I have an old shimano Crane gs rear derailer that needs to be adjusted higher off the gears. I have found the side to side adjustment screws but there isn't another screw on it like on modern derailers

SOURCE: adjusting front derailer

Typically adjusting the front derailleur is a matter of adjusting the two adjusting screws on the derailleur. So turn the bike upside down. It should sit on its seat and handle bars. Find the two adjusting screws one will prevent the derailleur from traveling too far out preventing the chain from coming off. The other screw prevents the derailleur from traveling too far in keeping the chain from falling off that way. Now once you have found the screws slowly start turning the pedals like it was being ridden. Move the derailleur out as far as it will go if you see the chain is about to come off adjust the screw. Do same for inside screw. Now move the back derailleur all the way in and retest front derailleur, repeater with rear derailleur all the was out. Hope that helps. Oh, the back derailleur adjusts same way.

SOURCE: broken shimano 105 flight deck shifter

You may have broken your derailleur cable. Your cable securing bolt on your front derailleur might have worked loose just enough for the cable to get some slack in it so that your derailleur isn't moving. Try completely loosening the cable bolt at your front derailleur. Pull on the cable and click the control to downshift to the inside crank gear . That should remove all the slack from the cable. Worse case scenario is when you pull on the cable it will completely pull out and it has broken at the shifter. You will have to replace it with a new one. If it isn't broken and you can still shift with the cable make sure your limit screw is properly adjusted for the inside crank ring and then pull all the slack out of the cable with the shifter shifted to that gear. Tighten the bolt that holds the cable in place and try the shifter again. It should now shift normally. If it doesn't you will have to take the bike in to have the shifter repaired. These shifters are not easy to repair unless you have the tools, parts and experience. Hope this helps.

SOURCE: Deore front derailer cable stay hex nut access

Try unhooking the chain from the ring and pulling the derailleur out far eough to get at the bolt. Make sure your limit screws are adjusted for the travel yuou want and take up the slack. You can use the cable adjuster on the shifter to tighten it or loosen it as necessary. Make sure the adjuster has enough to go in the direction you need. I don't know which model Diore you are talking about so this is the best advice I can give you.

SOURCE: Changing shifters on my Trek 1400

Of course it can be converted to anything you want - at a price and with some effort. I recently converted a vintage 1984 Cannondale road bike from 2x7 Suntour downtube to full Campi 2x9, carbon crank, yada yada. I like riding it as much as any of the other 3 road bikes I have.

I sourced most of the parts for my various bike projects on eBay. If you're looking for vintage or retro, that's where you go. Just avoid buying cassettes that have been 'slightly' used.

Assuming your bike is still an original 7- or 8-speed, and you want to keep it that way, you may have to hunt around for compatible shifters. Upgrading from 7- or 8-speed to 9 may be the way to go, but then you'd have to get a new cassette (minimum) or a new wheel, or it may not fit into your frame's rear dropouts as the axle spacing crept up over the years with the addition of cogs.

Consider all the individual steps conversion may require; and if each requires yet another modification or encounters a dead end, like frame spacing. At retail prices for parts these days it might be more economical to get a new bike. OTOH, there's no matching the satisfaction of keeping a favorite steed active and doing the work yourself.

The problem is with the rear derailleur limiting screw. This is what limits the travel of your chain and keeps it from overshifting into the wheel. This fix is a bit complex so I would recommend you take into your local bike shop. They can probably fix it on the spot and if you have a good relationship with them they won't charge you too much.

I have replaced the cable on the 7speed Shimano SIS derailler and Ithink I ran the cacle through the shifter wrong. I can only get three gears to shift. This is a combo brake and shifter handlebar mount.


Hi,

All shimano derailleurs have two small screws located on the mechanism itself that allow you to adjust the position of the derailleur relative to the gears. The top one adhusts how far towards the wheel the chain can go and the bottom of the two adjusts how far towards the stop it goes.

Put the bike on a stand or just prop it up so the rear wheel can spin freely when you turn the pedals by hand

Put the shifter in the highest gear and turn the pedals, the adjust the top screw until it enters the top gear, you may need to adjust the cable tension also to do this.

Once you have it going easily into and out of the top gear adjust the bottom screw so that it easily goes into the bottom gear.

You should be done! Don't forget that for the first few rides the cable will stretch out a little so you may need to tinker with those screws a couple more times.

Hope this helps:)

Shimano Derailer 200GS needs adjusting How do I do that?


There is a barrel adjuster on the derailer, right where the cable comes in.

If you are having trouble getting to the easier gears then you need to tighten (usual problem -cable stretches). Pull out the barrel adjuster and unscrew it (turn CCW). Do this gradually until you get the shifting you want.

There are also two little adjusting screws on the face of the derailer that limit the travel of the derailer(keep it from jumping off the cogs, into the spokes or outside it). It is good to check these while you are working on it. The upper one is usually for the easiest gears, screw it in until you can no longer shift to the easiest, then unscrew it just a bit so that you can get in gear, but so the erailer can never go too far). If nothing happened, it is the other screw, so tighten that one.

Now do the other screw, tighten it until you can no longer shift to the smallest cog , then unscrew a bit, making sure you can shift to the smallest cog.

Hope that helps

Adjusting the tracking for a shimano 515 revoshiftrear rear gearchange difficult to see what the 2 small adjustiing screws do I only get 5 of my 6 speeds


The screws adjust how far the derailer can move. If you can't get to the gear on the outside then loocen the screw in the outside. If you can't get the biggest gear loosen the other screw. For most derailers, loosening it will do what you want but watch the derailer move. If it moves the wrong way, turn the screw the other way. If you still need some help, I suggest you contact your local bike shop for help.

Take a look at the diagram in this link, see the two screws identified as Number 3. http://techdocs.shimano.com/media/techdocs/content/cycle/EV/bikecomponents/RD/EV-RD-TX31-2753B_v1_m56577569830637983.pdf
You need to adjust both screws, since one adjusts how far in the derailer goes, and the other adjusts how far out it goes. Start with the bike in a mid-gear and turn one of them 1/4 turn. Check the result. Proceed by trial and error. Good luck. If you found this helpful, please vote. Al K

There are two screws that limit how far the derailer travels in both directions. Yours is apparently traveling to far out, and not far enough in. See the diagram at the link below. The two screws are identified by number 3. You will need to adjust both of them. With the chain on an intermediate gear, try turning one of them them 1/4 turn, then check the result. You'll soon get it right. Good luck. If you found this useful, please vote
