Strengths: Consistant performance. Will provide more power then XT V in 6 inches of wet grass
Weaknesses: Consistantly B.A.D. performance. NOOOOOOOOOOO Power
Bought on sale, should have come with front hub but it wasn't there so the did me a deal on a new front wheel. Got home and found that the Rotor didn't have a Standard 6 bolt pattern, back to the shop, found me a Deore front rotor (same thickness and diameter but smaller swept area). Mounted it and put the cable on. Easy to setup, did 40K+ to break it in of constant stop start single track stuff wasn't happy with the feel and then rode it to work.
Have to come down a really step hill, constanly on brake to avoid traffic. Nearly didn't stop at bottom no matter how hard I pulled on the lever. Smoke off the brake and I think I saw a small flame, the rotor got so hot it turned purple. Took it back to the bike shop, they were scared at how bad the brake performed so they sold me an Avid mech for about US$50.
I bolted it on and without having worn in they would give me controlled front wheel stands with little effort from two fingers.
Listen Carefully, "Buy the Avids, Young Jedi Cyclist..." cause the Diatechs scared the mechanics...
PS The Avids weren't hot enough to stop me from touching the caliper, I discovered, when I went to adjust the pads at the bottom of the big hill... much better
Bike Setup: Gary fisher level betty done up for downhill

Strengths: Still have brakes if you bend the rim. Anti-lock.
Weaknesses: The anti-lock isn't ment to be it just is on mine(cuz they suck. These suck. They have no power, my 6 year old mongoose with cantilevers has more power. They squeal like a pig. If they get wet you dont have brakes anymore.
What a waste of metal these are, just don't buy them.
Bike Setup: '99 Marin Rock springs(Marin I'm disappointed that you put these on your bikes).

Strengths: Cheap - I guess. Excellent customer support from Diatech.
Weaknesses: Even after the wearing in period these brakes were a real dissapointment. The cantilever brakes on my old rigid Pacific XT were superior to these! The rear brake has never at any time had the power to lock up the back wheel. These brakes have alsways rubbed and the floating calipers do not appear to 'float'. The front disc warped so severely on the first proper down hiil that it forced the caliper bolts onto the spokes! Diatech customer support were very good and sent a replacment front disc quickely. However, after several trips to my local bike shop to try and give these brakes some decent stopping power they are still inadequate and I have given up. These brakes are about o be 'retired' in favour of some proper Hope disc brakes.
Brakes are important!! buy decent ones that work properly!

Strengths: Initially, after bedding in, it was good, but...
Weaknesses: it hasn't stood up to the test of time. I fel an Avid Mechanical coming on...
OK. If you look below you'll see I've given these disks a fair bit of praise. I thought mine was fine after I'd shown it the proper respect. But my bike is now nearly two years and the brakes with it and they're failing me.
It USED to be better than my Avid rim on the rear, it is now embarrasingly worse. My local tech guy says the pads are not worn, despite their age, because I mostly use my rear V. He says they're just crap, and I'm beginning to agree.
The other day I had fifty metres to stop going downhill on TARMAC at 25 mph approx and I had trouble stopping, this is in the dry.
The Avid mechanical is the way forward I think. It's now very cheap and I'm getting it, you'll see my review soon enough. As for these, I think you should not have to go through a products lifetime having to tinker with it endlessly for better performance than the standard, which by comparison isn't very good. Ho-hum...

Strengths: None that I can see
Weaknesses: Where do you start?
These brakes are completely useless. Do NOT buy them. If they are on the bike ask for them to be changed. I've followed all the instructions on the Diatech website and still they are pathetically weak. Any set of V brakes will have lots more power than these pieces of junk. I'm going to bin it soon and try an Avid mechanical disc.
Strengths: Extremely cheap and simple enough that a drunk monkey could figure out how they work.
Weaknesses: The don't stop well at all (even after wear in period), very difficult to get running drag free, they are cable actuated, cables should actuate cantilevers, not disc calipers. The "floating" caliper doesn't float, even when we've worked on them a ton.
Do not buy these. Do not accept them if they are given too you. I do not wish these brakes on my worst enemies. They are very difficult to get working correctly after you have put any miles on them. They are not powerful at all, they will not live up to your expectations, if you have V's, stick with them and save your money to get a sweet hydraulic setup from a company that knows what they are doing like Hayes, Magura, or Shimano. You won't be dissappointed like you will with these.
Purchased At: I'm a mechanic, I didn't buy em, but I've spent much time working with them.

Strengths: satys clear of mud, front brake good
Weaknesses: rear brake needs "grip of iron"
These brakes seem OK, but the rear needs a big handful to slow you down. when I got the bike, it was so weak it was impossible to lock the rear wheel - even my 9 year old son's bike could do that! However, after a good 3-4 hours of tinkering, and speaking to El Marko at Dia Tech,and changing the rear and front pads around, the rear is now much better, but still not as strong as I would expect. I have ordered some "green pads" from my LBS and hope that they will make it better on the back. The best bit is the clearance from the mud - last time I was out the mud was inches deep, and the guys with rim brkes were struggling, so at least the performance is consistant. The front is so much better than the rear, I went over the bars in graceful slow motion when I grabbed too much front to avoid a chain that a kind land owner had fitted across the track! Overall, a good front brake, but slightly disappointing on the rear. I'll persevere though, as I hate to be beaten by anything mechanical.
I'd recommend these brakes to someone who likes the idea of discs, but doesn't want to mess about with hydraulic fliud and can't afford the price that Hope etc. charge.

Strengths: It has awsome stopping power with the green pads i bought. They are easy to adjust and stop on a dime and seem to get better with time(I`m a poet and i dont even know it)
Weaknesses: They are a piece of junk when out of the box, so straight away i changed to green pads and boy do they bite.
There a great value for money brake with a heap of braking power, and have a better feel than hydrolics because they dont just lock up and rip at ur disc ( us moto riders would know)! and i recommened them to any cross country rider and four the light downhiller
If u have the money go for Shimano dual piston calipers they fell awsome cause i just got one!

Strengths: looks ok
Weaknesses: the disc bends very easily and it dosn't work very well.
I have tried every new type of pads with it but its just too weak so im saving up for some Magura HS33. The V on the back is better! you shouldn't buy it if you are a trials rider but its ok for cross country.

Strengths: easy to look after, keeps itself very clean, sexy looking, cheap as buggerey
Weaknesses: rear has no stopping power, fad very fast
started out great but then the rear really started to suck, I tried everything, new pads, stronger cable, bigger balls, nothing worked so I threw a set of LX's with xtr pad's and now I'm laughing. The front has been alright, alot to do with length of cable I think. Tried a set of hope's on another bike just to see the difference,, sex on wheels if you got the doe that is, if you an't got the doe then these will do.
Bike Setup: Marin rock springs, now with LX v's on the rear, so I can live to see another day

Strengths: Simplicity of design,stopping POWER(!!!),excellent modulation(its not all or nothing,they actually have alot of"middle")they seem to get better the more I ride them!
Weaknesses: You must be patient and break the pads in!A couple of easy rides and that will do it.
I did my homework ,as this is my first "real " mountain bike and was surprised to here about all of the troubles these brakes have had.With the info in my hand and the trials and tribulations of others in my head,I set out to follow every suggestion given to me.These brakes have earned my trust and respect after I got them dialed to where I like them.I am 240 lbs. of x-football player that can descend stuff ,that I sometimes wonder if Ill survive,with full confidence that I will stop when I need to.These are vastly superior to v's and wont just lock you up and send you out of control.They actually have a smooth "power band"to them.(anyone who rides motorcycles "knows" what Im talking about.)Final thoughts? Set them up rt., take your time and burn in the brakes,clean & lube them and they will never fail you.I personally love them and trust them with my life.(every time I ride!) PEACE!

I just got the new calipers from El Marko. I must give him props because I haven't totally broken them in yet and they don't stick, have better brake modulation, and much better stopping power than the old calipers. These brakes work so well, they can actually through you off your bike if you lay into them enough. I do not think I will ever be worrying about not having enough stopping power under any weather conditions. El Marko contacted me through my review and within a week later, I had new calipers and excellent setup instructions. Its a rear occurance for a company to treat their customers as well as Dia Tech has. I must give this company an 'A' for customer support and satisfaction. I would recommend this product to anyone who wants to upgrade from their 'V' brake system.
