3T Bike

Frequently Asked Questions

• How do the Exploro, Racemax, and Ultra models differ, and which 3T bike is best for my riding?

  Exploro is 3T’s aero-gravel pioneer focused on wind-tunnel optimization while accommodating big tires (up to ~61mm) for fast mixed-terrain rides; Racemax is the race-oriented gravel frame optimized for high speed with tire fit around 35–42mm; Ultra is the e-gravel/rough-terrain option with very generous clearance (~55–61mm) and 1x-focused drivetrains for long exploratory rides. Choose Racemax for flat, fast gravel races, Exploro for aero efficiency on mixed routes, and Ultra when you need electric assist and maximum rough-terrain capability.
• How should I approach sizing and fit for 3T road and gravel frames?

  3T frames use road-inspired, responsive geometry so prioritize reach and stack numbers rather than just nominal size; compare each model’s geometry chart to your current bike and consider intended tire size because bigger tires change effective fit and handling. Many 3T models accept 27.2mm round seatposts and offer compatibility with droppers or suspension posts on select frames, so confirm seatpost diameter and max saddle height for the model you’re considering.
• What does 3T’s automated filament-winding construction mean for performance and sustainability?

  3T’s automated filament-winding process uses continuous carbon fibers (including zero-degree fibers in key areas) and automated layup to produce consistent tube shapes with high stiffness-to-weight and reduced material waste. The result is frames that feel stiff and efficient for power transfer while maintaining a relatively light mass and lower manufacturing emissions compared with more wasteful layup methods.
• What tire clearance and drivetrain options should I expect across the 3T lineup?

  Tire clearance varies by model: Exploro up to about 61mm, Racemax around 35–42mm, Extrema roughly 47–57mm, Ultra around 55–61mm, and Strada road-oriented frames typically accommodate ~30–34mm+. Larger clearances let you run lower pressures for traction and comfort on rough surfaces, while narrower clearances favor rolling speed and aerodynamics on smoother roads.
• Are 3T frames compatible with modern 1x drivetrains, droppers, and disc brake standards?

  Yes, many 3T gravel and adventure frames are designed for 1x drivetrains out of the box while retaining 2x compatibility on certain models, and frames use thru-axle dropouts for modern wheel stiffness and alignment. Select models accept 27.2mm round seatposts and droppers (check the model spec for Extrema and others), and 3T frames are built around contemporary disc-brake standards, commonly accommodating 160mm rotor setups and rotor-adapter-free caliper fittings on some forks.
