Hey Biker Kid,
I use avid mechanicals and have been since the very first version. I have two sets now. Low maintenance and low tweaking frequency. I had an initial Hayes Mechanical which was recalled. It was a piece of junk as it would lock up...Yikes. That one gave me a few scary drops. I sold the hydraulic they gave me as a replacement as the Avids had just been produced. I ride them year round..snow, mud, rain, etc. Also, I live down in Orem, UT. Welcome to the list. Do you ever post on utahmountainbiking.com?

I've heard that avid is one of the best brands for disc, mechanical and hydraulic.

I haven't posted on Utah mountain biking yet, but I am going to register. I have also been on the website a few times and gone on some of the trails listed.

Looks like you found your set-up - eh, I'll thow in my 0.2 cents anyway, I prefer mech over hyro...hyros are a bit to powerful for my liking, I like something with a little drag to it.

I am looking at bb7s because they are higher quality for only a little more money.

Go with the BB7s. The BB5s have only one sided adjustment per brake. The BB7s has adjustments for both pads(sides).

I've sold disk brakes and have tried them all on my own fleet:

+ formula B4, B4R etc - lightest and most powerful - but they break very easily in lots of fantastic ways. very Italian.
+ formula ORO - at last, they fixed the durability issues - but they now have pad retention problems on many of the models! even more Italian.
+ avid juicy 3's, 5's: just avoid them unless you like squeaking.
+ avid juicy 7's are good, but mainly because they have more adjustment to solve the squeaking.
+ Magura's - hard to find nowadays, very powerful but they kept using brittle hoses!?!
+ Hope - very popular in the UK but I think they are a bit over-rated. the M4's look fabulous and work well.
+ Hayes - not popular in europe for some reason.
+ shimano XTR - avoid, totally non standard

shimano XT - the best all rounder disk brakes and cheap too - use a 203 or a 185 front rotor and a large rear rotor.

One of my biking friends has a pair of xtr dual control hydraulic disc brakes on his bike, I like the braking power, but it seems that as soon as you pull on the brakes they lock up, they also need frequent cleaning or else they will squeak. The shifting part of the levers is great.

thanks for the suggestions,
Bike kid

>bike kid,

the sharpness of the brakes (aka modulation) can sometimes be solved by using smaller rotors. A lot of guys go for the big 203 and 185 rotors but really don't need them.

Where I'm from (Scotland) my normal thursday night ride (its raining!) is up a hill thats about 1000ft climb from here with dropoffs and fast downhill sections with a lot of technical sections on the way home. Also, I'm 83kg, 6' or thereabouts, fat bastard according to the Nintendo Wii, and so need the bigger stopping power. I used to overheat my 160mm formula b4's until i went for a larger rotor.

actually, I did a movie on youtube of the descent. search for "Dumyat"

"...fat bastard according to the Nintendo Wii,"

Damn, Wii! Nearly threw that little handle thing through the window after my 12 year old daughter whipped my butt in boxing!!!

have to throw in a recomendation for Hayes el caminos....
really top flight, easy to care for and highly adjustable

bike kid · « **Reply #25 on:** August 29, 2008, 08:26:25 pm »

What do they usually sell for?

scottmartin49 · « **Reply #26 on:** September 05, 2008, 04:22:52 pm »

"bestbikezone" has them on sale for about $95 a wheel ; unless you really wanted to, you'd never need to upgrade, just replace the pads....

I have the money for disc brakes, I'm just waiting for a good deal on avid bb7's. I bid on a set for $56 and was outbid by a dollar.

jeffhop · « **Reply #28 on:** September 07, 2008, 08:32:48 am »

bb5 are almost as good as the bb7 apart from the outboard pad adjuster, same stopping power just need a little more care setting up but apart from that if you can get a cheap pair of bb5`s you wont be disappointed.

bike kid · « **Reply #29 on:** September 13, 2008, 08:30:22 pm »

Have you tried bb5's, or bb7's? From what I've read and what other people have posted in reviews, they say there's no comparison, bb7's are better.

Thanks for the replies,
Bike kid
