What does derailleur capacity mean?
Rear derailleur Total capacity
It is the maximum amount of chain slack a derailleur can take up or let out, expressed in a number of sprocket teeth. Exceed the total capacity, and your chain will likely be too long or too short for some combinations of gears.
How do you calculate derailleur capacity?
Subtract the number of teeth on the smallest chainring from the number of teeth on the largest chainring. 52-36= 16. Now subtract the number of teeth on the smallest cassette cog from the number of teeth on the biggest cassette cog.
What is front derailleur capacity?
A front derailleur’s capacity is simply the difference between the number of teeth on your largest and smallest chain ring. For example if you have a 39/53 chain ring combo, (53 – 39 = 14), you will need a front derailleur with a capacity of 14 teeth or more.
What is chain capacity?
Chain-wrap capacity is a number that tells whether or not a derailleur will be able to do this on the drivetrain you plan to use it on.
How do I know if my derailleur is short or medium?
How To Find Out If Your Bikes Rear Derailleur Is A Short Cage Or Long …
Which is better long cage or short cage derailleur?
It’s generally best to go for as short a derailleur cage as you can get away with, as long as you can avoid the chain contorting on the extremes of the cassette, such as using the largest on both sprocket and chainring. Smaller cages tend to have snappier gear changes, they’re lighter, and also less exposed to damage.

Do I Need A Short, Medium Or Long Cage Rear Derailleur? – YouTube
What does GS mean on Shimano derailleur?
medium cage
Shimano rear derailleurs are available in two types, SS (short cage) and GS (medium cage), depending on the model. The “cage” here refers to the length of the pulley cage (the unit that houses the two pulleys).
How do I tell what Shimano derailleur I have?
Simply look on the back of the derailleur body. The model number should be stamped there. It should read RD Mxxx. I’ve never seen a Shimano derailleur that didn’t have the model stamped there.
How do I know if I need a long cage derailleur?
How do I know if I need a medium or long cage derailleur?
Derailleur cage length quick guide
In these circumstances, you will require a long cage derailleur. If you are running a 1x drivetrain with a regular-sized cassette (i.e. 11-36t or smaller) or some 2x mountain bike drivetrains with a similarly sized cassette, you may want to use a medium cage derailleur.
Which is better SS or GS?
The difference between SS and GS is technically as follows. To make it easy to remember, SS (short cage) is compatible with cross ratio road sprockets, while GS (medium cage) is compatible with wide ratio sprockets. Cross ratios, wide ratios, the world of gear ratios is a deep one.
How do I know if my derailleur is GS or SS?
Is all Shimano 10 speed compatible?
All Shimano and SRAM cassettes up to 10 speed are broadly compatible. They all use Shimano’s Hyperglide II freehub body spline pattern. Cassettes with the same number of sprockets have the same sprocket spacing, sprocket width and overall width.
What the difference between a short and long cage derailleur?
A chain that slacks can be represented as the force acting on the lever (derailleur’s cage in our case) and puts tension on the spring. Long cage = easier to move / short cage = harder to move. If you use only one chainring you can use a short cage derailleur.
What’s the difference between medium and long cage derailleur?
If you are in-between the capacity ranges of the two, which is often the case with mountain bikes, then note the following: long cage derailleurs will accommodate a wider gear range and deliver a better chain line, while medium cage derailleurs are less likely to be hit by rocks on the trail.
Do I need short or long cage derailleur?
What is GS derailleur?
“-GS” refers to medium-cage rear derailleurs, built with a maximum chain capacity of 37T to 39T or less. This is usually the longest cage offered for road bike rear derailleurs, but also the default “short” option offered for their mountain bike counterparts.
Which is better Tiagra 10 or 11 speed?

Shimano have announced that their Tiagra groupset is to go 10 speed for 2012.
What are the advantages of a short cage derailleur?
logged out. Short cage derailleurs generally have higher spring tension, having a shorter cage means less chainslap too. A closer range cassette, such as a road cassette, means less jump between the gears, so you can accelerate through the gear range smoother than you can with big jumps through the gears.
How do I know if I have a short or long cage derailleur?
What is meaning GS and SS?
GS – Graduate standing. JS – Junior standing. SS – Senior standing. SYS – Second/Sophomore year standing.
Is Shimano Tiagra good enough?
Tiagra is good enough for 99% of riders, make no mistake. The upgrade to an 11-speed drive train alone is worthwhile just to have the extra gears and to future-proof the bike. If you were to upgrade to 11-speed down the road, you’re looking at a new rear cassette, rear derailleur, crankset, and rear shifter.
What level is Shimano Tiagra?
Shimano’s Tiagra is an entry level, 10-speed groupset often spec’d on many sub-£1000 value and city bikes for its durable and reliable properties.
