With the Spark 950, the latest Spark suspension technology is fully expressed in an affordable, all-alloy package. Made with custom butted, hydroformed 6011 alloy SL frame tubes, this bike uses the same suspension designs as its carbon cousins. FOX suspension, a Shimano drivetrain and a full suite of Syncros parts, round out this capable build.
- Spark Alloy SL 6011 Frame
- Shimano 2x10 Drive Train
- FOX 34 Float Performance 120mm
- FOX NUDE 120mm Twinloc
- Shimano M506 Disc Brakes
- Syncros Components
- Syncros 2.0 120 Seatpost
Improved roll-over is the most noticeable attribute when it comes to 29” wheels. The big wheels are great for rolling over nasty roots and rocky sections, essentially making it easier to ride these conditions. Improved traction is also a key factor with the increased wheel diameter compared to 26” wheels as tire contact to the ground is larger.
TWINLOC LEVER SYSTEM
TwinLoc Lever System 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 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,them 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.
