Trek Marlin 7 Gen 3 - Keswick

Below is the recommended sizing for the Trek Marlin 7 Gen 3 . Here you should measure your height with your shoes off.

Please Note: Many bike brands' size guides overlap slightly. This is because small adjustments like seat position can accommodate riders who fall between sizes. When you're in this overlap zone, the choice comes down to preference: a larger size for a more stretched-out ride, or a smaller size for a more compact feel.

At MTB Monster, we help customers on a daily basis choose the right size bike for their needs. We consider your measurements, riding style, and past bikes to help recommend the best size. If you're in doubt at all or want to just confirm your thoughts please contact us and we would be glad to help.

Invisiframe in our opinion is money well spent. Your bike is an expensive investment and invisiframe helps to protect your paintwork from scratches, scuffs and chips to keep your bike looking spotless for years to come. In essence, invisiframe is a custom cut, self healing frame protection film made from XPEL Ultimate Plus Gloss or Stealth Matte automotive grade film which is stain resistant and non-yellowing. It is commonly used for protecting paintwork on supercars and race cars. There are a number of different manufacturers producing kits, we have worked directly with Invisiframe since the start and they have always produced very high quality kits with maximum coverage and are a family run business who love biking just like us. Kits are available in both gloss and Matte finishes and unless specifically requested we would order the kit to match the finish of your paintwork. Some bikes have a mixture of matte and gloss paintwork and in most cases mixed finish kits are available. The material of an Invisiframe kit will act as an extra layer of clear coat and can make the finish of raw carbon more prominent due to the way that the light refracts. Similarly, fitting a matte finish kit can produce a more satin finish and mean that the kit is slightly more visible than when it is installed on a gloss finish.

You normally have 3 options with the invisiframe option

1. Supply and fit.

Our trained and experienced mechanics can install Invisiframe kits here so that your Trek Marlin 7 Gen 3 arrives fully protected and ready to ride. We recommend a 3-4 day curing period to ensure that the film adheres properly to the frame so your order will take a little longer to arrive but it will be well worth the wait..

2. Supply Only.

If you choose to install the kit yourself, we'll provide you with kit, instructions and a squeegee. Just select "Supply Only" and your kit will arrive with your bike, there is no delay to dispatch with this option. There are many informative videos online to guide you through installation. We would advise watching these in advance to see if you feel confident to fit the kit. Patience is a must when it comes to installation.

3. N/A

Choose this option, if you would prefer not to have invisiframe fitting.

Please note, if no invisiframe kit has been designed for the bike yet, no option other than N/A will appear. However, there is a very good chance we may still be able to get one designed or custom templated to fit this bike. If this is of interest, please contact us here and we can look into it as soon as possible.

So, what's a tubeless setup? Traditionally, inner tubes are inflated with air to create a cushion between the rim and tyre. In contrast, a tubeless setup ditches the inner tube and relies on a specially designed rim with an airtight seal. A self-sealing liquid is added directly inside the tire, and air is pumped through a special valve to inflate the tyre. This allows riders to run lower pressures for better grip and comfort, and the sealant can plug small punctures on the fly, reducing flats.

However, it's important to note that bike manufacturers send their bikes to us in varying degrees of readiness to be set up tubeless. For example, some may supply suitable tubeless-ready tyres, but not the valves or sealant, while others arrive with everything you need. So here at MTB Monster we've checked and answered the following two questions;

Can the Trek Marlin 7 Gen 3 be set up tubeless? No, this bike cannot be set up tubeless.

What option do I need to select, if I want the bike setting up tubeless before I receive it? Unfortunately, this bike is not supplied with tubeless tyres and therefore cannot be set up in the current configuration. While the rims may be listed as tubeless ready, the tyres fitted are not tubeless rated and could cause a blowout, this is a critical safety risk as such we would not be able to set the bike up tubeless. If you would like to set the bike up tubeless, this will require a set of tubeless compatible tyres, pleasecontact a member of our team who will be able to help you.

In the box, you'll find your owner's manuals with your Pre-Delivery Inspection Checklist, signed off by our Cytec qualified mechanic. This details all the checks that have been completed along with an 'Important Information' sheet explaining the advised pre-ride checks to be carried out to ensure the bike is safe to ride and that it will perform at its best. We advise keeping this document safe in case it is required in the future.

We also include the relevant allen keys to assemble your bike (normally 2), brake separators to keep your brakes apart whilst the wheel is out of the bike along with any manufacturers manuals, and any extras the brand has included. Some manuals are now only accessible online and paper copies are not included, if you require any assistance accessing manuals for your new purchase please get in touch.

It is worth being aware that bikes are rarely supplied with pedals included. This information will be detailed in the specification of the model you choose. If your bike is not supplied with pedals and you don't currently have any suitable ones, we have a great range on offer here

Any promotional freebies such as an MTB Monster mudguard will also be included in your box.

If you feel you are missing any parts of your kit please contact us within 24 hours of delivery so that we can help.

Showroom Viewing

While we showcase Trek bikes and often have the Marlin model on display, we can't guarantee the exact bike you see online will be ready to view at any given time. This is because bikes might be recently sold, boxed in our warehouse, or still with the manufacturer. To ensure you see a specific bike you're interested in, please contact us before your visit & we'll do our best to have it available on the day of your visit or make alternative arrangements.

Can I demo & test ride the Trek Marlin 7 Gen 3?

The bike is classed as a Cross Country bike.

Like all mountain bikes, the Trek Marlin 7 Gen 3 can be used on gravel paths and forest tracks, but the bike will really excel on smoother, single-track off-road trails with minimal technical features. Can be used for both road and off-road riding.

Cleaning a bike doesn’t need to be overcomplicated, a brush and hose pressure method is the best way. We advise against using a pressure washer as this often drives water behind seals, washing grease from bearings and also forces water into electrical components. It's also best to avoid any harsh chemicals or abrasive cleaners as these can damage the finish of the frame and components. MTB Monster offer a range of recommended cleaning products that are designed for ebikes and non-ebikes.

Over the past four decades, Trek have been at the forefront of the industry, continually challenging the limits of bike design in order to be a manufacturer that builds bikes that people love.

Trek haven’t just stumbled upon being one of the largest and most respected bike brands in the world by chance. Through their commitment to quality, performance and customer care, Trek have built a solid reputation, befitting of their bikes. Our staff ride Trek’s so if you want to know any details that only an owner would know, let us know and we will be happy to help.

Getting started can seem daunting but there's only a couple of kit items that are essential for a safe and self-sufficient bike ride.

Above all else, a helmet is the most essential piece of kit. It dramatically increases safety when you're out riding. To put this in context, if you visited a UK mountain bike trail centre, you'd be hard-pressed to find anyone riding without one. Rider protection wise, this can be extended to gloves, knee pads and elbow pads depending on type the terrain that you are looking to tackle.

We would always recommend riding with a spare inner tube, tyre levers and pump. Most riders have a story about the time they got caught out with a puncture, usually in horrible weather and miles from the endpoint of the ride, learn from our mistakes :) Additionally, a number of mechanicals can be resolved on the trail with a handy multi-tool, these usually contain a range of hex keys, torx keys and occasionally a chain breaker to help you get to the end of the ride and into a fully equipped workshop.

For any additional advice, feel free to contact us and we'll be more than happy to help.

Components fitted the bike

All components fitted to the bike are covered under warranty by the respective manufacturer which is typically two years however in some cases, this can vary and items such as suspension are subject to servicing being carried out.

Whether or not a bike is supplied with pedals is at the discretion of the manufacturer. If you select the technical tab on any product page you will see 'pedals' as a one of the items and here it will tell you if they come as standard from the manufacturer. By reducing the number of components included with a new bike, manufacturers can minimise waste and packaging. With so many different types of pedal available it's unlikely that anything manufacturers include will suit everyone. If you require pedals and they are not listed as included in the specification of your chosen bike you can find the range that we offer here and of course if you are unsure please get in touch for some friendly advice.

Yes, all of the brands we deal with carry a large number of spare parts to support their customers. If you have purchased a bike from MTB Monster, our rider support team will work with you and the team at Trek to get you the parts you need as soon as possible.

Yes, most upgrades on the Trek Marlin 7 Gen 3 are fine, if you fancy changing the brakes, adding some blingy new grips, or maybe a change of fork, you're welcome to make these changes. However, just make sure they are both suitable & compatible with the bike.
