Strength:

braking power. Looks.

Weakness:

parts availability

I ran these brakes for 2+ years on my HT 29er. Absolutely loved the modulation and the power. This bike was my one-bike. It was NOT going down lift served terrain. But it came down 2k foot trail descents with flying colors. i wish these were still available. I never had any concern with trying to adjust lever reach (and hence wanting K24s). Easily my favorite brake of all-time (so far).

Got these on closeout at CRC. Something like 250$ for the set. Amazing deal.

Strength:

good stopping power, good modulation, light weight, good ergonomics.

Weakness:

strong heat buildup (esp. with 160mm rotor in the rear), very inconsistent lever feel, had to bleed the rear brake 4 times until there was no air left in it.

for that sort of money it's a great brake. but i've taken it off my bike and put on some avid bb7's instead.

Strength:

at first the back brake had a pile of power. look great. the front brake is amazing.

Weakness:

back one died after 2 weeks. origional pads are crap.

i bought them at christmas, the back brake worked for 2 weeks after that then all of a sudden when i was riding down a simple trail, i feathered on the back brake and noticed nothing happened, suspecting the worst, i pulled the lever in as far as it would go and it might aswell of been an accelerator to tell you the truth. this resulted in my feet being the brakes because every time i touched the front brake, the front wheel slid away from me. me and the bike ended up in the bush. when i went home, the brake was returned to CRC to see what the problem was... the seals in the lever were burst. crc fixed them. i got back on the bike, rode another trail - this time bombing it! half way down... suprise suprise!, it didnt work. i managed to get to the bottom of the trail and the brake was somewhat.. on fire. by the time i got home, the pad lining had broken away from the metal back plate. the back brake now sits in the bottom of my spare parts box. i dont know if i got a deformitive brake or i just got unlucky with it, but it caused a few promlems. on the other hand, the front brake works a treat! love it! id reccomend them because everyone else likes them and i just think i got unlucky with it.

Strength:

Great feel and stopping power.

Weakness:

A little finicky when it comes to bleeding.

My first real bike, so I can't compare these brakes to anything. But, I'm 200 lbs and agressive, and I've never been let down.

I have also pulled them comletely apart and found they were pretty easy to maintain. The replacement parts were easy to find. Bleeding them took a little effort with the small (easy damaged 0-ring), but it all came out good in the end.

IF I upgrade I'd be going to the RX.

Strength:

Looks good, good stopping power in most conditions.

Weakness:

The silver rod in the leaver pops out in most kind of crashes meaning the end of a race, major fault to the break.

These are good if you are a rider that never crashes and rides xc on smooth trails. If you are going to have the odd crash i would stay away from these. I hope to sell these soon and go back to hope mini's.

Strength:

Lightweight, Italian, modulation, maintainance.

Weakness:

Sounds quiet allot if not properly calibrated/tuned.

This is the second time I go for the same set of brakes, how ever white powder coating this time. While braking them in I push them until Purple-Brownish. No power or modulation fade and the brake discs are still absolutely straight. They can cope for what you trow at them.

Strength:

Excellent stopping power, unreal modulation, light weight, quality second to none.

Weakness:

Somewhat difficult to bleed - there is an updated "how to" bulletin on their site now that helps.

I'm very confident that these are the best brake for the buck that you will find. The make the Avid Juicy line look like a total joke! Rarely any brake noise and the K-18's share the same caliper as the more expensive versions in the ORO lineup so they have the same superior stopping power without all the bells and whistles.

Did want to comment on the one poster who gave it a 1 because the lever pin fell out; Formula had a recall and that problem was addressed. If you are unsure about yours, call them with the serial no. and they'll send out the updated pin kit free of charge.

Strength:

Cheap, great stopping power, good modulation.
Easy too bleed.

Weakness:

Had a leak in the rear piston. It was easily replaced.

Great break for little money.
I would have settled for the 160mm rotors for my quite tough all-mountain riding and my 65kg of swedish flesh and bone. 180mm offers alot more than I can ever use.

I would have given them 5 chilis if they hadn't begun leaking.

Strength:

Great stopping power. Modulation feels great not like any other brakes (xt) ive had! u can feel the brake working rather than just on/off.

Weakness:

Not really a weakness but theres better pads out there than what come in the box. cant complain tho. I did the whole 2007 winter and never had any trouble.

It took me over a year and almost a releationship to build up my dream machine not cuttin any corners on parts. Thease brakes R in my opinion the dogs bollox! I wouldnt av um if I didnt think they were! No trouble with maintaining them and they could stop a race horse! There not even that expensive anymore! Seen um on merlincycles.com for about £140 a pair!

Strength:

Amazing power using the 160mm rotors. Standard Formula pads aren't great in UK riding conditions but a switch to some quality sintered pads and the power is there whatever the conditions. Lever feel is superb - not just off/on like some brakes, you can actually feather your braking. When you need to stop, you will. These inspire confidence and you begin to leave corner braking to the last minute because you know they will bite if you need.

Weakness:

They are a bugger to bleed... Especially if you lose the bleed nipple o ring! It's tiny. Be careful.

Well, that's it. I'm converted. Will certainly be buying Formula again if and when the K18s die. Just put a 180mm rotor on the front and the balance is perfect.

Buy buy buy!
