Installation Guide
Adjust the saddle clamps and the saddle rail position so that the tightened bolts sit at 80°–90° to the rails. Installing beyond this angle risks damage.
- Front bolt: Tighten to 3–4 Nm (27–35 lb-in).
- Rear bolt: Tighten to 6 Nm (53 lb-in).
- Weight limit: 90 kg (198 lbs). Always use a torque wrench.
Lightweight by Design
S-PARTS uses mechanical simulation to calculate load distribution, then places material only where the forces are highest and removes it everywhere else. The result is a much lighter part than stock cast aluminum, with strength comparable to forged components.
Precision SLM Titanium 3D Printing
The seat clamp base and saddle clamps are made on industrial SLM (selective laser melting) metal printers using high-purity Grade 5 titanium (Ti-6Al-4V) powder. A 20-micron powder layer gives a fine, smooth surface.
Each part goes through more than ten steps, including stress-relief annealing, hand grinding to remove supports, thread tapping and surface coating, so it fits the frame cleanly.
Colors & Patterns
Patterns are available only for the Complete Kit (1) and the Seat Clamp Base (2). Multi-layer electrolytic anodizing creates saturated, durable color on the titanium surface.
| Variant | Colors | Patterns |

| 1. Complete Kit | Gold, Rainbow, Titanium, Black, Blue, Purple, Green, Candy, Indigo, Copper | Splatter Pop, Neon Splatter, Tiger Green-Gold, Jaguar Green-Gold, Snowstorm, Topographic Glacier |
