    Strengths:    Relatively squeal-free

    Weaknesses:    Front brake is visibly flexy. This spooks me and has me convinced it'll someday break right from the fork mounts.

    Bottom Line:   
    These brakes are ultra-finicky to set-up. The front brake flexes noticably. They are intolerant of too much length in brake housing. The odd-sized rear rotor makes replacement rough (its a 145mm--Hope makes one, but its expensive). The front is a relatively common 160mm. These brakes operated poorly with the Deore levers that came OEM with the bike, but the Tektro levers certainly improved things. These brakes aren't for upgrade. Better cheap Discs are available from RST, Suntour, Tektro, or Promax. If they came stock, they'll make do until you waste them.

    Strengths:    well all you gotta do is take off the pads and the one with the spiral side you put white grease behind it just a little and remove that rubber seal its the main problem

    Weaknesses:    there is none if you know how to mod things cause they awsome when it comes to trick ridin but long hard stops is where the price starts to show

    Bottom Line:   
    the brake is alright it is perfect 4 what i do so owell recall

    Strengths:    none. absolute crap.

    Weaknesses:    everything

    Bottom Line:   
    Stay away if you value your life. There is nothing like the feeling of no braking power while going down a hill. Or worse than that, locking on and flipping you over onto your face. STAY AWAY FROM THESE IF YOU VALUE YOUR LIFE!!!!!!!

    Strengths:    Last a long time. Probably 1000 landings...only replaced the pads once, and they were not worn out.

    Weaknesses:    It was tough making the brackets to mount the rotor and the caliper mount.

    Bottom Line:   
    I use my Diatechs on a 600-pound (gross) ultralight aircraft. They have great holding power, and have never failed me. I can't believe how long the pads last. They squeal just a bit, but you can hardly hear it over the noisy engine and prop.

    Strengths:    what? Strengths? Nope none.

    Weaknesses:    well, they squeak for about an hour then stop for 6 seconds then squeak. The return springs brake easily. the pads wear easily. And, they just dont stop that great.

    Bottom Line:   
    the brakes that i got cames with my bike. i dont know if i got a faulty pair or not but a lot of people like them. im not one of them. I would recomment them for a beginner who needs disc brakes but dosent have the beans for hydros.

    Strengths:    They stop you dead, on the braking front what more do you want????

    Weaknesses:    That effing squeal i go cycling all day some times as long as 16 hours in the peace and quite of the countryside and its the last thing i want to hear. I clean with meths and sandpaper which if i do it often enough it reduces the problem ie its not a constant but i could really do without it. PS no problems with setup.

    Bottom Line:   
    They came with the bike wouldn't buy them again unless i could solve the 3 little pig noise. Excluding that i can see no reason to buy any other disc brakes ie if they stopped me any quicker i would part company with the bike. Not done a lot of major downhills but sometimes they feel like there going to give up on really long downhills they never do and i think its a cable problem anyway. Note these were the recalled brakes and i had no problems getting the replacement despite buying at auction.

    that was the last time I wrote here... there are more than 1 year and a half and I DIDN´T GET ANY NEW CALIPER FROM THE RECALL MADE BY DIA TECH. If you care about your life, stay away from this. If you care about money, go buy some V-brakes cuz I guarantee you that they work better than DIA TECH SPIRAL STOP. I DIDN´T RECEIVE ANY CALIPER FROM THE RECALL NOR A WORD FROM DIATECH ANYMORE. At least I´ve learned that if I have to buy some thing, I gonna buy from a brand that I can trust.

    just came back from killington ski resort,hate to say it but my diatechs are hurtin,a few hours of downhill fun cooked the roters.they sure dont stop like they use to either,I changed the pads, cleaned em up with alcahol, all the usual stuff,but they just dont want to bite anymore.a friend that went with me rented a bike at the mountain.the rentals all have avid mechanical disc brakes.I tried his rental out and was blown away at how much bite the avids have.he rode all day on those avids with no problems.my diatechs were great for all the xc riding i do.......but downhill stuff just killed em....

    Strengths:    Ease of operation -
    Stopping power (I weigh 230)
    Nice modulation


    Weaknesses:    Sticking problem (taken care of with new calipers)
    Needs to be set up with new levers (my was set up with Avid 1.9's) Does not provide enough pull.
    Need a conversion or adaptor kit to mount on Manitou forks


    Bottom Line:   
    Like many, I was unfortunate enough to have the recalled calipers and had the sticking problem that was so often occuring. I called Diatech and talked to Eric Schreiber and he quickly took care of my problem - the customer service on this was un-paralleled by anybody in the industry. I have two brand new ones on the way. Other than the sticking problem I had the brakes worked very well for the type of riding I do.
