SCOTT Contessa Spark 700 Bike

Our patented Twin Loc technology now offers simultaneous control of rear shock travel and fork lockout. The open position allows full travel, front and rear. One click switches the rear shock to Traction mode, while the fork remains fully active. Click again and rear shock and fork lock at the same time. No other bike in the world offers this user friendly system. Found on the Spark & Genius and Genius LT models. Only available for Nude2 shocks on 2013 or previous year models.

The Spark down tube shock and linkage are clearly asymmetric, when looking from the top of the bike. Carbon fibres achieve their full potential when used in smooth straight lines. Off setting the shock slightly to the left hand side of the bike gives a clean and continuous structure from the down tube through the shock mount to the main pivot.

 

 

 

 

We have adopted the new Metric shock sizing standards with a Trunnion mount. Since the shock body now extends between the two lower mounting bolts, our suspension partners have more design space. This means the shock has more stroke for the same eye to eye length. Stroke on the 165mm eye to eye shock has increased from 38mm to 40/45mm.The Trunnion standard also offers structural gains. The shorter shock enables us to build a very compact frame and shock package, which integrates tightly to the seat tube. We managed to have a very tiny yet stiff linkage-lighter than ever. Thanks to the Trunnion mount construction, stand over height on the new Spark is very low. We are still able to realize a super compact full suspension frame and provide the ability to mount both a small and big water bottle.

The Spark family maintains the 165mm eye-to-eye shock length of the previous Spark 900 (our shortest shock), but realises up to 7mm more shock stroke. All Spark RC and most Spark and Spark Plus bikes utilize the FOX Nude shock, specially made for SCOTT:

-165mm Metric Trunnion shock

-40mm (100mm travel RC Spark line-up) vs. 38mm (old Spark)

-45mm (120mm travel Spark line-up)

By turning the Trunnion shock upside-down, we can fully integrate it into the frame which results in several benefits.Since the Trunnion mount is the same width as the down tube and mainpivot, we can have a very clean frame design in this critical area. The lack of tight transitions and small details allows for an efficient, continuous carbon structure. Carbon material added to reinforce the shock mount also stiffens the connection between the down tube, main pivot and bottom bracket, a key stiffness path.

The flipped shock also lowers the frame’s center of gravity helping to give a more planted feel when riding. Unsprung mass is reduced since it is the lighter part of the shock, connected to the linkage, not the heavier body which must move during an impact – the suspension system can react faster.Our TwinLoc remote cable can be routed cleanly into the down tube.

The Spark carbon linkage is constructed with a compression moulding process. It’s 37g lighter than the aluminium equivalent and half the weight of the previous Spark linkage. Making the link in two pieces means all excess material can be removed from the inside of the linkage,without sacrificing stiffness.

Boost is a hub and drivetrain standard developed by SRAM. Boost is built around a wider rear and front hub and enables stiffer wheels due to a wider spoke bracing angle. Boost 148 rear hubs move each flange of the rear hub three millimeters wider.

Boost is designed as a complete system so drivetrain performance isn’t compromised. Even though Boost pushes the cogs three millimeters outboard, the crankarm Q-Factor remains the same as the Boost system’s crankset utilizes front chainrings that sit a corresponding 3mm outward to ensure the required chainline. Boost cranks can onlybe used when paired with a 148mm hub. On the front the hub spacing is increased by 10mm to 110mm. Increased wheel stiffness and greater clearance for bigger tires are the main advantages of Boost technology. On our bikes, we wanted to go beyond the basics and reap all the benefits of this innovation by optimizing frame design and geometry.The 3 mm outboard chain ring adds clearance in the chain stay area that allows a substantial increase of the chain stay tube cross-section. Correspondingly,the stiffness in this part of the frame improves. Also, with a wider range of positions for the rear wheel, the frame geometry can be adjusted. We can shorten the chainstays for more agile handling.

With the proper selection of materials, eighty percent of the work to create a frame is done. But the remaining twenty percent requires most of our efforts. For this reason, our choice of the most advanced carbon fibers in the market is followed by intensive use of specific tools, like FEA(finite element analysis) software, to map out the carbon lay-up.

With FEA software, we can simulate different forces on a virtual model of the frame and adjust the frame construction accordingly. FEA software enables us to create complete virtual prototypes incorporating all the physical phenomena that exist in real-world environments.

With our Evo-Lap technology we model the frame to optimize the surfacearea, simulate tube structures with different ply orientations, observethe results of using diff erent configurations, and test the stress distribution in different areas of the frame. Thanks to this extensive computer modeling, we’ve optimized the carbon layers in all the parts of our frame. When the parts were bonded together in the first prototypes, the result was a super light and compact frame without a sacrifice in the stiffness, comfort or impact resistance. The entire range benefitted from our EvoLap technology.

On the Scale, Spark and Genius we’ve redesigned all the parts that can give us significant benefits in terms of performance and functionality. On the previous model the support of the dropout was a bulky additional part molded to the carbon chain stay. The new dropouts are designed to be integrated on the thru-axle system thanks to a hollow tubular design that allows a simple and light weight structure. Available for SRAM and Shimano DM derailleurs, this dropout increases the stiffnessand avoids damage to the frame in case of impacts on the rear derailleur.

On the new Scale and Spark, to provide a clean look and a functional solution for all the different control cable standards on the market, cable routing is fully internal and designed for full length cable housing. Routing the cables internally omits bulky external hardware and looks cleaner. The cables can endure a longer lifetime as they are protected within the frame. The entry points are machined alloy removable inserts that come along with the frame and can be chosen according to the setup of the bike. Assembling an electronic group or a dropper post will not be a problem and the look will always be clean-cut.

Velo Tout Terrain review

With a weight of 2010gr with the shock and hardware, the new Spark frame represent the benchmark for light weight. I was surprised by the ergonomics of the Twinloc lever positioning just below the h'bar thanks to the absence of the front derailleur. Basically, I guess it is impossible to find a better place for this. The efficency of the twinloc helps the bike to be a war machine on the smooth climbs. The front end is precise, the whole bike is precise to ride but it always offers a margin of error that for me was quite unexpected despite the carbon wheels and carbon frame. At this point I'm feeling free to look for some different lines just to have fun. On mixed terrain like the one of the XC world cup in Lenzerheide, switching to traction mode, the spark become a small XC bomb with enough traction on the rear wheel to ride on stones and roots without loosing grip.

Canadian Cycling - review

Scott has done a great job with the Spark 120mm. The company has made a true multi-purpose, Swiss Army knife of a bike. The 2017 Spark has seen a number of refinements. One is the 1-by specific frame. by eliminating the need for a front-derailleur mount, and second chan ring, Scott can fine-tune the frame and offer a wider BB stance, improvin g balanceand handling as well as saving weight. (...)

When ascending steep climbs, I could use the Twinlock remote to firm up both front and rear suspension giving me great pedalling efficency.

Then when things got technical, I could simply flip the switch and have some travel to soak up bumps and maintain traction Eeven with the new slackened geometry I found it easy to keep the front wheel planted and pointed where I wanted to go. The slackened head-tube angle also really helps to give you confidence steering when things get steep.

As nice as the scenery and trails were, it was the the bike that impressed my the most. It didn't seem heavy or cumbersome on the climbs .On the descents it didn't feel light and bouce away from my line. The Spark 120mm might not be the the fastest on a XC course or the first to the bottom on a DH track but it is certenly the bike you can be confident on doing both. 

MTBR review - XC Bike of the Year

Scott's fully revised Spark XC rig ticks all the right boxes. Mtbr’s 2016 cross-country bike of the year is really two bikes. Or three if you count the plus version. Or five if you account for 27.5 and 29er offerings. But for the purposes of this award, focus is on the new 120mm Scott Spark with 29er wheels. That’s because for a modern cross-country bike, we see it as the near perfect combination of uphill efficiency and downhill capability. Granted if your name is Nino Schurter or Jenny Rissveds, you’re going to opt for the racier RC model (as in “racing concept”). That bike has 20mm less suspension, a slightly steeper headtube angle, and two Olympic gold medals to its name. But most of us aren’t training for Tokyo 2020, and instead are looking for a bike with well-balanced talent. And that is just what the latest iteration of Scott’s XC platform is. (...)
