Scott today pulled the curtains back on a wholly redesigned Addict CX carbon cyclocross racer. Despite the addition of thru-axles and disc brakes front and rear, claimed frame weight has dropped to an astonishing 890g for a medium size. Scott says the new Addict CX is also stiffer down below and more comfortable up top. Now let's just hope it gets here in time for 'cross season.
Scott Addict CX key features:
890g/360g claimed frame/fork weight (medium)
61.5 percent claimed improvement in comfort
24 percent claimed increased bottom bracket stiffness
32 percent claimed increased head tube stiffness
100x12mm front, 142x12mm rear thru-axles
Front and rear disc brakes (140 or 160mm rotors, post mount or Shimano flat mount)
Optional lightweight single-ring chain guide
1 1/8-to-1 1/2in tapered head tube with integrated bearings
PF86 bottom bracket
Convertible cable routing
Big improvements all around
The current Scott Addict CX is no slouch come race day but Scott says it wanted to widen the bike’s appeal while also making it faster, too.
New tube shapes, hollow carbon dropouts, and a refined layup schedule have supposedly dropped 60g from the original, bringing the claimed weight down to just 890g for a medium size (plus 360g for the all-new matching fork). Meanwhile, a partially flattened top tube, offset seatstays, and a slimmed-down 27.2mm seatpost are said to boost rider comfort by more than 60 percent (based on deflection at the saddle under load). Scott also claims concurrent gains in head tube and drivetrain stiffness thanks to the newly tapered 1 1/8-to-1 1/2in front end and new PF86 bottom bracket shell, which not only allows for a much bigger down tube but also spreads the chainstays far enough apart that they no longer need to be pinched down for tyre clearance.
The new bike is supposedly not only stiffer and lighter but more comfortable, too
Naturally, Scott has graced its latest carbon 'cross racer with front and rear disc brakes and thru-axles at both ends. Riders will be able to use either 140mm or 160mm-diameter rotors, as well as either Shimano's upcoming Flat Mount brake calipers or current post mount ones with an adapter. The rear end uses the conventional 142x12mm axle dimensions while the front goes with the new 100x12mm standard.
Tyre clearance is greatly increased all around with the new bike said to accommodate tyres up to 40mm wide. The tops of the chainstays are even shaped so as to help cleave caked-on mud from the sides of the tyre, and there's not even the hint of a shelf behind the bottom bracket shell on which debris can accumulate.
Disc brakes and thru-axles are featured at both ends
Cable routing is fully internal and convertible via a series of interchangeable 'chips' at the head tube and rear dropout. Mechanical and electronic drivetrains are easily accommodated, and there's even an optional port for an internally routed dropper seatpost should you want to use one.
One particularly clever feature is the front derailleur tab. Not only is it (and the mini-chain keeper below it) removable when using a 1x drivetrain but the mounting holes can instead be used for a custom mini-chain guide for what should be an ultra-reliable single-chainring setup. That chainguide is even ultra light at just 22g (claimed).
The removable front derailleur tab and bolt-on chainguide are very slick
