Bicicletta SCOTT Spark RC 900 World Cup

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.

 

 

 

 

Working together with DT Swiss, we completely revisited the shape of the thru-axle lever to make it more ergonomic and to perfectly fit to ourframe. Additionally we introduce a new multifunctional tool integrated on the inner part of the thru-axle itself. This 25T torx wrench is easy to reach and ready to be used for quick adjustments on the trails.

Our integrated chain guide was developed in collaboration with the SCOTT SRAM MTB Racing Team. 

The idea behind was to create a reliable component that helps to avoid dropping chains but that was light, versatile and integrated in the design of the frame. The new Spark chain guide weighs just 23 grams and is easy to assemble thanks to the smart assembly system and can accommodate chain rings from 30 to 36 teeth.

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.

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.

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.

Con TwinLoc un ciclista può effettivamente controllare tutto il telaio, la forcella e l’ammortizzatore, come un unico elemento. Perché è importante? Una bici con escursione delle sospensioni di 150 mm, correttamente impostata, ha più sag di una con 130 mm. È l’escursione addizionale a renderla più divertente da guidare e più abile nelle discese, il sag maggiore ha però un effetto negativo sulla geometria della bici e sulle prestazioni in salita. Qui è dove TwinLoc entra in gioco.

TwinLoc contribuisce a gestire l’effetto di sag in modi svariati. La maggioranza dei sistemi non fa altro che aumentare la compressione a bassa velocità, nello sforzo di guadagnare efficienza di pedalata. Il TwinLoc invece ci permette, non solo di cambiare lo smorzamento della compressione, ma anche di cambiare la curva di progressione della molla, alterando dinamicamente la geometria della bici. In modalità Trail, l’ammortizzatore non è solo più duro, ma ha anche dinamicamente meno corsa. La bici rimane più alta, mantiene un angolo sella più verticale per le salite e diventa più agile. Offriamo anche una terza modalità, in lockout integrale, per poter salire nella maniera più efficiente possibile.

Queste impostazioni uniche ottimizzano la geometria di salita anche nelle bici con le escursioni più grandi. Possiamo eliminare “l’effetto grande escursione”, che toglie efficienza alla tua pedalata, ma senza togliere tutto il divertimento dell’escursione di 150 mm, quando scendi a valle. Da un’impostazione da gara, a un giretto breve in pausa, a un percorso trail dopo lavoro: avere la possibilità di cambiare da modalità a modalità a seconda del percorso affrontato con una semplice leva è garanzia di velocità, performance e sfrenato divertimento.
