FRAME AND FEATURES
The SCOR 4060 Z ST XT is the top-tier trail eBike in SCOR’s range, with a 140mm travel rear end and 150mm travel fork rolling on a pair of 29-inch wheels. The 4060 is powered by the Shimano EP8 drive unit with a 720Wh battery. Out back the 140mm of travel is controlled by SCOR’s lower-link driven “Instant Center Linkage” suspension system, a dual-link design that has some tuned kinematics to give efficient pedaling characteristics and plentiful “pop” on the descents.
SCOR offers their 4060 Z platform exclusively in carbon fiber. The frame has full internal routing for the cables with ports at the side of the head tube. There is a bottle cage mount and tool mount inside the front triangle; the signature ribbed SCOR chainstay guard; and a generous downtube guard to protect the motor and a removable battery cover. The frame uses a SRAM UDH for easy replacements or if you’d like to upgrade to the new SRAM AXS T-Type derailleur. On the lower link, there is a flip chip to allow for the switch from the ST to LT mode in combination with a different shock. The headset is an angle adjust model, giving a “slack” or “steep” head tube angle by rotating the cups in the frame.
DRIVE UNIT AND ELECTRONICS
The SCOR adds to the tally of Shimano STEPS EP8 motors, as featured on seven of our 13 bikes in this year’s eMTB shootout. The EP8 delivers 85Nm of torque for its 5.7lb (2.6kg) weight and is spec’d frequently as a safe bet for good performance. The battery is a removable integrated Darfon unit with a 720Wh capacity, with full Shimano support to facilitate easier service if an issue is encountered. It uses an Allen key bolt to secure the battery in place within the downtube to prevent rattling. The SCOR uses the EM800 display and EM-800L assist switch to show the key information and offer control of the different functions and modes. The modes are ECO, TRAIL and BOOST, and the Shimano E-TUBE PROJECT app allows the user to tweak two customizable profiles to obtain the feel and assistance levels desired.
The geometry of the SCOR 4060 Z ST points towards its fun-having intentions, with a compact wheelbase given its comfortable cockpit size that keeps the rider in a commanding position but allows for quick changes of direction and easy manuals and hops.
The SCOR 4060 Z ST is given geometry for all-round fun, with a focus on a short rear end and low standover to encourage playful antics on the trail. There’s a size range of Small to Extra Large, with low seat tubes and stack heights to allow each rider to choose between multiple sizes. In the slack headset position, the size large tested with a 440mm seat tube length has a reach of 485mm and stack height of 625mm. Shared across all sizes are a 64.5-degree head tube angle, 78.5-degree seat tube angle, 435mm chainstay length and 29mm bottom bracket drop. The large has a wheelbase of 1,235mm, shortest in this year’s shootout.
SCOR currently offers their 4060 Z ST in a choice of two different specs – the $7,499 SLX build, or the $9,499 XT build, which we reviewed. The XT build features a selection of components that wouldn’t be out of place on a hard hitting enduro bike, signifying the “party” intentions SCOR has for their trail eMTB. Leading the charge is a Fox 38E Factory fork with 150mm travel, which is paired to a Float X Factory rear shock. As the XT in the name suggests, there’s a full Shimano Deore XT groupset, with 4-pot XT M8120 brakes stopping on 203mm rotors, a 12spd drivetrain with 10-51t cassette, and a 165mm XT M8150 crankset. The cockpit is a 35mm long Burgtec Enduro MK3 stem and SCOR 20mm rise carbon bar, with 31.8mm diameter. A BikeYoke Divine dropper, with 125mm – 185mm drop depending on the frame size, is topped with a Fizik Terra Alpaca saddle.
Rounding out the specs is a DT Swiss H1900 SPLINE alloy wheelset, which is usually wrapped in a Maxxis Assegai EXO+ and Dissector DD tire combo, but was fitted with our control tire spec for this shootout. Thanks to Schwalbe, for the 5th year running we’ll be running their trusty tires on all of the bikes in the shootout to provide a fairer comparison from bike to bike. We have the Magic Mary Soft Super Gravity in the front and Big Betty Soft Super Gravity in the rear on all bikes in this year’s group test.
