2011 Magura Thor
Magura's unique dual arch design
For 2011 Magura makes some drastic changes to their Thor all-mountain/trail fork that see it not only gain steerer tube options, but also revised damping to suit more aggressive riders or terrain. The air sprung 140 mm Thor will be available in a standard 1-1/8" steerer tube, as well as both tapered and a full length 1-1/2" options that should make this already precise dual arch fork even stiffer. At the opposite end you'll find a full sized 20 mm thru-axle tying everything together. New graphics also distinguish the 2011 model from previous offerings, but you'll still find the handy air chart on the lower leg that aids in setup. While the above changes are far more visible, aggressive riders may benefit even more from internal changes that are not as easy to see. The Thor gets updated with much heavier compression damping via a revised shim stack that should help it maintain its composure better at speed. Magura had side by side damping assemblies out of a fork that made the comparison between the 2011 system and previous years easy to do - the difference was massive
. For those riders who prefer the original setup, it will still be available aftermarket if you wish to convert your fork to last year's damping. Another change includes the use of a far more progressive air spring that will require lower pressures, thereby increasing small bump sensitivity. From the outside the Thor looks similar to previous years, but the internal changes basically render this version a whole new fork.

Anodized aluminum dials
Sedona offers some amazing and challenging riding that allowed me to really feel what the Thor had to offer. Trail conditions varied greatly from smooth and fast slick rock that offered near limitless traction, to rough, rocky sections that would tax any bike when hit at speed. All of the rides involved a fair bit of climbing, some of it up some very technical pitches that required lots of horsepower and the right line choice. My bike for all of this was a 140mm travel Magura Thor equipped Cannondale RZ140. My last experience with a Magura fork was a Wotan, which I was fond of, but wished it had a more controlled compression stroke. The Thor was a revelation in this regard with its new higher level of low speed compression damping. I tend to push suspension in this travel bracket quite hard and therefore find myself having to run higher pressures than the manufacturer recommends due to light valving that is intended for tamer riding, but the new Thor performed admirably in this department. While the fork was supple enough to deal with the small ledges and steps that littered all of the trails we rode, it rode high in its travel and didn't suffer from excessive diving under hard braking, something that not a lot of forks in this category can brag about. Riding fast on unfamiliar terrain can often result in some surprises, but the Thor never once bottomed hard enough to cause any concern, and in fact felt much more progressive than I had been expecting. The Albert Select system works as advertised and the dials are high quality anodized aluminum pieces, although they were a bit hard to turn. The Thor's rebound adjuster is a plastic dial located at the bottom of the damping leg and has a usable, if a bit small, range of adjustment. The Thor is an incredibly torsionally stiff fork, especially for its 3.9 lb. weight. The fork's stiffness, combined with its ability to stay high in its travel under braking or on steep sections, meant that it was confidence inspiring on the difficult Sedona terrain. While far from a proper test, I only had three solid days of riding on the 2011 Thor, I was very pleased with how the 140 mm travel fork handled the challenging terrain.

2011 Magura Marta FR Brakes
Have a look at this neat video of some Magura rotor "testing" that was made by grinsekater.pinkbike.com
2011 Magura Marta FR brake
Magura's venerable Marta brake is back for 2011 with an updated FR version that comes stock with the new 180 mm Storm SL rotors that keep the weight low and the power high. The Marta FR is a mid-weight brake that comes in lighter than a DH specific model, but still has the power to slow down any long travel bike when used with the appropriate rotor size. Magura was also showing off their brand new Storm and Storm SL rotors that shave grams and improve braking performance. The new SL models are claimed to be up to 50% lighter than last season's standard rotors! The new rotors are available in all common sizes, including a pint sized 140 mm version. They will only be offered in standard six hole mounting patterns, although a Center Lock adapter is in the works.
