How do you calculate gear 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 the max cassette for short cage derailleur?
The total capacity of a SS (short cage) Shimano derailleur is 35t and 39t for a GS (medium cage) derailleur.
What does derailleur total 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.
What is Max Front difference?
Maximum front tooth difference is an invented spec that Shimano has begun using to attempt to present compatibility data to consumers in a way they think will be simpler or more effective or whatever. Maximum front tooth difference contains zero information not already present in the total capacity number.
Do I need a new derailleur if I get a bigger cassette?
You’ll have bigger jumps between the gears, but you’ll have a bigger range of gears. With a wider range cassette, you may need a new rear derailleur with a longer cage.
Can I change cassette size?
Quote from video: Change you can make is to swap your cassette. If you count the number of teeth on the biggest sprocket at the cassette or if you look carefully. It's normally written on there it'll.
Is an 11 34 cassette good for climbing?
All other things being equal, the 34T sprocket on the 11-34T cassette is going to give you the easiest gear. If your bike is currently fitted with an 11-28T cassette, switching to an 11-34T cassette will make climbing less of a struggle.
Can I use 12 speed derailleur with 11 speed cassette?
So there you go folks, there is no difference in indexing spacing between 11 and 12 speed, the difference is all at the derailleur end. So you can’t use a 12 speed derailleur on an 11 speed setup or vice versa but you can you an xtr 12/11 speed shifter on an 11 speed drivetrain.
Can I use 11 speed derailleur with 10-speed cassette?
Can An 11-speed Derailleur Work With a 10-speed Cassette and Shifter? Condensed Answer: Shimano’s 11-speed derailleurs have a different rear shift ratio than 10-speed derailleurs and are therefore not compatible with 10-speed indexed shifters.
What happens if you exceed derailleur capacity?
So if you exceed the specs, it won’t be dangerous for the derailleur, but the shifting won’t be optimal, or it will rub, or may not work at all, because the cage will be too big/small or the grooves won’t be at the right position, or the parallelogram won’t be aligned properly.
How many teeth can acera handle?
Chain-wrap capacity: 45 teeth.
What is Max chainring size?
Standard double cranks – the most common combination is 39 tooth inner and 53 tooth outer. Older chainrings will be 42T inner and 52T outer. The smallest inner chainring possible is to 38T. The largest outer chainring possible is 55T (without changing to a different front mech).
Can I put a different size cassette on my bike?
Yes, you can. If a smaller cassette suits your needs and terrain more, there’s no reason why you can’t put it on your bike. It doesn’t affect the function of your bike or drivetrain in any way and shifting will not be different.
Are cassette cogs interchangeable?
In some cases, it is possible to run a cassette from a different brand than the rest of your drivetrain. SRAM and Shimano cassettes, on either road or mountain bike, are interchangeable with each other as the spacing is the same between the sprockets.

What is gear module formula?
The relationship is shown as the following formula. m = p / π Figure 2 – Two gears of module 2. They mesh together correctly because their modules are equal. By the way, the pitch circle diameter of a spur gear (d) can be obtained by multiplying the module (m) and the number of teeth (z).
How is internal gear calculated?
The correction, xc, is the magnitude of shift which was assumed to be: xc = 0.0075 zc + 0.05. There will be an involute interference between the internal gear and the pinion cutter if the number of teeth of the pinion cutter ranges from 15 to 19 (zc = 15 to 19).
How do you calculate gear addendum?
addendum ha=(1+x)*m. dedendum hf=(1.25-x)*m.
7. Profile shift coefficient (x)
- With profile shifted, we can avoid teeth undercutting with fewer teeth number. …
- Fine tune of center distance. …
- Make the pinion stronger.
What gear ratio means?
The gear ratio is the ratio of the number of teeth in the gear to the number of teeth in the pinion, the pinion being the smaller of the two gears in mesh.
What gear ratio is best for speed?
In the real world, typical street machines with aspirations for good dragstrip performance generally run quickest with 4.10:1 gears. Lower gears are required if the car is very heavy, or if the engine makes its power at the upper end of the rpm scale.

Which gear ratio is faster?
A lower (taller) gear ratio provides a higher top speed, and a higher (shorter) gear ratio provides faster acceleration. . Besides the gears in the transmission, there is also a gear in the rear differential. This is known as the final drive, differential gear, Crown Wheel Pinion (CWP) or ring and pinion.
