bike problems...

I took my bike to get tuned at a sporting goods store (scheels), and have some complaints. I know I should have went to a real bike shop, but the ONE shop is no longer in business.


My biggest concern was the shifting, I tried to adjust it myself but failed (front der. mostly was the problem). I figured I needed a new cable, so I just let them deal with it. Anyways with the new cable, the chain still rubs the der. guide in either the mid, or high gear, (either inside or outside, depending on how tight the cable is set up on the shifter adjustment.)

Next wheels. They were probably bad when I took the bike there, but they didnt make them much better. When I spin the front wheel its not hard to tell its not perfectly true. And when pedeling the rear wheel at high speeds (bike sitting on the seat/handlebars), will cause the bike to shake.


I paid 70 dollars for this **** (they decided it needed to be cleaned too), and am pertty dissapointed. Im wondering what you guys think about this situation, and how I can fix the front der.




Bike is a GT avalanche 2.0 btw, about 3 seasons old.

I've got a buddy that has one of those, pretty snazy bike for the price I suppose. Yeah, take it back or learn to do it yourself. Derailleurs arn't that hard to adjust, like everything it just needs some practice and guiding.

i had the derailleur problem with my hardrock comp... but then it got stolen so i didn't have to worry about that...
i would buy zinn & the art of mountainbike maintanence (or however its spelled) its a really great book and i've learned alot from reading it.
good luck

Or just use these fora, www.parktool.com and Shimano's exploded view docs to learn. It's not that hard, I mean I don't adjust gears and stuff very often so I forget which screw does what. It just takes a few minutes to find out! It does take a bit of fiddeling and it certainly takes a lot longer time than it does for the pros but it makes you feel good to be able to sort your own gear out.

Is the derailleur rubbing all the time or just when you are in the small front, bigger rear or big front, smaller rear gears? Or even in the middle front and biggest or smallest rear gears? If so then it is pretty normal. Most front derailleurs rub from time to time. If it rubs all the time then it is a problem.

If the bike was pretty dirty then I don't blame them a bit for charging you to clean it. I hate working on a dirty bike. It is common for shops to charge up to $25 extra if you bring a dirty bike to them to have work done.

my rear wheel makes my bike shake at high speeds too. the valve stem is what causes it. i use shrader (and i assume you do too) so it's enough weight to throw off the balance.

truing your wheels is something that takes some practice and a lot of diligence. i havent decided if its worth the extra work to save me some money.

for the front derailleur, you'll have to play with the barrel adjusts and high/low adjust. if the chain is rubbing the right side of the derailleur in the lowest gear, then mess with the low adjust until it moves the derailleur to the proper position. also, make sure your chain isnt going from the little gear in the front to the little one in the back. keep in mind that you probably wont use that combination so if thats the only time it rubs, dont worry about it.

good luck

oh yah, feel free to ***** at those dudes at the sporting goods store. maybe you can get a discount or free items from them. just a thought.
