Upgrades and Accessories

As an entry-level mountain bike with several attractive features and specifications, customizing and upgrading the Trek Marlin 6 can significantly enhance your mountain biking experience.

Handlebars and Saddles

One of the first upgrades you might consider for your Trek Marlin 6 is a new handlebar or saddle that better fits your preferences. An example of a great handlebar upgrade would be the Raceface stem to improve the handling and responsiveness during your ride.

For saddles, various choices include weight, cushioning, and material like steel rails. Some notable options include saddles made of XR2 Comp or the more budget-friendly saddles made of Bontrager alloy. These provide comfort and durability for riders tackling rough terrains for extended periods.

Additional Mounts

To enhance both performance and convenience, add-ons and mounts are available on the Trek Marlin 6. One versatile component is the Blendr Stem, which allows for quick, secure attachment of items such as lights, GPS devices, and action cameras.

Moreover, for practical storage options, update your mountain bike with rear rack and kickstand mounts, accommodating pannier bags, or other storage solutions.

These mounts complement front suspension forks like the SR Suntour XCT 30, which improves the bike's ability to carry additional weight.


Upgrading pedals on mountain bikes can significantly improve your riding experience, especially for first-time mountain bikers. High-quality, durable pedals are available for a range of budgets, such as the affordable pedals that can be found for $40-50 or sometimes less.

Environmental factors and different riding styles mean that pedals will undergo different levels of wear and tear, so remember to maintain and replace your pedals as required.

Hydration Solutions

Numerous options are available for attaching water bottle cages and hydration packs. Consider, for example, incorporating either XS or ML L XL XXL Bontrager alloy cages that suit different frame sizes to ensure your water bottle remains secure and accessible throughout your ride.

Utilizing a hydration pack is another option, which not only provides water but also offers additional storage for essential tools, spare clothing, and snacks. Indeed, having the right hydration solutions can make the difference between a great ride and a miserable journey.

Maintenance and Warranty

It's essential to maintain your bike's chain. A well-kept chain ensures smooth gear shifts and improved performance. Remember to clean it regularly and apply chain lubricant when necessary.

Another vital maintenance aspect is caring for your bike's hydraulic disc brakes. The Trek Marlin 6 comes with powerful Tektro hydraulic disc brakes, which provide reliable stopping power even in rough terrain. Regularly check your brake pads for wear and replace them when needed.

Below are some additional maintenance tips to help prolong your bike's life:

  • Clean your bike regularly to prevent dirt buildup in delicate components.
  • Apply grease to your seat tube and other moving parts to prevent rust.
  • Check your tires' air pressure and maximum width before every ride.
  • Inspect cables for fraying or damage, and replace them when necessary.
