OPEN U.P. Frameset Orange

Season:2017

Brand:OPEN

Code:OPENUPXO

Introduction:

U.P. (Unbeaten Path) combines a performance-oriented cross/road geometry & parts with clearance for mountain bike tyres. So you can ride anywhere, and ride fast.

Get out of town on asphalt, hit the gravel roads or switch to singletrack. The geometry gets you there fast; the big tires make you unstoppable.

 

 

Tyre clearance:

The U.P. fits mountain bike tyres up to 2.1” wide. But you can also fit a 40mm cross tire, or a 28mm road tire, or anything else in-between.

 

One of the reasons we designed for the U.P. to take 650b and not 29er tires. They would require very long chainstays, while the U.P. now sports a very short 420mm rear end. Most gravel and cross bikes have longer chainstays than that yet they can't fit anywhere near the same size of tire.

 

 

Crank clearance:

Behind the bottom bracket, the chainrings, frame and tire all fight for space. And with the need to fit big mountain bike tires and narrow Q-factor cross/road cranks & chainrings, the U.P. presents the toughest possible packaging problem.

Dropping the right chainstay moves it out of this crowded area, allowing it to be wider and therefore stiffer (a huge effect; with the same amount of material, twice the width will give you eight times the stiffness!).

 

 

TRCinTRS technology:

“100% hi-modulus carbon”, “aero-space grade”, etc. Useless – and hopefully false (we’ll get to that) – claims meant to impress you.

It’s not about high- or low-modulus, it’s about the right carbon in the right spot. And because the bike industry loves techie-sounding abbreviations, we’ll humour them and call it TRCinTRS.

Fact: stiffer carbon is more brittle. Strategically placed ultra-high-modulus carbon is a good idea. Making the whole headtube out of it when you have big impact loads is not!

The best lay-up is not 100% of one modulus; it’s a blend. We use the highest modulus (stiffest) carbon of any bike manufacturer where we can, and tougher grades of carbon where we must. That’s how our frames are both light and durable.

 

 

Wire-stays:

The rear triangle has to provide lateral stiffness for an efficient drive train, but vertical compliance for better comfort. The U.P. features chainstays and seatstays that are extremely thin vertically to provide that compliance, while their lateral width and layup ensure rock-solid propulsion. Truly the best of both worlds.

 

 

Flat-out downtube:

The downtube is the key for stiffness, connecting the steering center of your frame with the drivetrain. The flat-out downtube’s characteristically flat outside faces allow us to strategically place strips of ultra-high modulus carbon far away from the center plane. The stiffest carbon exactly where it matters, guaranteed!

 

 

Zero-setback seattube:

With a minimalist 27.2mm diameter we maximise the flex in our seatpost & seat-tube. This is especially a big plus on rough terrain. The seat-tube angle is designed around the use of a straight, zero-setback seatpost rather than a regular seatpost with setback (we’ve never understood those). Zero-setback posts are lighter, saving you another 10-30 grams (every little bit helps and you can then put that saved weight into a 500g saddle like the Brooks!).

 

 

Fully-internal cables/hoses:

External cables & hoses collect dirt, risk getting stuck behind objects (particularly expensive with electronic shifting) and frankly, they are ugly. So the U.P. runs them internally.

With our proven MultiStop design, you can customise the frame for 2x10/11, 1x10/11 and Di2 shifting. Just pick the right insert. In case you run a single chainring, you can also remove the front derailleur hanger to further clean up the frame.

 

 

ThruThread dropouts:

Most thru-axle frames are heavier than quick-release frames. Extra carbon for the dropouts, heavy hangers, and the axle itself. But they are stiffer, So what do you want most? The answer for most people is “both”, and so we introduce the first frames that combine a thru-axle with a lower weight. How?

The ThruThread design uses the same threads that hold the thru-axle to lock the derailleur hanger into the frame. Simple, light, effective.

We didn’t just redesign the dropout, the entire seatstay and chainstay design is optimised with the added stiffness of the thru-axle in mind. For the thru-axle itself, we recommend the stiffest design available, the Syntace X-12, but you are free to use a different 12mm thru-axle if you want.

 

 

Toptube bag mount:

For handy storage of your phone, camera, some tools or food, you can use the toptube bag mounts. It fits the standard toptube bags from for example Dark Speed Works and XLab as well as dedicated ruggedised bags from for example Revelate Designs.

 

 

SafePost Pilot hole:

Seatposts usually indicate a minimum insertion dimension. That keeps the seatPOST safe, but it’s also important that the seatTUBE is supported properly. The minimum insertion for that is indicated by the SafePost Pilot hole.

 

 

Bottom bracket:

The U.P. uses the 386 EVO bottom bracket standard. The wide (86mm) BB shell is perfect to attach the dropped drive-side chainstay to. Furthermore, it fits most of the cranks on the market, from Shimano, Campagnolo and SRAM but also smaller brands like THM, Rotor and RaceFace. 386 EVO even allows for the installation of many mountain bike cranks.

    Super light frame, well thought out design and beautiful orange paint job that attractions attention at every turn. Looking forward to tackling new back trail courses here in Michigan.
