I have a 2010 Trek Madone, 3.1 with the original 11-28 cassette. how often does this item needs to be replaced?

Depends entirely on how much you ride, and how you ride. Other factors include riding conditions and how often you replace your chain. Only an experienced mechanic can help you determine when your cassette needs to be replaced.

it has been about a year so I can't remember too many details...except to say that the two pedals are not both "right-handed" screws on unicycles / bikes (so that they won't automatically loosen w/ use). Try to tighten (by hand!) the other direction. To answer the support question, probably no where available, and I'm not even sure it is "M Wave" b/c ours says "FUN" as the brand!

I haven't had to deal with that issue. My bike has been doing great! I would send a request to Schwinn for the information.

I used 8 speed cassette, I did not install 7 speed cassette, I know it will fit, sorry I do not know too much about cassette, I am familiar with cluster for over 40 years.

all that matters is that your highest gear is lower or equal to your highest tooth count for your derailleur. if your derailleur can take 32+ teeth, then you're good! the low number doesn't much matter, but having one less tooth means you can go a little faster. Most derailleurs these days will take more than 32 teeth. if yours can't, then you can just pick up a new one for about $20-50 depending upon what quality you want. you might also want to change out your chain if you're changing your cassette, just to make sure you don't stretch your new cassette, and keep in mind you need a cassette lockring tool (7 bucks) and a chain whip (10 bucks) in order to change out your cassette -Peter

11-36, 12-36 gearing is typically for mountain or cross bikes. If this is going on a road bike, most likely your derailleur is too short and will not work with the the larger gears. Most road cassettes only go up to 28t (and that is probably the max a "short-cage" derailleur can take). If you want easier gearing, go with 12-28t, compact chainrings in the front, or get a med-cage derailleur to handle the 12-36.

You can use the newer version provided the gearing is the same. I used this Sora to replace a Shimano shifter from the 90s so I am sure it would be fine to upgrade an older version of Sora (again, provided you are using the same number of cogs on you front crank and rear cassette).

I also need help with the stripped pedal. It has fallen off. I need to get this fixed soon. I use the bike every day.

It depends on your chain, the brand and and how old that 7 speed cassette is. The width of chains have changed over time and just installing new gears can be problematic as a consequence of both the change in chain link sizes as well as the consequent changes in derailleurs. Hard to say. It will probably work in a pinch but the only way to be sure that your entire drivetrain works in harmony, you kinda need a complete set (cassette, chain, chainrings and sometimes even derailleurs and shifters if you're changing component generations).

I just recently replaced my motor and have not had any issues so far. My initial motor still works, however, it was the gear box that crapped out .... lasted about five years and begin screeching and grinding (gears wore out ... unfortunately you can't find a kit to just replace the gears). So, I have a backup motor now.

Usually cassette sizes 7,8 & 9 are compatible. It's a newer bike so I think you should be fine. Remember if you decide to switch the speeds on the bike you're also going to have to switch the shifters if they are not compatible to the speed...

It's been some time since I replaced the shifters, but I believe you will use the bike's old cable housings and just thread the new cables through them. The cables come installed in the shifter mechanism and are plenty long so you will need to trim them once they are installed and secured in the derailleurs. It's a pretty easy installation unless the cable housing is corroded or damaged. Good luck.

None that I know of. The t stands for teeth so no need to worry.The cassette works just as good as any Shimano...

I used these to replace the shifters and cables on my Trek 4300 mountain bike. I completely removed the old cables from the bike along with the old shifters. These new shifters come with the shift cables attached. I reused the cable casing that was on my bike, applying lube to the inside of the casing before threading the new cables through. The installation of the cables was easy. The adjustment to the derailleur after the cables are installed is a bit tricky. The best I can offer on that process is to either research online, find YouTube videos, or take the bike to your local bike shop and pay them to make the adjustments.

HelloIm not sure how long it is... I just put a new one in my bike every 4 years

I would replace it with exactly what's on it now. The 8 speed might fit but then you would need everything else to be compatible.

Dear Juice: There are two systems. One is the older-style freewheel where the cog unit goes screwed on the hub of the rear wheel. This Shimano Tourney is one of those screw-on cogs. The newer system is where the cog unit -called a cassette- goes pushed and then locked on a splined extension of the hub. Both systems are not compatible. My advise is get a bike mechanic or a friend who knows the difference between the two systems have a look at your bike and tell you which system it has before you spend the money :-) Hope this helps, Andy :-)
