Magura Marta FR Review

Brakes Pro Reviews

Reviewed by Brian Mullin

When I first saw the Magura Marta FR at 2010 Interbike, I thought that they were a re-designed version of the Marta series, but in reality, it’s just a cosmetic change of the normal Marta, which is fine, since the line has an incredible pedigree. The new changes are the Grunge Green color scheme, white hydraulic lines, and a gray aluminum lever, otherwise it’s the same excellent product. Magura revamped the Marta line in 2009, and upgrades included a redesigned caliper and reservoir body, a better lever pivot, the use of the larger Louise pads and the new bleeding system (EBT). This year they added the Storm and Storm SL rotors, which are miles ahead of their predecessor’s, with lighter weight, and better power and modulation.


Magura Marta FR
The Marta FR brakes use an open hydraulic system, with an integrated reservoir and an expansion chamber for fluid temperature control. The aluminum caliper is a 74mm PM mounts, a one piece monoblock design, and uses two injection molded composite pistons for less heat transfer to the brake fluid, and the pistons are magnetized for brake pad attachment. The pads come in two models, the default 6.1 Performance version for maximum power, or the optional 6.2 Endurance version for longevity. The aluminum master cylinder, has an aluminum lever with reach adjust, and dual docking design for the shifter placement. The rotors are sold separately in 160, 180 and 203mm sizes (6 bolt IS) in either the default Storm or Storm SL rotors. Magura has a wide assortment of adapters so their PM caliper can fit any bike or fork, or Centerlock hub. The hydraulic fluid is Magura’s Royal Blood mineral oil, and the brakes are bled using their Easy Bleed Technology (EBT).


According to my sources, nothing has changed internally on the FR, but it seems to me that Magura has slowly been refining their quality control and assurance. The FR feels a bit tighter, and hasn’t required a bleed (sort of an anomaly with Magura brakes), and in general seem to have better tangible tolerances? I have used their Marta SL Mag and the Louise Carbon, which both have the light and gorgeous looking carbon lever, and to me the beefier aluminum lever on the FR seems less sloppy, though I wouldn’t call it flexy, since both lever types are stout. Although I have never broken a lever, the cost ratio of their aluminum replacement over a carbon is pretty hefty, so that adds another notch for usability to the FR. Initially I found the stark White hydraulic lines garish, but they have grown on me, and I think they add a nice splash of color to the bike (White is the new Black?). I liked the simple and understated Grunge Green color scheme, as it sort of blended in with whatever was on the bike. I tested the FR with a 180/160 and 203/160 rotor size combination’s, using both their Storm and Storm SL rotors, and always with the 6.1 Performance pads. The Storm is more powerful, though seems to lock up slightly easier, while the SL, which has substantial cutouts, has better feathering characteristics and less weight, and the latter was my preference. As always, with the Marta line, I wish they came with Quickfit split clamp system, that is found on the Louise, for faster installation and product swap out and changes.

The FR brakes weigh approximately 245 grams, and come with full length lines (1650mm/65 inches), and will need to be cut to size, dependent on user preference and bike geometry. Magura sent the test pair to me with my length specification (thanks!) and spec’ed for moto style, so I didn’t need to make any adjustments this time, but it’s a relatively simple process to shorten the lines. The new EBT (Easy Bleed Technology) system which uses a port on top of the reservoir is easy to use, and I have bled my Marta SL Mags a number of times, so I can vouch for the simplicity and ease of the system.

    Thanks for the write up. I have always liked the feel of the Magura’s. Its funny to me, I just replaced my brake lines with a sterling silver color and on the trail its the first thing people notice and ask where they can get a set. Garish for some liked by others eh?

  • Mark says:

    I also noticed you’re running your brake lines like the British do, front on the right and rear on the left. I rented a bike in Whales once and repeatedly nearly killed myself because I couldn’t get my mind to remember to tell my other hand to front is on the right.

    I prefer my brakes set up in moto style, with the front brake on the right side. Many years of motorcycle riding has my brain pretty attuned to using the right hand, and in addition, my right has finer motor skills for precision braking.

    Great rewiev, but i think these brakes are to expensive. I’ve had 09 version of Marta with 180mm wavy sl disc rotors and was having two problems. Brake levers were slowly leaking oil thru push rod and feeling spongy and the front brake vibrate like crazy. Marta from 09 use the same big brake pads as the Louise. Thats funny, because Magura dont recommend use of the lightweigt wavy sl rotor with Louise. So, I replace the brake levers with Shimano xt levers, and the sl disc rotors with Avid G3 rotors. The brakes become much more powerfull and the lever feel is more solid and stiff. I’m wondering how good the new MT line its gonna be. Cheers

    Thanks, I will hopefully have a set of the MT8’s sometime in early May?
