Strength:

As brakes I cannot say this product has any strenghts, however they might make a nice pair of paper weights, or a matching set of ornamental anodized aluminum things to show your uninformed friends.

Weakness:

This product does not stop your bicycle wheels from turning.

These caliper type fixtures cannot be called brakes. Brakes need to have the primary and absolute essential function of being able to STOP a wheel from rotating. These Grimecas might be very nice other things, but certainly one cannot call them brakes.

I used this product for less than one month and rode on them for maybe fifty miles on XC trails in Northern California. I waited for them to "break in." The waiting was in vain, since they just don't work. Poor all around design and possibly a hasty effort to get these out on the market makes these the worst possible excuse for brakes that one can possibly imagine.

I cannot recommend these to any mountain biker.

Strength:

Price

Weakness:

Pig to fit
sticky pistons
sticky levers

Good price but should haved saved up for better.

Absolut pig to fit with the kit bolts to long and will rub everything in sight. Cut off excess threads, filed down the heads.

Front
Pistons always sticking out - good for training but hard work

Back (now functions as car handbrake)
braked do not come off - had to push lever both ways - pulll for on, scracth head, pick nose, push lever for off - quite handy actually.

get some hopes

Strength:

None!!!

Weakness:

They are the worst set of brakes that I have had. They came with my KHS 2001 FXT Comp. The first couple of rides were great, good stopping power etc. Then came time to bleed and service them. They are now spongy, unadjustable. One of the bleeder nipples snapped inside and Grimeca would not even reply to me about spares. Contacted KHS and they do not deal with Australian customers. $3200 AUS I spent on the bike and the brakes do not work. The bike is only 8 months old and has spent more time in the work shop trying to fix the brakes.


Happy Trails

So these brakes are not worth the price of half a can of coke. Go the Hayes or even the Avid cable disc. The later is my new choice after reading the reveiws.

Strength:

strong disc, braided hose is a rarity at the retail price... errrrrrr, they work?!

Weakness:

overall heavy, hub needs servicing before it can even be used!, lots of drag, the brake feel could be better, awful lever blade. the bleed nipple is the worst bit: mine snapped off when i was tightening it up and had to be drilled out + repaired.

well theses brakes are very good for the retail price but there is so many little problems with them, like the weak snappy bleed nipple, and the slightly excessive drag, and the awful lever blade. also i know the hub is optional to be used but if you do use it i strongly sugest you take apart the rear hub and apply alot of grease to the hyper-glide as otherwise it can start to slip. overall if you realy must have hydrolic disc brakes and you cant possibly afford anything else, you will get along fine with them.

Kevin   Cross Country Rider [Sep 11, 2001]
Strength:

Braking good to start with.

Weakness:

Heavy on Pads. Front brakes went spongy after 3 months, broke bleed screw while bleeding. Rear failed after 13 months locked on during downhill.

V brakes may not be as good at stopping but they are more reliable, cheaper and easier to maintain.

Jon Smillie   Cross Country Rider [Nov 19, 2001]
Strength:

Excellent stopping power and lever feel.

Weakness:

Very fiddly to bleed. Seem very sensitive to setup/adjustment. Stock pads seem to be unreasonably squeaky.

These brakes came as original equipment on my KHS duallie. They needed to be bled after the first ride, and it took
several rides before they bedded in and started working at maximum strength. Bleeding is not complex if you know how to
bleed other hydraulic systems like car brakes, but it's very fiddly due to the small reservoirs, and you need to be careful with the delicate bleed nipple and the screws on the reservoir tops. After this was done though, they have worked
flawlessly ever since - very smooth and powerful.

My big complaint is the frequent sqealing and very occasional chattering. They seem to be very sensitive to initial setup of the calipers - you need to ensure, via fitting shims etc, that the pads contact the rotor squarely
or they scream like banshees. They are also very sensitive
to contamination or glazing of the pads. They seem to readily develop a constant squeak when they are disengaged,
although as soon as you apply the brake they shut up. I've
found that removing the pads and rubbing them down with fine sandpaper makes them silent again, but after two or three rides the pads are glazed/dirty again, and the squeak comes back. I think it would be worth experimenting with pads, maybe going to a softer compound.

I'd give five stars all round if it wasn't for the noise. They work really well, but I've found the squeaking at times
so annoying that I'd go back to cantilever brakes just to be
rid of it sometimes.

They just need to much adjustment and attention.

random bike guy   Cross Country Rider [Apr 29, 2004]
Strength:

red
when they work, they work well

Weakness:

hardly ever work like they should
rub
slack levers

these brakes work when they want to and when they rub, the wheel doesnt spin at all, but after a service they work brill, but when stripping them, you must use rubber grease or else you can damage the seals and totally break them, which i feel like doing sometimes, but after a good service, they work brill, especially with sinted brake pads, but if i were you, ide get the clim8 6 pot, they just kick ass and there cheap..buy em!

Strength:

Stop really good. Great for tricks. Worked great right away.

Weakness:

None so far.

These brakes came with my bike and they kick ass. I am now looking to upgradr my rear avid linear brakes to these. They are definitley worth buying and if they come on your bike even better.

Martin Ocando   Weekend Warrior [Feb 01, 2001]
Strength:

I bought this one as a set, including grimeca hubs and Vuelta excalibur freeride wheels. It has excelent modulation and run drag free. Comes completely bled out of the box.

Weakness:

Takes a little break in time. Bleeding is messy (I've ordered the bleed kit to fix this). A little expensive down here, maybe cheapper in the US.

It's an amazing piece of brake, great modulation and power. I had to switch the front rotor from 160 to 180mm to reach the caliper using the manitou adapter, but this improved braking power. Stops in a dime.
