There is more that needs to be added to that question. What are you having the hard time with? There are several things that hold your wheel in the front as well as several styles of axles. Please tell us more and we will help as we can.

Or, just e-mail me and we'll hash it out:

Shift to your top gear before removing the wheel and as you take the wheel out, pull back your derailleur to make it clear the cassette more easily.

Front or rear? Is the cable not in the shifter?
If the cable is not in the shifter, there will be a screw in the shifter (made of plastic, usually black) facing outward. You open this and shift the shifter into the highest gear, then slip the cable through and out the side that accepts the cable sleeve. Then you run it through the sleeve and to its appropriate derailleur (left hand=front, right hand=rear).

You may have too large a tire on the back for the bike. However, if the derailleur hanger is bent, this could also cause the problem. Flip your bike over onto the bars and seat and make sure the derailleur alignment is good (vertically and longitudinally straight). If the derailleur hanger is straight, then you will have to use a narrower tire in the back.

Yes and no. For the most part, since you've got a pretty standard 14inch tire, it should fit on most stander 14inch rims.

If you've got a set of sports rims (which are most likely wider than stock) then it may not fit

i tell you the problem is not much, therefore don't panic yet. but one thing, secure your sim card very well and and visit a nearby sim card provider (i.e your network) and explain to them every thing. jxt have patient and everything will still be alright with your number. Meanwhile, also pray to get it back because it is a valuable property.

just go straight 2 your sim card provider, ok? then if u are using an iphone, you can go to the net and visit thier website, there they will give u a solution.

It could be a d-rail, but also could be spokes, chain rub, wheel hitting a brake pad, tire clearance at frame, bearings.
Put your bike upside down so you can turn the pedals while you check for where this may be coming from.
Take your time... these noises can "telegraph' thru the frame and fool you so look for visible signs, use a little chain lube, oil , etc and you'll be able to pin point your noise.
I had an issue on my high end road bike.. a clicking while pedaling uphill...very annoying... turned out to be the added pressure caused the rear wheel spokes to click at the crossover point... a little heat shrink tubing did a nice alteration without a spoke pressure increase... So look around , start eliminating the possiblitites and you'll find it!

There are good instructions here under front and rear derailleur adjustments:http://www.parktool.com/repair/byregion.asp?catid=53 This is my favourite site:http://sheldonbrown.com/gearing/index.html Hope this helps.

depending on how much you use the bike. you may have to replace or re-aline the gear cable that runs through the bike.

The old lubricant has gummed up. It needs a good cleaning and relubrication.
"STI shifters gum up after years of use. I've had good luck with this method and since it's nearly free it's probably worth a shot--

"Get a can of WD-40 or a similar light solvent/oil solution. Pull the brake lever back to the bar to partially expose the shifting mechanism and generously hose down the interior with your solvent. I mean really get it in there from all directions, using the little red spray tube if possible. Let it sit for a while and then drizzle in some light oil like Tri-Flo or similar. Then wipe down the exterior of the shifter with some Simple Green or other degreaser (to keep the overspray off your hands).

"I've rescued two sets of STI-type shifters with this method. Hope you get your problem solved one way or another, because new Dura-Ace sure ain't cheap."

My guess is the shift cable has slipped, only allowing you the top end of the rachet positions. Drop the shifter to the very lowest cog, make sure the cable is tight, and adjust the tension at the derailleur so that on the first single click it climbs one gear, and isn't noisy there. More tension 9 winding the barel out ) causes it to rise, less, to drop down. It should then hopefully select all the gears, unless the upper stop, the L screw is set too low. This screw stops the derailleur hitting the spokes and going past 1st gear. That shouldn't ever change though.

Try disconnecting the cable as you would if you were replacing it. Check the cable for wear (frayed wires in the cable). While you have the cable out try shifting it to see if it now works. Check http://www.bikeforums.net/archive/index.php/t-194308.html for an article which may help.

find where the cable makes contact near the wheel, with the lever of the brake. squeeze the 2 levers toghether(rubber-bands are useful) then loosen the bolt holding the cable. take out some of the slack and re-tighten. remove rubber band. repeat as necessary to achieve desired tension. hope this helps!!?

Go to Parktool.com it's real easy. good luck

Forget the screws as those are more for fine tuning once you are close to having it set correctly. Where the shift cable connects to the shifter on the bars you will typically find an adjustment knob (note that you may have the same type of adjustment knob where the cable meets the gear shift mechanism also) which the cable rides in. You will make much larger jumps in adjustment when using this method as opposed to using the screws located on the gear changing mechanism. Best of luck to you on the fix!!

well usually all chains have a link that comes off. if you get that to come apart, then you put the chain on the teeth were the teeth come through between the links. then you link back together the two chain links. it might be a little hard though

You may have a bent or warped disc. This happens much more easily than one would expect. You will have to remove the disc from the hub and lay it on a perfectly flat surface to see. If it is you can try remounting it and make sure the torx screws are snug. Tighten them the way you would when changing a car tire in an X pattern. Then try gently but firmly bending the disc in the opposite direction in the spot where it is rubbing. Some people have used thin washers behind the disc in the closest mounting hole but I would recommend a new disc.
