Pressure Recommendations (40mm)
| Rider Weight | Dry | Mixed | Wet |
|---|---|---|---|
| 140-160 lbs | 35-39 psi | 32-36 psi | 30-34 psi |
| 160-180 lbs | 38-42 psi | 35-39 psi | 33-37 psi |
| 180-200 lbs | 41-45 psi | 38-42 psi | 36-40 psi |
| 200+ lbs | 44-48 psi | 41-45 psi | 39-43 psi |
All pressures assume tubeless setup with 21-25mm internal width rims. Wider rims allow 2-3 PSI lower. Add 5-8 psi for tubes. Pressures are starting points — fine-tune during training rides on similar surfaces.
Race-Day Tire Setup
Tubeless
Recommended
Tubeless provides better comfort and puncture protection, even on smoother courses.
Sealant
60-90ml
Standard amount should work fine for this course.
Spare Strategy
Carry a tube and tire plugs. Standard repair kit should handle most issues.
Pre-Race Break-In
Mount tires 2-3 days before race day. Ride at least 30 minutes to seat the bead, check for sealant leaks, and verify tire pressure holds overnight.
