Strengths:    They work, better than most V-brakes, not too heavy, and cheeeap

Weaknesses:    hard to find pads for, but might as well buy a whole new caliper for the price.

Bottom Line:   
Used them on my hardtail for a while before getting my FS. Got avids and like them better, if nothing else just because I wore one pad out to the metal, couldnt find replacements. Did have an issue with the pad adjustment scews re-adjusting themselves, drop of blue loctite fixed that. Avids are easier to adjust tho, with the big red dials on both sides (little black plastic adjuster on these also liked to turn itself). One thing I did like was that the external adjuster thingy moved the whole caliper, and the caliper kinda "floats" where the avids are fixed to the frame and you have to adjust the pads individually.

Strengths:    Simple to set up and maintain. They don't fade much.

Weaknesses:    Can't be used on 74mm Manitou forks.

Bottom Line:   
Unbeatable for the price. Work really well on the rear with 140mm disk. I am going to have to get a different brake for the front as the other Grimeca I bought wont fit (make me an offer). I will be a able to compare then. On the whole I am really happy with these.

after break in period they work excellent.
easy to adjust. i can't imagine avids mech. being any better.


Weaknesses:    a little noisy untill broken in. so what


Bottom Line:   
i paid a c note for pair brand new so i'm giving 5 flaming turds. had i paid the 200.+ list i would expect slightly more stopping power.i'm hopping getting replacement parts won't be a problem. but over-all i'm very pleased with the perfomance of these brakes.

Strengths:    Strong, simple, durable.

Weaknesses:    Not brilliant stopping power, weight

Bottom Line:   
As I work for a certain famous bike retailer I got this bike at a very reasonable price when I was looking for a bargain freerider, but accepted that the component mix didn't do the frame package justice.

I've changed just about everything except the cranks and these brakes.

I probably would not buy them seperately, but with this bike they have performed excellently. For most recreational riders they will be more than enough. Need a bit of careful bedding in. Good strong cable housing.

Not the performance of my Avid Mechanical disk on my Marin and a lot heavier- these disks are too beefy for a lightweight XC machine.

On the whole, great value for money.

Date Reviewed: January 30, 2001

Strengths:    Once set up, they are eyeball-poppingly effective, and are no hassle in the wet, compared to my old LX V-brakes. Despite rumours, pads are easy to get hold of.

Weaknesses:    Product came with Bike, so the manual was on the internet, which takes a year to download. Setup took a while, but once I'd worked them out, I was happy.
Levers are cheap, so bought some Deore ones instead. Disc attatches to hub via 5 bolts, which may raise compatibility issues.


Bottom Line:   
Came with bike, so I don't know how much they're worth, but in comparison to my old brakes, they're excellent, especially in the mud. Very sensitive, with plenty of modulation. Give reassuring feel at tricky moments. Now I know how to set them up, they're a doddle!

Elixir 7 - Air in system

I bought a set of used Elixir 7 brakes and can't seem to get all the air out of the front brake. I've bled the brakes at least 3 times now. I'm using the Avid Pro Kit and am pretty certain I know what I'm doing. My bleeds have been flawless on the rear brake and my other bikes. The issue I have ... Read More »

avid elixir 7 - closed system?

My elixir brakes have that adjustable lever position. But this position seems to move depending on fluid temperature (volume increase with temperature). As soon as i start using the brakes heavily, the lever moves outward, away from a comfortable position. One more reason to ditch them... well, does ... Read More »
