What is the difference between long and short cage derailleurs?
In addition, the difference between the long, medium, and short derailleurs is the length of the cage. The cage is those 2 idler wheels on the rear derailleur. In a short derailleur, the idler wheels are closer to together while a long derailleur they are further apart.
How do I know what size derailleur cage to get?
Most manufacturers offer rear derailleurs in three cage lengths: short, medium, and long. The most simple and straightforward way to think about cage length is as follows: the larger the range of gears you have, the larger the cage you’ll need. Range is the difference between your biggest and smallest cog.
Does derailleur cage affect chain length?
In short, the wrong length derailleur cage will make determining proper chain length nearly impossible. Too much chain length and you’ll have shifting issues and suffer from dropped chains, but too little could rip your bike’s derailleur right off.
Can I change derailleur cage length?
Its not just the tooth capacity, the maximum sprocket size the derailleur is rated for can also change with the cage size in the same product line (i.e. they’re not just changing the cage), with the maximum sprocket size going up with cage length.
Do I need a longer chain for a long cage derailleur?
The general rule of thumb is that the larger the gearing range, the longer the derailleur cage needs to be.
Can you make a short cage derailleur into a long cage?
Yes, if the derailleurs are the same model, and you can get all the parts, (which isn’t usually a straightforward process) youcan convert from short cage to long cage.
How big is a 10 speed Rd cage?
Long cage 10 speed RDs have a MAXIMUM tooth capacity of 47t (XX long cage rear derailleurs have a maximum tooth capacity of 40t), medium cage has a max capacity of 37t, and short 30t. MTB LONG CAGE: 93MM pulley bolt to bolt MTB MEDIUM CAGE: 75MM pulley bolt to bolt CAGE CAPACITY 10 SPEED:
Which is better 11-32 or 11-34 cassettes?
The next generation 105 R7000 and Ultegra R8000 medium cage derailleurs officially support up to 11-34, for 6% lower gearing than 11-32. Shimano offers two 11-34 road cassettes (105 CS-HG700, Ultegra CS-HG800) that are functionally the same, but the Ultegra cassette is about 10% lighter.
How to determine cage size for rear derailleur?
Cage sizing for the rear derailleur will depend on tooth capacity– meaning the difference in teeth in the drive train. The equation to find this number is (teeth difference from largest to smallest cog on the cassette + teeth difference from largest to smallest chain rings on the crank)= total tooth capacity of the drivetrain.
