Strengths: It looks pretty and has the Shimano name printed on it.
Weaknesses: Poor design, does not perform in the field, on the road or anywhere outside of the showroom.
Bottom Line:
This bike is brand new with the Shimano Avilia shifter on this 8 speed, Puma- Biomega mountain bike. Within days the shifter vibrated itself apart. It virtually disassembled itself in a matter of traveling about 10 miles on dirt roads. I tightened it when noticing it's missing shifting gears.
Today it fell into 5 pieces on the road.
It's impossible to reassemble without owning a surgeons or swiss watch makers black bag of tools.

Strengths: good alloy mount, adjustable barrels, precise upshifts
Weaknesses: fails to engage ratchet for downshifts
Bottom Line:
I never had problems with Shimano's Rapidfires until I got this Alivio model (SL-MC40). It's pawl slips past the ratchet teeth frequently, and the thumb lever has poor torque. Yet I have an 8-speed STX-RC shifter that is still flawless after 12 years of commuting. I also had an old Altus model (with the unified thumb/forefinger trigger) and it worked very well. So in my case, this mid-grade Alivio model was outperformed by its cheaper, reliable Altus cousin.
(Attempting to repair the Alivio made everything loose and weak, although it indeed eliminated the blow-through shifting problem.)

Strengths: Just as good as the Shimano Alivio Brake Levers.
Weaknesses: The screw head stripped when installing a new handlebar.
Bottom Line:
Same great quality shifters as the Shimano Alivio brake levers. Great while I used them from mid Oct.1996 to mid June 2004. Bottom Line: While I had them they were great and worked flawlessly.
Purchased At: Stock on my 1996 GT Ricochet - D'Ornellas Bike Shop

Weaknesses: Cheapest plastic,they really dont work if you want them to do anything wright
Bottom Line:
These are greatest shifters on a planet!!!! P.S;these statement is for people who have their bikes in a garage,and once a year on a shiny day they pull em out and ride few hundred meters on a straight asphalt road in company of retired 75 year olds who just have their first bike-ride in life

Strengths: Works well with shimano 8sp components - last long under harsh conditions and a billion times of gear change .
Weaknesses: Dont open the bottob cap or meddle with it or all the parts will become loose and will not operate properly.
Bottom Line:
I used it 3 years on my XTC shifted with it every day 24/7 and didnt came along with it . pressed the knobs hard while mud didnt let my chain to move .Changing 5-6 cogs in half a second during races.they were great But dont open or meddle with them just leave them as factory set.

Strengths: cheap
Weaknesses: Doesn't last, sometimes doesn't catch.
Bottom Line:
I thought Alivio was supposed to be a step up from Acera and a step down from Deore?? These Alivio shifters are junk! I can't believe that after less than 500 miles on a new bike the left hand shifter half the time won't catch to upshift to the largest chainring! I've got a pair of Aceras that have lasted for 5000+ miles and not given me a bit of trouble. I'll certainly never opt for anything Alivio again.

Strengths: they lasted a kinda long time, almost 2 years but nothing special, they sit under the bars so when you lay the bike on it's back it doesn't hit the ground like a deore shifter (my right side shifter)
Weaknesses: well,,, they fall apart, the shifting sucks and requires more pressure than say most shifters i've tried, feels whimpy and soon enough becomes whimpy and falls apart like my schizophrenic couzin.
Bottom Line:
if you have one and you like it, good job, but don't do anything bumpy, harsh or any big hits if yours still hasn't fallen apart yet your not trying hard enough, i went down some rocky and bumpy downhill slopes when i got to the bottom my right shifter had disappeared except for the clamp, then i had to go up hill and downhill for 1 month either in 2,9 or 3,9 gear, that was not so fun and finally i got my deore shifter and it has worked great, shifts better and doesn't die, i can feel my left shifter starting to fall apart, it's just moments till it dies then i have to get another deore or maybe i'll just switch to sram x-9 shifters and derailleurs.

Strengths: pretty simple, wont break like deore,lx, XT will if you fall. its because the shifter sits on the bottem of your bars, instead of the top. good feel.
Weaknesses: a little chunky
Bottom Line:
I think this is the best option for 8SP. these came on my bike, but even if I got a 9sp setup on a bike, i'd swap it out because an 8sp will give you less problems. these are simple and i'd trust them on any bike.
Strengths: easy to use. don't fall apart when im doing stair gaps.
Weaknesses: heavy (not like i care). ugly (not like i care). sometimes the lever the lever that your index finger pulls gets in the way when you want to pull the brakes (that can be easily solved by just moving it over a little)
Bottom Line:
overall good. but you might want to take others into consideration first.

Strengths: Nothing
Weaknesses: Everything
Bottom Line:
These things suck nuts. Shortly after getting these the caps fall off the bottm, dust gets in and the shifter levers stick when shifting, so when u shift once and have to shift again u gotta pull the lever back up. The springs fall out of the bottom sometimes and when they do the shifter shifts like sh*t. These shifters make the chain skip. DO NOT buy these shifters thinking they r a high end part they are not. I wouldnt recomend these shifters for anyone except for like a begginner turbo spandexi (xc). If u buy these and u r a freerider these things will make u punch a cat... lol
Bike Setup: 2004 Norco Rampage, rear 26" double track, double e backplate, deore rear derileur.

Strengths: -Look Cool -Work well -Cheap -Nicest 8 speed shifter in shimano's 04 line
Weaknesses: -Heavy (not that I care, but you might) -I broke it
Bottom Line:
These shift as well as any other shifter. Cannondale put an 8 speed drive train on the chase to be able to use the beefier 8 speed chain, and save money. I broke of the dust cover on the bottom the first time I hit it with my knee. I put it back on kinda, then I hit it again a day later and it fell off again, and a spring fell out too. Now it doesn't work. Otherwise these shifters worked fine. Maybe if you don't hit them they won't break. Still I hit my old XT's hundreds of times and they were fine. I think I'll try to find an old XT shifter pod set with 8 sp. These are still good shifters though. umm, I gotta go

Strengths: they shift amazing, and you can downshift 4 at once, look pretty sweet
Weaknesses: kinda in the way when you are holding onto the grips, but i just moved it down the bar.
Bottom Line:
i dont think i woulld trade for any other 8 speed shifters, they feel good, can shift your gears like an angel, and are not too expensive. a great shifter for anyone.
