MAGURA Presscamp´14/’15 – new MT Next Series: by c_g

0-Logo

It is about 3 years since MAGURA introduced their MT disc brakes to the world, featuring the revolutionary Carbotecture technology and an astonishingly low weight. Last weekend I have had the opportunity, to attend the introduction of their 2nd generation MT brakes on the beautiful island of Mallorca, Spain. The new series is called MAGURA MT Next and will consist of strongly reworked line of dual piston brakes and adding a set of 4-piston brakes. We had the opportunity to really pick the engineers´ minds and so the sheer volume of information is plenty enough to do two posts on the disc brakes alone.

Carbotecture remains to be the central theme for the master caliper/brake lever, only MAGURA is using it even more of its potential in the next generation. „Much of the basics have remained, but some fundamentals have changed.

3-MAGURA-MT-Next

The basic principle is pretty simple and called „weightRATIOperformance“: The lighter the lever unit is executed, the less restraints are there to create a maximum heat resistant caliper while still keeping the complete weight competitively low. It is a physical reality, that energy dissipation is directly related to the mass and surface of the caliper and every gram added here helps in keeping the brakes from fading. So MAGURA worked hard to get the weight ratio for the lever as low as 20% when compared to the 80% of the caliper, rotor and housing.

MAGURA-Carbotexture

As mentioned MAGURA’s Carbotecture technology plays a vital role here – allowing incredibly light lever units – know-how MAGURA has acquired and perfected over a long time supplying high end manufacturers (e.g. BMW) with corresponding products. Other than often misconceived, the Carbotecture units are by no means simple „plastic“ pieces, but highly advanced injection molded carbon/resin pieces, that can be manufactured to incredible precision and surface smoothness if required. According to the engineers I talked to the units are so refined, they need absolutely no finishing work after molding, not even with the piston and seal sections that are so vital to keep the brakes working perfectly long term. There are two Carbotecture versions – the standard one using shorter fibers and therefore requiring more material and the Carbotecture SL (as used in the top models) that utilized longer carbon fibers keeping weight as low as possible while remaining tough and stiff. Over all Carbotecture has about half the density of Aluminum – which shows the weight saving potential there.

MT8-Geberkolben-label

Other things that have remained unchanged, are the radial piston design of the lever unit, and the hydraulic ratios employed, as MAGURA felt, there had been spot on already. But other than that the lever units have seen a complete redesign and here are the main features listed:

1. The lever pivot point has moved a radical 20 mm closer to the lever allowing a better ergonomic position for more power and more natural feeling modulation.

2. The volume of the oil reservoir has doubled over the former model, maximizing heat tolerance and keeping fading very low even when the descents are long and steep.

3. The sealing architecture of the lever has been completely reworked now using a machined alloy inner piston, a fixed primary seal and better performing secondary seals – if you are not familiar with these terms it basically means seals will have less mechanical strain on them during braking and thus hold up longer and better long term.

4. Toll-less braking point adjustment (BAT) and lever reach adjustment on the top models (MT6, MT7 und MT8). The BAT is primarily for synchronizing the front and rear brake feel, but also is said to help in getting the brake feeling softer or more crisply.

5. Not really new but definitely worth mentioning is the Easy Bleed Technology, which means one can bleed the system with a bit of mineral oil any medical standard syringe. Dead simple and no hassle with adapters and fragile threads.

The 2-piston caliper of the existing range (MT2, MT4, MT6 and MT8) had also seen some modifications for better heat management – meaning they have received a more organic and smooth shape (more surface) gained a few grams, but overall the differences are not that dramatic.

The pistons remain to be 22mm in diameter and the caliper is still a one piece forged unit for maximum stiffness. Also unaltered is the magnetic pad holding mechanism, which keeps the pads in place and rattle free without any extra springs or such – securing is still done via a small set screw at the top, the top loading pads, which allow pad exchange without taking off the wheels and of course the much beloved „Royal Blood“ mineral oil as hydraulic medium.

MAGURA-MT-Next-2_Kolben-

So much for the introduction of the brand new MAGURA MT Next 2-piston brakes. Here come the exact specs as communicated at this point (sorry, only Euro prices for now):

MT2_white

MT2 – The MT2 is a really hot piece of equipment for the money. It is exceptionally light with its Carbotecture lever, is super stiff by the one piece caliper (2-piece on the current model), yet still very light for an entry level set of brakes (claimed: 370 g/unit incl. rotor and adapter). It already has a lever reach adjustment and is supposed to have plenty of power with a very good modulation for even novice riders. Expect to see these brakes specified on a lot of bikes next year.

Features:

• Ergonomic 2-finger Carbotecture brake lever, Carbotecture housing and Carbotecture handlebar clamp

• Adjustable lever reach

• All-in-one, 2-piston brake caliper, glossy black

• All screws with Torx T25

• magnetiXchange brake pistons for easy brake pad replacement

• At only 365g*, one of the lightest brakes in its class

• Compatible with all MAGURA Storm and Storm SL discs

• Available at dealers by June 2014

• Msrp: € 79,- (incl. disc and adapter)

 MT4_white

MT4 – Great braking performance and exceptional reliability is where the MT4 brakes are supposed to shine. They are mid-range all around performers with same updates as the MT2 but featuring stiffer and lighter alloy 2-finger levers and a reinforced hose design, plus a rotate-able banjo.

 

Features:

• Ergonomic, 2-finger, hollow aluminum anodized lever (aluminum two-finger brake lever)

• Carbotecture housing & handlebar clamp, aluminum cover

• All-in-one, forged, 2-piston brake caliper with banjo, polished black anodized

• All screws with Torx T25

• magnetiXchange brake pistons for easy brake pad replacement

• Compatible with all MAGURA Storm and Storm SL discs

• Available at dealers by June 2014

• Msrp: € 119,- (incl. disc and adapter)

MT6_white

MT6 – High-End features and performance at a very reasonable price. The MT6 get the stiffer and lighter Carbotecture SL lever body, a different mechanical lever ratio (by means of a variable ratio pin pushing down on the piston). It also already has the tool free brake point and reach adjustment.

 

Features:

• Carbotecture SL housing & aluminum handlebar clamp, aluminum cover

• High-quality, ergonomic and finely-crafted 2-finger brake lever with sportive, classic optics

• Toolless adjustment of lever reach and bite point

• Forged, ergonomic, 2-finger, hollow aluminum anodized lever (aluminum two-finger brake lever)

MT8_white-1024x893

MT8 – Everything and more. The new MT8 features all the technologies we currently have available – a full carbon lever unit with Carbotecture SL lever housing, the woven, Carbolay 2-finger Carbon-lever , and the user friendly tool-free pressure point and lever reach adjustment.

 

Features:

• Full-carbon brake lever

• Optimal heat resistance

• Tool-less adjustment of lever reach and bite point

• Forged, 2-piston, aluminum brake caliper, mystic grey anodized

• 2-piston brake caliper with banjo, polished black anodized

• At only 299g*, the lightest brake in the MAGURA range

• Compatible with all MAGURA Storm and Storm SL discs

• Available at dealers by June 2014

• Msrp: € 319,- (incl. disc and adapter)

Of course all MT brakes are compatible with MAGURA’s standard Storm rotors (160-203mm), as well as the weight optimized Storm SL rotors (140-203mm). Note that MAGURA uses wider rotors with 2.0mm thickness instead of the more common 1.8mm of the competitors.

So much for the 2015 MAGURA MT Next 2-piston brakes, which already got us impressed, but we still have ti cover the MT Next 4-piston brakes and let you know how they rode on the Mediterranean trails of Mallorca. Stay tuned.

 

RIDE ON,
