It is the physical embodiment of "great things take time". It is not an offering that follows the crowd, designed around the latest trend or buzz of the market. Rather, a component that aims to add real value and benefit to the rider. Capable of not only pulling duty in a range of disciplines ranging from XC to light enduro but doing so with zero compromise makes the Mattoc "best-in-class"! The lightest, stiffest, and most tunable fork over more segments than any of its competitors, the Mattoc PRO is an amazingly versatile product capable of vastly improving your time in the saddle. At 1750 grams it is a featherweight solution given its wide travel range, yet its industry-leading stiffness lends it to a performance without rival. Consider also its amazing reliability and you have a fork that does it all and does it amazingly. A true, no-compromise, authentic fork, serving the real needs of the widest range of the mtb public and offering serious performance advantages to each individual one of them, no matter how they choose to ride.

The Dorado Air spring with IRT allows for an extremely lightweight build yet a suspension performance derived from our top-of-the-line DH fork. Compression damping via MC2 Sealed Cartridge with HBO technology and a sealed damper TPC for rebound, and you’ve got yourself an extremely sophisticated piece of suspension technology. Adjustable Air, IRT, Rebound, High and Low-Speed compression make for perhaps the most tunable, personalized custom performance suspension solution available on the market. Include all of this technology into an extremely stiff, reliable, 1750 gram package and you have a ride-changing component that is the envy of the industry

Key Features

59 grams decrease from the previous model.
Over 19% stiffness increase from the previous 27.5” 160mm to new 27.5” 150mm. 29” Stiffness increases are higher.
DoradoTM air allows for internal travel adjustments with no added parts. New travel spacers account for negative air volume change, so the 110mm fork has the same initial stroke feel as the 150mm.
Dorado Air spring systems contain a unique balancing valve that equalizes the positive and negative air chambers during the air fill process. This gives the spring rate a consistent feel without any flat or dead spots in the stroke, along with giving riders of different weights the same initial stroke feel. Dorado Air is our lightest weight air spring technology.
Infinite Rate TuneTM (IRT) allows for advanced spring tuning by independently adjusting air pressures at the beginning and end stroke. IRT technology creates a secondary positive air spring that affects only the middle to end stroke of the fork. This allows the main air spring to be set to lower pressures for improved small bump sensitivity while maintaining mid-stroke support and moderate to aggressive end-stroke ramp-up.
Sealed Dampers offer more consistent damping and lighter break away force, especially over long descents. Our Damper uses a bladder system to compensate for head build up along with a relief valve. Using both systems give us consistency along with long service life. Having non adjustable HBO eases setup for the user.
TSR (Trail Side Relief) casting bleed screws allow users to release casting pressure from the fork. Releasing casting pressure can improve overall fork feel and small bump compliance.

Suspension Forks Sizing

A new suspension fork is one of the most noticeable and worthy upgrades you can make to your mountain bike. A higher quality fork will be able to deal with more difficult terrain, remaining composed on the trail and keeping your wheel in contact with the ground. This gives more grip, and therefore a more confidence inspiring ride.

Not all forks are made equal, there are some very important size and compatibility aspects to look at first.

Compatibility

Wheel size

There are a few different wheel sizes for mountain bikes. 26”, 27.5” (650b) and 29” are the most common.

There is also plus (+) and fat versions available. If you are not sure it should be written on the side of the tyre.

Whatever wheel size you have, the fork must be designed to suit.

Fork steerer

The fork steerer is attached to the fork crown, this comes up through the frame and headset to be clamped at the top by the stem.

Most modern bikes will have a tapered steerer, this is 1.5” inch wide at the fork and 1 1/8th inch at the stem. Some DH bikes and older mountain bikes will suit a straight 1 1/8th inch steerer.

It is easiest and best if the replacement fork has the same diameter steerer to fit into your frame and headset.

If you are unsure on the size, drop the forks out from the frame and you should be able to see straight away if the steerer is tapered or straight.

Axle size

If you are planning on using the same front wheel with your new fork, the fork’s dropouts must suit your wheel.

The width of the front hub has traditionally been 100mm, with either a 9 or 15mm axle. With a 9mm Quick Release (QR), a fork could be described as 9mm x100mm or QR to fit. A larger 15mm bolt through axle is more common on higher end bikes, a fork could be described as 15 x 100 to suit. This 15mm axle can be a quick release style and can be referred to as 15QR

Over the last few years, a wider 110mm spacing known as “Boost” has become the new standard, this is not available for 9mm QR axles and would be shown as 15mm x 110 or 15mm Boost.

20mm axles have been common on DH bikes for some time. Although DH wheels will be 110mm wide, they are not always “Boost”. There is a new DH Boost for front wheels and forks, this means the hub is still 110mm wide, but the disc rotor/mount sits 5mm out.

Travel

The amount of distance the fork can move vertically is referred to as travel (shown in mm). The frame manufacturer will have designed the bike around a certain amount of travel. The general rule is to stay with this. Increasing or decreasing the fork travel can result in the geometry being severely compromised, making the bike handle worse than intended and putting more stress on the headtube structure.

*Changing fork travel can void frame warranty from the manufacturer, please check with the manufacturer before any travel increase/decrease.

As fork travel increases so can flex, to combat this a triple clamp design is used for forks with over 180mm of travel. The hub plus the two crowns creates a triple clamp. The forks are for DH use.

A triple clamp DH fork, travel is measured from the lower crown to the top of the fork lower legs

Offset/Rake

The distance the axle is offset from the steering axis. This directly affects the “Trail”. Trail is the distance between the contact point of the tyre and where the steering axis hits the floor. The shorter the offset the longer the trail and vice versa. Wheelsize also affects trail. Larger wheels have a longer trail. With the popularity of 29er MTB’s, there is often an offset choice to be made.

The most common offset for a 29er fork is 51mm, however, fork manufacturers offer shorter offsets to increase trail.

Fitting

Once the correct fork has been chosen there are a few things you should know before fitting.

Crown race – Slid down over the steerer is the crown race, these are usually particular to the headset on your bike. They create a seat for the lower bearings of the headset to sit on, this should be removed from your forks and slid into place on the new fork steerer before installing the new forks.

Star Nut – Inside the steerer tube there is a star nut. This has a wedge design allowing it to be slid down into place but not slid back up. There is an internal thread that takes the top cap bolt allowing the forks to be held in place and allowing adjustment of the pressure on the bearings.

Steerer length – A new fork will have a long uncut steerer, this will more than likely need to be cut to match the length of your original forks, however, it can be cut longer or shorter if you wanted to have more adjustment for stem height.
