- 4-Axis alloy forged core
- Ritchey Matrix structural carbon exoskeleton to enhance stiffness by 12% over the standard 4-Axis
- Taper head titanium bolts
4-Axis stem technology is combined with Matrix carbon alloy - the result is Ritchey's latest revolution in stem design. It has a 3D-Net forged 2014 alloy inner form, which is then mated with a carbon shell. The result is exceptional toughness and raw strength, which is exactly what you want in a stem. Start with the stress-managing forged faceplate, add in precise bolt spacing, and note the angled steer tube slot - all these things make the Ritchey 4-Axis stem stand out. The Ritchey
WCS 4-Axis is a constant standard in stiff, lightweight stem
design. The WCS Carbon 4-Axis has 3 times the strength of pure alloy. It employs bias cut slots for safer interfacing with carbon steerer tubes. The 4-axis style clamp can therefore be said to be carbon handlebar
friendly. To reduce weight, it uses titanium bolts. Look at this number: 121g (in the 110mm/31.8 sizing). The 4-Axis stem has in effect changed stem design forever.
