The Continental Terra Trail 650b is the gravel tire with pronounced tread in the Terra range, designed for cyclists seeking bite, versatility and maximum protection on varied terrain. With its ProTection construction, BlackChili compound and e-bike e25 certification, it combines off-road performance and reliability over long distances.

Technical Summary

The Terra Trail 650b x 40 is positioned as the most aggressive model in the Terra series, between the speed-oriented Terra Speed and the future Terra Adventure dedicated to extreme off-road. Manufactured in Germany according to Continental standards, this Tubeless Ready tire features a 180 TPI carcass with reinforced ProTection (woven anti-puncture belt + protected sidewalls) and the BlackChili compound based on nanometric carbon particles, guaranteeing an optimal compromise between grip and low rolling resistance. Certified e-bike e25, it supports the increased stresses of electrically assisted bikes up to 25 km/h. Its 40-584 profile (650B x 40 mm) offers cushioning comfort and stability on broken trails.

Technical Highlights

• Reinforced tread blocks: Tight center knobs for smooth rolling on pavement and compacted trails, wide and tall shoulders with aggressive profile for cornering grip and on loose terrain (gravel, dirt, grass).
• ProTection Technology: Integrated woven anti-puncture layer (tread + sidewalls) that reduces puncture risks by 30% compared to previous DuraSkin protections, while remaining 25% lighter. High resistance to impacts and sharp debris.
• BlackChili Compound: Exclusive Continental compound manufactured in Germany, combining synthetic and natural rubbers with optimized carbon particles. Offers exceptional grip in dry or wet conditions and increased longevity.
• Tubeless Ready: Optimized Revolution bead for simple and quick tubeless mounting. Compatible with Continental RevoSealant. Allows riding at reduced pressure (35-45 PSI tubeless) for more comfort and grip, while limiting puncture risks.
• E-bike e25 certification: Reinforced structure to support the additional forces generated by electric assistance up to 25 km/h, with increased resistance to premature wear.
• German manufacturing: Handcrafted in Germany, guarantee of rigorous quality control and durability.
