The Flow EX3 craves high speeds and the most demanding trails and courses. With a proven pedigree in Enduro World Series and World Cup DH races, this is the most durable, high-performance wheelset available.


The Flow EX3 rim combines the 29mm internal width and durable 6069 aluminum construction of the Flow MK3 with the incredibly strong Tiebeam triple cavity design of the classic Flow EX rim. The result is a rim shape that perfectly balances radial compliance with lateral stiffness and sets the benchmark for durability and impact resistance. The Flow EX3 rim’s Tiebeam inner bridge lets it withstand impacts that would deform most rims to the point of air loss and structural failure. Even if you use a tire insert, huge impacts can cause the sidewall of most rims to fold, causing air loss and eventual failure. But the Tiebeam brace and patented low sidewalls of the Flow EX3 resist this folding, maintaining air pressure and structural integrity better than any other rim.


M-PULSE HUBS


The M-pulse hubs at the heart of Flow MK4 wheels combine an absolutely bombproof magnetic locking engagement with incredibly smooth rolling. Based on the original innovative Project321 engagement system, the speed and durability of this system is unmatched. Unlike weaker pawl and spring designs, the M-pulse features six pawls with Neodymium magnets that offer virtually no resistance when coasting, but lock the pawl teeth into place far more reliably and consistently than springs.


Each detail of the M-pulse hub was engineered to systematically eliminate weaknesses found in other designs. The 17mm axles are made of 7075 aluminum and roll on Enduro brand bearings, including a double-row freehub bearing tested to be far more durable than two individual separate bearings. The entire hub is also shielded, meaning no bearing seal is visible, offering superior protection for all conditions.


With only 1.66°of rotating required for the M-pulse hub to engage, power is always instantaneous. Multiple tooth engagement provides a greater surface area to distribute load to improve both durability and speed. The angle of the pawls was even optimized to distribute stress away from the rotating bearings. Beyond the strength and speed of engagement, M-pulse hubs feature adjustable preload, allowing a tremendous decrease in drag for less resistance and more speed.



  • Low-profile 30mm internal width optimizes tire shape,traction, and control for 2.3-2.6” tires

  • Durable 6069 aluminum with welded joint and reinforced spoke bed

  • BST Asymmetric design combines Stan’s legendary easy tubeless inflation with a stronger, more balanced wheel build

  • New high-end premium M-Pulse hub with 216 points of engagement (1.66º), magnetic-sprung pawls to reduce drag and improve response, Enduro bearings and external preload adjustment. US-made internals in partnership with Project321

  • Matched wheelsets use traditional J-bend lacing and share a single spoke length for easy serviceability

Casio Tough Solar No Lighted dial, Just Date Box
Color: Green, Style: Modern
A picture of how it lights at night would kill all sales if anyone needs a good readable watch in the dark with a lighted dial as the description says. Just the little LCD insert lights up so it shows just the day and seconds. I guess the date of the day can't fit in the little rectangular LCD insert. I collect watches and this Casio Tough Solar is a superb analog dial watch for working with. This one is solar, so the price is good for that feature, as most Casios may be quartz battery types. This one is for an off shore sea worker so it will stand up to the tough work he does. I wore my Casio, a digital solar, for 14 years now and I build, work hard and these watches from Casio can last surprisingly long. Other brand watches would finally give out for one reason or another as a work watch. The price for this one is affordable for a simple but tough watch that will last over a decade, maybe two.

Best Value Field Watch
Color: Green, Style: Modern
I am a deployed military person. I bought an expensive "field watch" for over two hundred dollars. It broke after being dropped once. I ordered this watch as a temporary watch to use until I can get home and get a replacement for the "expensive" watch. I can tell you without a doubt, this is a much better field watch than the 200+ dollar watch. It has a large face that is easy to read on the move. Although the viewing area for the face is large, the watch is surprising light. I wear it while exercising and doing military duties. I recently competed in a 15 mile ruck run and didn't even notice it on. Probably the most comfortable watch I have ever had. The lumination on the hands and numbers is pretty impressive for the price, and is very visible for a few hours. The digital portion gives you options of timer, stop watch, date, other time zone, and alarm. I am far sighted, so the digital window can be hard to read while moving or when using the light. If I have my reading glasses on, there is no issue. For military personnel, the light on the watch only works on the digital display, and therefore gives off very little light while still making the digital time very visible. You can easily maintain light discipline and check the time, timer, or stop watch without creating a glow like other watches do. I usually don't wright reviews, but I love this watch that much. It gives you the best of an analogue and a digital watch in a light, comfortable, dirt cheap package.

The AQS810W (5208 module) series is one of Casio's best, in terms of being durable, reliable and problem-free.
Color: Green, Style: Modern
This is my second AQS810W... my first is about five years old, and it's black with white lettering. The "Tough Solar" and "Illuminator" are long-gone, rinsed away by automotive degreasers and other auto repair chemicals, but I like it better without those pronouncements, anyway. Army Green, in my opinion, is an excellent color on this watch. The fact that this is not at all a glossy watch, but a matte (or semi-gloss?) finish makes the color attractively subtle. I like it even more than the black. Other than the color, though, it's the exact same watch I've been very happy with for the last five years. Easy to setup, rugged and sturdy, just the right size (for me) and an industrial, utilitarian look. This is a very comfortable watch to wear - light in weight, flexible band, no sharp edges or uncomfortable shapes. I spent a few weeks trying to decide what watch I was going to get, and I came to the conclusion that being solar-powered was my highest priority, followed by being quickly readable. Perhaps it is just me, but I can read a analog watch faster than a digital one - just a quick glance. I kept coming back the Casio's AQS810W series, and it came down to the darker, matte-finished colors. Having said all of that, this series of Casio watches is virtually trouble-free. Read the reviews! VERY FEW failures, defects, water intrusions. People who don't like this series of watches either find them incomprehensible to set or are unhappy with the small digital display or the lack of a backlight for the analog dial. The watches themselves are largely bulletproof, possessing anvil-like reliability and durability. They even have a feature that if the watch is dropped or knocked around too hard, and the analog hands get out of sync with the digital display, you can quickly and easily re-sync them. This series is one of Casio's best, in terms of being problem-free. Yes, they have acrylic crystals, not mineral glass, and they do scratch. Simply buff the scratches out, and it is as good as new. Worried about the band breaking or falling apart? On a regular basis, take the watch into the shower and scrub the whole thing with an old toothbrush and some shampoo. Not only will it be clean and look great, but removing the body oils, sweat and salts makes the bands last and last. That's the secret to getting Casio resin bands to live long lives. The analog dial is not lit, but neither is the dial on my Rolex or Omega. Just find a light source to reflect on the hands, and you're in business. Just like we've done for many years. Anyway, you can tell I am a fan. Buy with confidence, but download the pdf version of the Casio 5208 module operating instructions, and it'll be easier to set up the watch if you aren't very tech savvy. If you like the way this series of watches looks, then I'm pretty confident you'll be very happy with your purchase. Have fun!

Great everyday watch
Color: Green, Style: Modern
I still own an older, cheaper Casio from 1994 and it'd been through the wringer. 130' of depth and banging onto a shipwreck couldn't even kill it Paint splashes and scratches to the face have made the dial harder to read but it still works. Even the battery change every 4 years is simple and cheap and in short, I CANNOT KILL THIS FREAKIN' WATCH. While the old watch still works, it's a little dated. Thus I looked into a newer, updated model of Casio watch for the next decade or so. This model caught my eye with a simple analog interface (Hate Digital watches), but still offered features such as an alarm, Stop-Watch, Timer, Alarm and even charged via Solar to eliminate even the battery replacement. I love this new watch. Good looks with a easy to read Analog face in dual colors (White for minutes, blaze orange for hours) and even glows in the dark. The controls are simple enough and I use both the Stopwatch and Timer on a near daily basis. Probably the sole drawback is the size of the digital readout. It could be a little larger, but maybe that's age creeping up on me. Altogether a darn good everyday watch that has decent looks, practicality and should last quite a long time.
