Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Tiagra shifters are garbage

I got a new road bike and it has nine levels in the cassette and I can only shift back and forward with the bottom 4 levels.

what the hell?

Aren't you the same one who posted about his pump not working with Presta valves?

Your rear derailleur is not properly adjusted. This is probably not a shifter problem. Who built your bike out for you? Take it back to them and have them do it right. The cable is not tensioned properly in the RD, or the limits are set wrong.

Tiagra shifters may not be as good as 105, Ultegra, or Dura Ace, but they aren't garbage either. However, if your bike isn't set up right, it will seem like garbage.

Imagine putting a satellite dish on your roof, and pointing it the wrong way. Is it the manufacturer's fault that you didn't point it at the satellite? The dish, in that case, isn't at fault, it's the person who installed it.

Bikes have to be set up. Shimano, who manufactured your shifters (and possibly your rear derailleur) didn't set up your bike. They didn't manufacture the frame onto which all of their components have been mounted, did they? So it's not Shimano's fault that whoever set up your bike didn't install their components properly. The shop that set up your bike did it wrong. Or did you set it up yourself?

Every thing from the rear was set up when it arrived. The cable was loose so i tighten it up. that's only thing i had to do for the rear of the bike.

There in lies your problem. Cable tension is a major part in how well your bike shifts.

Tiagra shifters are fine. My old touring bike had them for many many miles. I think it was flattened by a SUV around 9000 miles.

Incorrect. You can't just "tighten" up the cable. It must be correctly adjusted.

Incorrect. If it was set up, the bike would be shifting correctly. It may have appeared "put together" to you, but it wasn't set up.

Well, that was your second mistake. The first mistake was buying from someone who doesn't set the bike up for you to begin with.

If you changed the cable's tension, you changed its shifting characteristics. If you did it without knowing what you're doing, you probably are at least in part to blame for the way it's failing to shift properly now.

I think it's more likely your setup is garbage.

I've never had problems with my Tiagra shifters, either, and they are shifting a 105 rear derailleur, NOT EVEN IN THE SAME GRUPPO. How spooky is that?

Anyway, if this thread is a troll I rate it highly. If it's not, I rate it highly-er.

I think there really needs to be a "often wrong but never in doubt" category too.

I believe the OP is just trolling. He also posted a question relating to why his pump won't work with Presta valves. Some of his follow-up comments in that thread were so blatantly bizarre that it seems likely that he's either having a good laugh at our reactions, or possibly born in the year 892 b.c., and brought out of a cryogenic freeze in the 21st century. Kudos for getting the Internet figured out, if the latter is the case.

It is obvious that your knowlege of bike mechanics is limited. With that in mind I advise you take this to a qualified bike shop or check for a local bike co-op that will allow you to watch and learn while they set your bike up correctly. It is a win-win. Your bike gets set up and you gain knowledge about your machine.

The reason I can't decide on Troll-or-no-troll is because of the timeline of posts. It wouldn't be a skilled troll, but it would be a well planned out one. It's missing the the depth and humor of a good alter-ego.

One strong point in favor of a skilled troll, though, is the complete non-reaction to anyone posting negatives. You'd expect a defensive post or two somewhere.

Troll-or-no-troll analysis on internet forums? That could be decent PhD topic. Somebody probably will take my idea and run with it.

If the OP is serious. Yes. Stupidity knows no bound.

I'm not so sure that's a good indicator. pcad got on me recently, reminding me that 1000 miles in two and a half months is relatively little mileage at all (I was complaining about having to skip a few days of riding because of a knee problem). I never posted some defensive quip, because I actually appreciated the humor, and he was right. It was a fair dig, and made me laugh.

Actually, I am not sure based on a quick look at his previous posts... I would guess Iron Horse.

I hear ya bro! I do have a solution for you though. My Sora shifters work fine. I am willing to trade you for the Tiagra and just deal with only having 4 gears. I would also be willing to send back some suitable down tube shifters that are very dependable. Your choice!

Let me know.

OK, so we have Sora sucks threads and Tiagra sucks threads.

105, you're on deck!

Seriously now...
4ero, before you get all pissed off at your bike for not working right and at us for trying to help, you need to learn the basics about bikes including parts and maintenance. Derailleurs are the parts that move the chain along the casette (rear gears) and the chainrings (front gears). The one on the back sort of hangs off from end of the chainstay (part of the rearmost triangle) and directs the chain up and down the rear cogs. The front one hangs off the seat tube and moves it along the front gears.
