couple of 4k monitors kicking around. Now these 4k monitors are staples, and they all have 2160 vertical. If you have 1140 vertical like almost ALL ultra wide monitors do then there will be this annoying stepping with your mouse when you go from one screen to the next. It drives me nuts that the standard for these ultra wides does this. If you don’t have the same resolution vertical from one screen to the next then you won’t have a seamless transition from one screen to the next. It’s just the facts. This dell is one of the only curved ultra wide monitors with 2160 vertical resolution. It runs at 120 hertz which also believe it or not makes it one of the only 5120x2160 resolution monitors on the market to do that. I’m sure you can tell by my writing I have owned a lot of high quality monitors in my time and this one for me is by far the best. I’m switching from a none curved ultra wide 32” LG that runs at 60hrtz. Needless to say this is way better, and sadly there was like this burn in that occurred on my LG that would eventually go away but stick around for the better part of a day. This ultimately put me back in the market looking for a replacement. Point being, now I only buy dell monitors. I’ve never had issues with them , they have great color reproduction, pretty affordable (as of now), basically super reliable all around. Obviously I’m not thrilled about the lack of options for folks that have real work to do on there pcs. All this gamer b.s. in the marketplace, it’s all junk as far as I’m concerned. So if you actually have productive things to do on your pc then you can’t do much better then this monitor, I highly recommend. My only gripe is I wanted a smaller version of this maybe a 32” or 36”, it simply doesn’t exist on the market as of now. However, this works for me, the curved surface buys me back a little desk relestate, and it’s something I really missed with my previous monitor. Side note, I definitely recommend monitor arms for all your monitors. I bought one for the larger center monitor (this one) and it works great. Just be sure you buy one that has a high weight capacity, ideally 44lbs or more. This monitor given its size is 42lbs I believe (although honestly it doesn’t feel nearly that heavy). So just be prepared for that. Hope this is helpful, and I hope the manufacturers wake up one day and realize this screen resolution isn’t a nice to have, it’s a must for a lot of people.

Perfect “Command Center” Monitor for Mac Studio – Worth the Money
Title: Perfect “Command Center” Monitor for Mac Studio – Worth the Money I’m using this Dell U4025QW with a Mac Studio M2 Max, and it’s exactly what I wanted: a huge, sharp, curved workspace that also handles games really well. The 40” 5K2K screen lets me keep Docs, email, browser, and gradebook all open at once without feeling cramped, and the curve makes it comfortable to use for long stretches. Text is clear, colors look great out of the box, and bumping it up to 120 Hz makes macOS feel noticeably smoother. The Thunderbolt/USB-C hub is a big bonus – one cable to the Mac, and everything else (keyboard, mouse, etc.) can live on the back of the monitor, so the desk stays clean. It’s not cheap, but if you live in documents all day and also want your games to look and run smoothly, this is a fantastic “do it all” monitor and I have zero regrets about the purchase.

The best business monitor
I have used many of the monitors in the Dell UltraSharp line and thought that my previous monitor, the U4021QW was the apex of Business monitors. The U4025QW improves on it in small but meaningful ways. Looking at the monitor, you can't visually tell the difference at first glance. To me the ultra-wide curved monitor format is preferrable to dual monitors. The 5120 x 2160 / 21:9 screen ratio gives the business user more vertical space while not sacrificing the horizontal space. Many ultrawide monitors give you the width of 5120 but stick you with 1440 vertically. That resolution always felt cramped to me. This connectivity on this monitor far exceeds its predecessor. It is upgraded from Thunderbolt 3 to Thunderbolt 4, adds 2 usb-c ports and one USB-A, giving a total of 5 USB-A and 5 USB-C. This allowed me to replace my old desktop dock and go with a direct connection to the monitor for everything. When reading about the monitor, I thought the drop-down ports were a bit gimmicky, but it is a big improvement over the location on the previous model. This is very accessible and helps with wireless devices whose signal degrades by being placed behind the monitor. The monitor is pricey, but I think it is worth it if you are on your computer all day every day. As on co-worker once said, the monitor is the part of the computer that we use 100% of the time we interact with it.

Extremely sturdy
Color: Black-Mount
I purchased this heavy-duty dual gaming monitor arm holder as a birthday gift for my husband to mount his curved gaming screens, and it completely transformed his setup. It feels extremely sturdy and well-built, easily supporting both monitors without any wobble or instability. The adjustability is excellent. He can tilt, swivel, and reposition each screen with ease, which makes it perfect for both gaming and everyday computer use. It also helps clear up a lot of desk space, giving his setup a much cleaner and more organized look. Installation was straightforward, and the mounting hardware felt solid and secure. Once everything was set up, the arms moved smoothly but stayed firmly in place when adjusted. He absolutely loved it and immediately noticed how much more comfortable and immersive his gaming experience became. Overall, this is a high-quality, durable monitor mount that made a perfect upgrade for his gaming station and a great birthday gift.

The Product is Great - The Customer Service is Even Better
Color: Black-Mount
I want to preface by saying I have never written a review for a product on Amazon. Having said that I felt compelled to review this particular product after an incredibly positive interaction I had with AVLT. I purchased this set of monitor arms due to the fact that my desk is relatively small, as is the space I have to work with while at my computer. I currently have two monitors, a 34" Samsung 2K monitor for gaming, and a 32" Samsung 1080p monitor. After purchasing this product and assembling it, I realized my 2nd monitor (32") was a few years too old and the bracket adapter for the monitor arm didn't fit. That was fine, as at least I had some extra space to work with until I got myself a new monitor to use with the other monitor arm. Fast forward several months and I finally had the monitor I needed - only to find out that I had lost or misplaced the additional bracket. So now I had 3 monitors and even less space to work with. After a lengthy search for a sufficient replacement part, I finally reached out to AVLT in desperation regarding this missing bracket. My query was answered by an employee named "George" the very same day, and within 48 hours I was able to secure the replacement bracket which is currently en route to my house from Taiwan. Alongside the headache of not being able to properly mount the monitors I had on hand, I start working from home this coming week, and my wife is currently 33 weeks pregnant. Needless to say, the ease with which I was able to negotiate this minor, yet irritating problem I was dealing with has helped me more than any Amazon review can ever repay. The help I received from George was simply outstanding, and I hope he receives the recognition he deserves from the company he works for. Sometimes even little things like a quick response can help people more than you realize. Thank you, George and AVLT! Oh, and the monitor arms are great. They're sturdy (metal not plastic), firmly clamp to my desk, and are easily adjustable. As stated in some previous reviews, there is a bit of clearance needed behind your desk in order for these monitor arms to move about, but that's a minor inconvenience at worst. I recommend them, and the fact that the company is there to help should anything go awry is extremely helpful in a world where the emphasis on this seems to be fading away. If I ever need a product similar to this one, or know anyone who does, I will recommend AVLT products specifically based on the customer service I received (the product is awesome too). Thanks again, George! - Joel
