Open UP SRAM Force AXS Gravel Bike When the Open U.P first came onto the scene it was loved for its capability to fit either mountain bike or road wheels with a range of tyre sizes, meaning that your rides are no longer limited to surface type. In its 3rd generation the love for the U.P is exactly the same however, now, the frameset is; lighter, nimbler and more ready for adventure than ever before. Open call it "TRCinTRP". No, it's not some fancy tech name that CEO's took hours thinking up, it's a play on words standing for "The Right Carbon in The Right Place". In Lamen's terms, it means that high modulus carbon is not just slapped across the whole frameset, instead, the modulus of the carbon is correct for the exact area in which it is placed ensuring the frame is responsive, lightweight and able to cope with whatever the road or trail can throw at it. Here, at the TriStore, we have finished off one of our best selling framesets with a groupset that is made specifically designed for adventure riding. The SRAM AXS Eagle groupset features a 1x chainring and a wide rear cassette, removing the hassle of front derailleur shifting and ensuring you have plenty of gear range to ride up the hills and race down them.

In store stock is limited- this is easily order able- lead time is usually 1 week U.P.P.E.R. Frameset Information Open Cycles builds light and strong. And they knew they could make their UP frameset even lighter. That meant they had to build one. The result is the UPPER. Think same geometry, same ride qualities, just lighter. Lighter means a few things here. First, they built their own fork, the Open U-Turn. Second, more complex carbon-fiber lay-up with more expensive carbon plies. Third is flat mount brakes. In all, the bike fits, the same, rides the same, but is trimmed of the precious little fat that Open had actually left on the table. Flat mount disc brake calipers are the rage. They allow for lighter calipers to be fixed to the frame, but they’re only lighter if the adapters that are usually necessary with flat mount brakes are removed. Open designed their mounts so adapters are unnecessary. The result is an even lighter build and no choice in rotor sizing. It’s 160mm in front, 140mm in back, unless you want to add those adapters back on. A side effect is the bolts go through the fork and frame. If you’re reading about the UPPER, we assume you know a bit about the UP: a single bike that can race and ride on road and off and handle cyclocross in style. It has the manners to feel comfortable at low speeds and high, and handle both straight lines and tight turns with aplomb. They call it “gravel plus.” This bike is designed to accept both 700c and 650b wheels. You can run up to a 40mm wide 700c tire and up to a 2.1” wide 650b (aka 27.5”) tire. That 40mm ‘cross tire actually results in a 8mm greater diameter than the seemingly big 2.1” 650b. While the flexibility is nice, it was to improve performance in all conditions. Part of the performance issue was keeping chainstays as short as possible. In this case, 420mm. It’s a length is rather short for this application, and it’s a performance benefit. Shorter wheelbase, lighter frame, snappier responses to power spikes. You’ll notice that the right chainstay is dropped. This is to fit both the tires and the chainrings without either rubbing the frame. The gearing is more flexible than tire choices. You can run a single or double ring, with electronic, mechanical, or hydraulic shifting. The inner ring max is 36t, the outer ring max is 50t. When you’re running single chainrings, you can go up to a 46t single if it’s an offset style like SRAM’s, or a 50t if you’re using a flat style ring. Cables, btw, run internally regardless of the style. The battery, if you choose Shimano Di2, sits inside the post. The single stop on the side of the head tube is small, light, clean, and leads to a system that routes easily and saves weight. They call it MultiStop. The bottom bracket utilizes the BB386EVO standard. It’s wide, 86.5mm, and large diameter, 42mm, which is a big easel on which to design the points at which the downtube, stays, and seat tube join. Most cranks will fit. As is designer Gerard Vroomen’s want, the seat angle is 73-degrees. This is for a simple reason. It results in a lighter system because you can use a zero-setback seatpost. Lighter overall system weight, and zero effect on performance. The seatpost also helps strengthen the frame-a too-short post leaves the seat tube unsupported. To ensure the proper length, there’s a pilot hole in the seat tube. So long as the post can be seen (and it’s precise enough that it doesn’t let water in), you’re good. The shaping is almost square at the bottom, and it tapers to a round 27.2mm size at the top. Better for a light, compliant, round post. The post is at the top of the seat stays, which themselves are super-thin, and flattened for vertical flex and torsional stiffness. The chainstays are as well, though it’s much harder to see. The downtube has been designed for torsional stiffness. High-modulus carbon on the sides, and lower-modulus in the middle. Likewise, the top and downtubes are as widely-spaced as possible to improve torsional strength for the fork. This is why the top of the headset is flush with the top tube. Internally, The U.P. runs a tapered 1 1/8” to 1 1/2” steerer, also for rigidity. The fork, also set up for wide tires, same widths as the rear end, includes an superlight 12mm thru-axle from Carbon-Ti that tightens via a 5mm hex head key. The rear wheel attaches to the frame via a 142mm thru-axle. They figured out how to save weight here as well. The axle threads through the derailleur hanger and locks it to the frame. Simple, too. They recommend they send the Carbon-Ti thru-axle, but others work as well. The brake mounts are on the chainstay to allow the seat stay to flex more. The frame comes with the fork, headset, seat tube collar, thru-axles, two derailleur hangers (one on the frame, one spare), removable front derailleur hanger, cover bolts for derailleur hanger studs, MultiStops for cable routing, chainstay cable exit stop, bottom bracket guide, cab
Frameset only This frame does not include seatpost, stem, bars, bottom bracket FAST, FUN, FREEDOM The first U.P. combined road bike speed plus go-anywhere capabilities to start a whole new category. Now original U.P. features such as dual wheel size compatibility and a dropped chainstay are the standard for performance gravel bikes. The third generation U.P. & U.P.P.E.R. frames are lighter, nimbler and more fun than ever. They also still pass our ultimate test: We only offer frames we want to ride ourselves. And because we’re “working hard to stay small”, you always speak directly with the people who developed the bikes.
Please note that all bikes are made to order. Build is personalized. Framesets are $3200 and is the frame, fork and headset. Please give us a call if you are interested. These are the colorways the Open Up is available in. This build is for suggestions and can be built WHAT IS THE U.P.(P.E.R.)? With road tires, it is a very fast road bike With big road/cross/gravel tires (32-40mm), it’s a go-anywhere bike perfect for mixed surface rides and most gravel routes With 650b mountain bike tires, it's unstoppable on very tough terrain yet much faster on pavement than you'd expect thanks to the road position So the position lets you get out of town and reach the gravel/dirt/trails quickly (unlike a mountain bike). Space for big tires lets you tackle any route (unlike a road bike). And you can do that with one type of tire for everything or finetune your ride with multiple wheelsets or tires. This is a custom spec- all other OPEN Cycles are available to order and build- please contact us and we can help build your dream bike!
