J   Racer [Sep 08, 2001]
Strength:

adjustable, anodized and stainless parts, compatability with frame

Weakness:

million and one parts, setup

The bottom line...I have raced semi-pro dual slalom for two years and have never dropped a chain. I have the AC Pro designed specifically for the LTS/STS frame. If the chainguide ever does fail though I will replace it with a different product. It requires too much maintenance, setup is difficult if you are not familiar with setting up your own bike, and best of all it sounds like you are dragging a million cans behind you on every ride. At least the other guys know when you are coming and to get the heck out of your way. I know that they know offer a "free" insert upgrade to make the upper guide quieter but I don't think that 10.00 for shipping two pieces small enough to fit in an envelope can be considered free. I think it's a little too late for mine anyways as the chain has worn the upper plate almost paper thin. Yes, it is set up properly. I think that AC finally figured out that a chain repeatedly rubbing against something as soft as aluminum is prone to premature wear and tear. I do recommend the red loctite when setting up and my Sachs chain has lasted longer and ran smoother with this system than any Shimano one that I have tried. I do have to give props to AC for designing such a sexy/complicated guide for the GT frames. For intended use and reliability, 5 chilis. For the headache of setup, maintenance(attracts mud like white on rice), number of parts, and the unhelpful and rude sales/tech individaul at AC(you know who you are), 0 chilis.

Strength:

Looks sweet!!, Lighter than others, It works!! Quiet if you get the upgrade.

Weakness:

Nothing

There are some tips to getting this thing to work correctly. Firs, locktite every screw before you even install it, and go to any hardware store and pick up a heavier spring. Plus, for all the people who complained about noise, all the new models come with teflon/nylon impregnated upper guides, and they are a free upgrade for the older ones. They run super quiet now.

Strength:

It works....

Weakness:

A/C has no website ??

It took me a while to set it up...i ran it with the top only but chain came off--so i put on the lower...have to zip tie it -because i had to put "stopper deal" on left side of lower guide so i could move the thing OUT more...i think it will work good....

Strength:

looks cool like you are a hardcore dh rider, when in fact i am not. works good. good lower spring loaded pulley guide design.

Weakness:

a B1TCH to set up! you have to have the right bb spindle width, it should come with other spacers for the upper guide. or i didnt get any extra spacers. whatever. loud too.

i didnt like how incredibly difficult it was to set up. with an mrp you just bolt it on and ride. this thing had multiple adjustment bolts and sleeves and what not. my chain kept rubbing the upper guide and getting caught in the upper guide. you cant backpedal or chain suck will occur in the guide. i never heard of that: guide chain suck! well thats just what the AC is. it, all in all, sucks. it works only sometimes. they should give you extra spacers for the upperguide so that you could size it correctly instead of having to buy new bottom brackets.

Mr. Extreme   Downhiller [Jul 01, 1999]
Strength:

It has a lot of strengths after trying to set it up and then having my local bike shop set it up they got it on. After a little fine tuning the noise went down. No matter how big i hucked it off a drop of a jump the chain never fell off. Even after flying into some 4 to 6 in rocks and roots it still didn't fall off.

Weakness:

The bottom part of it rattled loose and went straight down at the Mt. Snow opener this year. I had a guy at Monster Cycles work on it and he said it was stripped. He was trying to get it tight but broke off the bolt. So we took off the bottom part and still it stayed on, except for when i crashed. sent it back to AC to have them replace it.

very good if you can get it set up right, very durable, your chain will never fall off, have someone who knows how to do it set it up. would give it 5 but it broke

Richard Utting   Racer [Mar 30, 1999]
Strength:

keeps the chain on whatever, no flex/crashproof, quality construction, adjustability

Weakness:

price, rattles (but don't they all).

Bottom line: keeps your chain on, but you'll be lucky to get it silent. I mean, it physically holds the chain on come what may. If a chain device doesn't rattle, then the first time you ride in anger or crash, bye bye chain. So everyone shut up about the rattling, set it up real close to the chain and forget about deraillments. The sprung bottom guide is a nice touch and helps keep things running after bashing into rocks etc. Well thought out equipment.
