Who is the Domane+ SLR 7 AXS For?

It's designed for road cyclists who value lightness, traditional aesthetics and natural assistance. Ideal if:

• You want to maintain high averages on long rides without arriving exhausted.
• You need extra help on demanding passes or to keep up with a stronger group.
• You won't compromise on the aesthetics or dynamics of a premium carbon bike.

TQ-HPR50 Motor: Nearly Silent Power

Unlike other bulkier motors, the HPR50 uses a harmonic pin-ring system that eliminates noise and vibration, offering a very organic pedaling feel. With 50 Nm of torque, it pushes hard on ramps without exceeding the European 25 km/h legal limit, and you'll barely notice resistance when you exceed that speed.

OCLV 800 Frame: Rigidity and Comfort Balanced

The 800 Series carbon is Trek's lightest, allowing total weight comparable to many conventional competition bikes. Rear IsoSpeed technology absorbs vibrations, keeping the cyclist fresh on marathon days.

SRAM Force eTap AXS 1×12 Transmission

Wireless electronic shifts that offer millimeter precision and fewer exposed components. The 10-44 tooth cassette, combined with a 42T chainring, provides enough range for hard climbs without abrupt gear changes.

Real Range and Charging Options

The 360 Wh integrated battery delivers between 60 km (Max mode) and 100 km (Eco mode). Adding the optional 160 Wh Range Extender, available at CaranvaSports, you can reach close to 145 km on endurance rides. The Range Extender charges in approximately 2 hours 30 minutes.
