How do you adjust a Shimano XT front derailleur?

How do you adjust a Shimano XT front derailleur?

To adjust the height of the front derailleur, locate the positioning clamp that connects the derailleur to the frame of the bike. Turn the clamp bolt clockwise to loosen it and then adjust the height. Tighten the bolt once it’s adjusted.

What angle should a front derailleur be?

So those (“Shimano”) angles are often 61 to 66° degrees for road FDs, and 66 to 69° for MTB front derailleurs.

How do you find the stay angle of a chain?

Re: Chainstay angle – measuring The angle you want is the included chainstay angle, i.e. the angle between the chainstay and the seat tube. The easiest way is probably to take a photo (or dwg) of your frame and to measure it directly using a protractor.

Should the chain touch the front derailleur?

The front derailleur cage should be approximately parallel to the chain. If the derailleur cage is rotated too far from this position, it will shift poorly. If the derailleur mount is a clamp type, its rotation can be changed. Generally, the outer cage of the front derailleur should be aligned to the chain.

Why is my derailleur hitting my cassette?

Most derailleurs will drag on the top cog of a 34 t cassette when the bike is upside down, but not when it’s right-side up. If it does it when it’s right side up, shorten the loop of cable on the derailleur. Shortening the housing loop is not the best idea. You should adjust the b-tension screw.

What does chainstay angle mean?

Chain stay angle is the angle between a line drawn from the bottom bracket axle center and the rear wheel axle center, and the seat tube (or a line from the BB axle center to wherever the front derailleur is mounted if there is no traditional seat tube).

What is a chain stay angle on a bike?

Chain stay angle generally refers to the angle from the rear axle to the center of the bottom bracket. In BikeCAD, this dimension is identified as Chain stay angle (Rear axle to BB).

What is chain slap?

Chain slap has a few cheap and easy solutions. When it comes to noise, one you cannot miss is chain slap, down every rough downhill section or off every drop your chain makes a right racket slapping up and down against your swingarm.

How tight should the front derailleur cable be?

You need to pull it pretty tight before clamping it to the derailleur. Probably as tight as you can. Usually I find that’s still not tight enough, so I screw the barrel adjuster down all the way before putting the cable in and then open it up until the tension is correct.

What should I adjust first front or rear derailleur?

In a nutshell, adjust the front derailleur first, then the rear. Show activity on this post. If the derailers just need minor tweaking (they are basically in adjustment but are “not quite right”) then you adjust the one that is obviously wrong, check the overall adjustment again, then again adjust what needs adjusting.
