Shimano Claris 2 × 8-Speed Drivetrain

The SUNPEED KEPLER features a complete Shimano Claris R2000 shifting system with two front chainrings and an eight-speed rear cassette.

The drivetrain combines:

• Shimano Claris R2000 shifters
• Shimano Claris R2000 2-speed front derailleur

This setup provides 16 gear combinations, giving riders a practical range for city streets, open roads, rolling terrain and moderate climbs.

50/34T Compact Crankset

The Prowheel PRL aluminum 50/34T crankset provides two front chainring options.

The 50T chainring supports efficient higher-speed riding on flatter roads, while the 34T chainring provides easier gearing for climbs, longer rides and changing terrain.

Combined with the 11–34T rear cassette, the drivetrain provides a versatile gear range for commuting, fitness and endurance cycling.

Mechanical Disc Brakes

The KEPLER features BOLI BB7 mechanical disc brakes with 160 mm rotors at both the front and rear wheels.

The dual-disc system provides controlled braking for:

• Urban commuting
• Road cycling
• Gravel routes
• Descents
• Recreational riding
• Changing riding conditions

700 × 40C CST Tyres

The 700 × 40C CST tyres provide a wider profile than traditional narrow road-racing tyres, delivering a practical balance of rolling efficiency, traction and riding comfort.

The 40 mm width makes the KEPLER suitable for paved roads while providing additional stability and cushioning on light gravel and mixed-surface routes.

Lightweight Aluminum Frame & Fork

The SUNPEED KEPLER uses an aluminum-alloy frame and rigid aluminum fork to provide responsive handling and a lightweight overall construction.

With a listed net weight of 10.7 kg, the bicycle is easy to handle during commuting, recreational riding and longer cycling sessions.

30 mm Aluminum Wheelset

The KEPLER features a 30 mm aluminum-alloy wheelset paired with SOLON quick-release disc hubs.

Front Hub: SOLON DH501F Aluminum Quick-Release Disc Hub
Rear Hub: SOLON DH502R Aluminum Cassette Quick-Release Disc Hub

The quick-release design provides convenient wheel removal for transportation, maintenance and tyre servicing.

• Road cycling
• Fitness cycling

Riding Comfort & Control

The combination of 700 × 40C tyres, rigid aluminum fork, lightweight frame and comfortable saddle creates a responsive bicycle with additional tyre volume for everyday riding comfort.

The wider tyres provide additional cushioning over rough pavement and light gravel while maintaining efficient rolling characteristics for road use.

Safety Information

Wear an appropriate cycling helmet and inspect the brakes, tyres, wheels, drivetrain, quick-release mechanisms and frame fasteners before every ride.

Ensure both wheel quick-release systems are correctly secured and the mechanical disc brakes are properly adjusted before riding.
