What’s a Shimano 105 derailleur?
On the subject of biking elements, the Shimano 105 groupset holds a particular place for fans and aggressive cyclists alike. At its coronary heart, the Shimano 105 derailleur is a basic element that manages chain motion throughout the bike’s gear sprockets. It is a part of Shimano’s mid-range line, providing a formidable mix of efficiency, sturdiness, and affordability.
The 105 derailleur is available in two varieties: entrance and rear. The entrance derailleur controls the shifting between chain rings whereas the rear strikes the chain up and down the cassette. This exact mechanism ensures which you can transition easily between gears whether or not you are climbing hills or sprinting on flats.
Shimano has designed this collection with each novice riders and seasoned cyclists in thoughts. It options a lot of the identical expertise discovered of their higher-end Ultegra and Dura-Ace fashions however at a extra accessible worth level. The newest iteration, often known as R7000, boasts improved shifting effectivity and lighter operation due to its redesigned derailing motion.
- Efficiency: Delivers dependable shifting that rivals top-tier programs.

Getting your Shimano 105 derailleur adjusted appropriately is essential for clean gear adjustments and sustaining an environment friendly journey. The method could appear daunting at first, however with a scientific method, you will have it dialed very quickly. Here is what you should know.
Firstly, familiarize your self with the 2 kinds of screws in your derailleur: the restrict screws and the indexing adjustment. The restrict screws are marked as ‘H’ for top restrict and ‘L’ for low restrict; they management how far the derailleur can transfer in direction of or away out of your bike’s body, thus setting the chain’s highest and lowest gear positions. Misadjustment right here may result in dropped chains or lack of ability to shift into sure gears.
Indexing adjustment is all about fine-tuning how a lot the derailleur strikes between every gear change. That is normally finished with a barrel adjuster situated both on the derailleur itself or someplace alongside the cable housing. A standard signal that your indexing wants consideration is that if shifting feels sluggish or when you hear a clicking noise whereas pedaling in sure gears—it is like your bike whispering for assist.

You also needs to have a Phillips-head screwdriver prepared—this instrument will enable you alter the restrict screws in your derailleur. Restrict screws management how far the derailleur can transfer and thus stop the chain from dropping off the gears or getting caught between gear sprockets.
A cable puller or needle-nose pliers may turn out to be useful as nicely if you should maintain rigidity on the cable whereas securing it in place. Pressure changes are mandatory when fine-tuning how the shifter responds.
For exact alignment, nothing beats old school ruler or measuring tape. It is helpful for guaranteeing that your derailleur hanger is correctly aligned along with your cogset; even small misalignments can result in skipping gears or poor shifting efficiency.
Lastly, remember about lubricant! A top quality bike-specific lube is vital not only for after-adjustment care but in addition for guaranteeing elements transfer easily as you make these crucial tweaks.
- Hex Wrenches (Allen Keys), usually 4mm and 5mm

Step-by-step information to adjusting a Shimano 105 derailleur
Adjusting your Shimano 105 derailleur is not as daunting because it may appear. With the appropriate instruments and a little bit of persistence, you will have your gears shifting easily very quickly. Here is how I sort out the duty, step-by-step:
First issues first, ensure you have a Phillips screwdriver and presumably a set of Allen keys at hand. These can be your major instruments for the job.
- Start with setting the restrict screws, that are marked as ‘H’ for top and ‘L’ for low. The ‘H’ screw adjusts how far the derailleur can transfer in direction of the smaller cogs, whereas the ‘L’ screw controls motion in direction of the bigger cogs.
- Shift into the smallest cog in your cassette and switch the ‘H’ screw till there’s about 1mm between the derailleur pulley and cog. If it’s too shut or too far-off, shifting gained’t be exact.
- Subsequent shift to your largest cog and alter the ‘L’ screw following related ideas guaranteeing that very same tiny hole is maintained.
As soon as these restrict screws are dialed in it is time to alter cable rigidity:
- Discover barrel adjuster on both shifter or rear derailleur itself; this fine-tunes cable rigidity.
- Shift up one gear from smallest cog then again down if chain hesitates improve rigidity by turning barrel adjuster counterclockwise if it overshoots lower rigidity with clockwise turns.
Fantastic changes right here can actually make or break shifter efficiency so take your time:
- Pedal gently whereas making small quarter-turn changes till shifts between cogs are snappy but clean.
Lastly guarantee B-tension is right:
- That is adjusted through a 3rd screw normally discovered at again of derailleur close to the place hanger attaches.
- Correctly set B-tension retains higher pulley wheel an optimum distance from cogs throughout vary of cassette which aids in stopping noisy drivetrain or poor shifting beneath load.
Bear in mind every bike setup may require barely totally different tweaks resulting from distinctive put on patterns or element variations. Maintain testing shifts after every adjustment till the whole lot runs like clockwork!
Frequent points and troubleshooting ideas
Adjusting a Shimano 105 derailleur can typically be difficult, however it’s key to a clean journey. I’ve discovered that almost all points fall into a couple of classes:
- Incorrect indexing
- Cable rigidity issues
- Restrict screw misadjustments
- Bent derailleur hanger or derailleur cage
On the subject of incorrect indexing, you will discover the gears aren’t shifting cleanly. The chain may soar a number of cogs or fail to shift in any respect. Here is what I usually do:
- Shift into the smallest cog.
- Launch the cable rigidity by turning the barrel adjuster clockwise.
- Pedal ahead and gently flip the barrel adjuster counterclockwise till the chain runs easily on every cog.
Cable rigidity is usually underestimated but it’s important for exact gear adjustments. In case your shifts are sluggish, growing cable rigidity might help:
- Find the barrel adjuster at both finish of your cable run.
- Flip it counterclockwise in small increments whereas pedaling.
- Proceed this adjustment till shifts are snappy and immediate.
Now let’s discuss restrict screws, which management how far the derailleur strikes outward or inward. Misadjusted screws may result in dropped chains or refusal to shift into sure gears.
- The ‘L’ screw controls inside motion (towards bigger cogs).
- The ‘H’ screw controls outer motion (towards smaller cogs).
A bent derailleur hanger is one other frequent wrongdoer for poor shifting efficiency; even slight bends can throw the whole lot off steadiness.
- Use a hanger alignment instrument to examine its straightness.
- Rigorously bend it again into place if wanted – although typically substitute is important.
Bear in mind, persistence is essential when adjusting your Shimano 105 derailleur, and minor tweaks could make an enormous distinction!
