Product Information

Full details

The Trek Slash+ 9.7 is designed for aggressive trail riders seeking a mid-assist electric mountain bike that excels on challenging descents and long, demanding climbs. Its key benefit is the seamless integration of TQ's powerful yet natural-feeling HPR 60 motor and a substantial 580 Wh battery, offering ample boost without compromising the bike's ride dynamics. A potential caveat for some users might be the specific tuning of the suspension for rowdy terrain, which may feel firmer on smoother trails. This e-MTB features a robust OCLV Mountain Carbon frame, a 12-speed SRAM Eagle transmission, and Fox Performance suspension, making it ready for technical riding.

FAQs

What is the intended use for the Trek Slash+ 9.7?

The Trek Slash+ 9.7 is designed for aggressive trail riding, enduro, and demanding downhill and all-mountain use. Its mid-assist motor, robust suspension, and durable carbon frame make it ideal for challenging terrain.

How long does the 580 Wh battery typically last?

Battery life varies greatly depending on terrain, assist level, rider weight, and pedaling effort. On average, expect anywhere from 1 to 4 hours of ride time, with lower assist levels and flatter terrain offering longer durations.

Can I ride this bike in the rain or wet conditions?

Yes, the bike is designed to be ridden in various weather conditions. However, it's crucial to clean and dry the bike thoroughly after riding in wet or muddy conditions, especially focusing on the drivetrain and motor to prevent corrosion and ensure longevity.

What is the weight limit for the rider and cargo?

Trek specifies a system weight limit (rider, bike, and any cargo) of 300 lbs (136 kg) for this model. Always consult the latest Trek specifications for the most up-to-date information.

How do I adjust the angle-adjust headset?

The angle-adjust headset allows you to fine-tune the head tube angle for different riding conditions. Typically, this involves loosening specific bolts on the headset cups and rotating the adjustable crown race. Refer to the bike's manual or consult a qualified mechanic for detailed instructions.

Is this bike compatible with different wheel sizes?

The Slash+ 9.7 is designed around its specific wheel size and travel configuration. While some minor adjustments might be possible, using significantly different wheel sizes is not recommended and could negatively impact geometry, performance, and warranty.

What kind of maintenance does the TQ motor require?

The TQ HPR 60 motor is designed for low maintenance. Regular cleaning of the bike is important, and care should be taken not to direct high-pressure water jets at the motor housing. Any internal motor issues should be addressed by an authorized Trek dealer.

Troubleshooting

Motor not providing assist

Ensure the battery is charged and properly seated. Check the TQ LED display for error codes. Verify that assist is enabled via the controller and that the speed sensor is clean and properly aligned.

Reduced battery range

Ensure the battery is fully charged before each ride. Check tire pressure, as underinflated tires increase rolling resistance. Riding in lower assist modes will conserve battery life. Extreme cold temperatures can temporarily reduce battery performance.

Suspension feels harsh or bottoming out

Re-check suspension sag settings and air pressure. Ensure the rebound damping is adjusted correctly for your weight and riding style. Inspect suspension seals for damage or leaks.

Squeaking or creaking noises

Inspect and clean the drivetrain, particularly the chain and cassette. Check for loose bolts on the cranks, pedals, handlebars, and suspension pivots. Ensure the seatpost and saddle clamp are properly greased and tightened.

Brakes feel weak or noisy

Check brake pad wear and replace if necessary. Inspect rotors for contamination or damage. Ensure the brake fluid is not low and the system is not air-bound; bleeding may be required. Clean rotors with isopropyl alcohol.

Pros and Cons

Pros

  • Smooth and natural-feeling motor assist enhances ride quality.
  • Long-range battery capacity for extended adventures.
  • High-quality suspension components provide excellent trail capability.
  • Durable and lightweight carbon frame offers a premium feel.
  • Reliable and wide-range SRAM drivetrain for diverse terrain.

Cons

  • Mid-assist motor might feel less powerful on extremely steep, sustained climbs compared to full-power e-MTBs.
  • Suspension is tuned for aggressive riding, which might be firmer on less demanding trails.
  • May be heavier than non-electric mountain bikes, impacting maneuverability in certain situations.
  • Carbon frame requires careful handling and maintenance to prevent damage.

Setup, Compatibility & Care

Initial Setup:

  1. Tire Inflation: Inflate tires to the recommended pressure for your weight and riding conditions. Consult the tire sidewall or Bontrager documentation.
  2. Suspension Sag: Adjust the air pressure in the fork and rear shock to achieve the recommended sag (typically 20-30% for this type of bike). Refer to the Fox suspension manuals for specific instructions.
  3. Cockpit Adjustment: Adjust handlebar height, rotation, and lever positions for ergonomic comfort and control.
  4. Tire Setup: Ensure tires are properly seated on the rims. For tubeless setup, follow the manufacturer's instructions for sealant and rim tape.

Compatibility:

  • Drivetrain: The bike uses SRAM Eagle T-Type components, ensuring compatibility with other T-Type or Eagle AXS parts. UDH (Universal Derailleur Hanger) ensures compatibility with a wide range of modern drivetrains.
  • Wheels: Boost 110 front and Boost 148 rear hub spacing are standard for modern mountain bikes.
  • Bottom Bracket: Internal routing for components is standard.

Care and Maintenance:

  • Cleaning: Regularly clean the bike after muddy rides using water and mild soap. Avoid high-pressure washing directly on bearings or the motor unit.
  • Lubrication: Keep the chain clean and lubricated. Periodically inspect and lubricate suspension pivots.
  • Battery Care: Store the battery in a cool, dry place. Avoid full discharge and extreme temperatures. Follow TQ battery charging guidelines.
  • Brake Maintenance: Check brake pad wear and fluid levels regularly. Bed in new brake pads for optimal performance.
  • General Inspection: Periodically check all bolts for tightness, especially headset, stem, and suspension pivots.
