    Strengths:    Strong hydraulic stopping power, nice look.

    Weaknesses:    Takes a long time to get these dialed in just right, not to mention tons of maintenance.

    Bottom Line:   
    If you have tons of time to adjust these very regularly then these are for you. These brakes could stop a train but making sure they are dialed in all the time is really a pain.

    Strengths:    Great for cross country riding

    Weaknesses:    Horrible for downhills. Rear brake constantly overheats to the point I have to stop and spray with water to cool!

    Bottom Line:   
    Great for buzzing around the woods on the east coast without a lot of hills, great for stopping on the x country single track.

    I moved to Co and the "hills" here are just too big for these breaks...

    Depending on where you ride, take my advice!

    Strengths:    Good modulation, plenty of power, ease of maintanence, parts easily available, they will take hard use all day long!

    Weaknesses:    none,after flogging them for 4 years!

    Bottom Line:   
    These came stock on the bike. I swapped the pads for EBC red up front& green in back. EBC's make a big differance and they wear long. I run the 6" rotors front& rear. Pad changes are easily accomplished without disassembly. Bleeding, when necessary, is a simple operation. I've never experienced any overheating,fading or lock-up. After 4years of HARD riding there have been no leaks and no worn out or faulty parts. Bottom line,For downhill or XC use. Plenty of power! Dependable!!

    Strengths:    came stock on bike, look very nice. the levers are really pretty, stopping power

    Weaknesses:    they will pump up, and overheat, thus locking the brakes on hot days.

    Bottom Line:   
    well, these brakes were really nice until I rode on a hot day with them, where they would heat up and lock the brakes.

    The brake fluid started to spill out of the levers, which at that point I took them back for warranty, and I got Deore Hydros instead. They are cheaper, and I have not had any problems with them at all.

    Strengths:    These brakes could stop a train. They have great adj. features and a kick ass look to them with those two-piece meaty rotors.

    Weaknesses:    They weigh a bunch. Don't get the if you ride cross counrty.

    Bottom Line:   
    These brakes will do a better job than dh systems twice their price. They are meant for tandoms and other heavy duty apps. but are perfect for freeride because they are so freakin burley. Get a 7.5" rotor for the front and swap the 6" to the rear and you'll learn the true meaning of power.

    Strengths:    It's a disc brake and it's better than a rim brake.
    Once it's well installed, it's very good.


    Weaknesses:    Difficult to find suppliers for the break pads (I only know one supplier in Belgium). Nobody else seems to use it so no experience in maintenance, which obliges me to do it myself.

    Bottom Line:   
    I never used any other disc brake so I can't really compare. After some trials I succeeded in changing pads in 10 minutes. Also the bleeding I do myself, and it's quite easy once you've done it a few times.

    Compared to newer disc brake types that appeared the last years (like Formula B4, Shimano XTR, Magura, ..) I honestly believe that Formula Evoluzione are very good brakes, that's my conclusion after hearing reactions from many other users.
    The main difference with other disc brake types is the heigh weight.

    Strengths:    fairly good lever feel, good modulation

    Weaknesses:    not a lot of pure power. Fine for XC, but nothing else. Bleeding and replacing pads is a PAIN. You must take the caliper appart and bleed to replace the pads! Non-standard rotor, so replacing is a pain.

    Bottom Line:   
    In all honesty, don't buy these brakes aftermarket. If they came on the bike, fine. I am planning on replacing them once I replace the pads again. (I just put on EBC Reds) If they are dialed in perfectly, they are fine, if not, they suck. Maintenence is a HUGE PAIN.

    Strengths:    good feel, awesome modulation, price isnt on the steep side, and i haven't to have any matainence except bleeding

    Weaknesses:    i have a liquidy/watery sound when braking at slow speeds but is absent at higher speeds

    Bottom Line:   
    These are great brakes at a great price. I use them for XC racing and i love them except for the slow speed braking sound. If your looking for discs at low price you've met your match. They cant even beging to compete with V-brakes in inclimate weather or hot sunny days.

    Strengths:    Looks good, works good, the modulation is good, and relatively cheaper then the other (Hayes and XT)

    Weaknesses:    With the original pad and disc isn't so good

    Bottom Line:   
    I use this brakes with Grimeca's 185 mm discs. IMHO now i have reach the brake power, that i have hoped, and the disc can't owerheated now. To setup the brake you must have time and to bleed also difficult, but after this you get excellent modulation, and real power!

    Strengths:    Light Weight, Goodish looks, good modulation, green standard pads need to be upgraded to EBC reds to get better power.

    Weaknesses:    Not that easy to fill and bleed,not the power I would realy like,

    Bottom Line:   
    Not really the easiest system to look after. Discs are still supior to V's etc but I really think the constant fade in power from just serviced to weak is not what I would like from a disc. Will look at Hopes, Hayes and decide if its worth the spend.
