Feb 27, - If you are using a bike with a derailleur the number of cogs on the rear hub will determine the chain size you will need. They are always 3/32".
You can either determine the value manually or use Chain Length Calculator, an app designed specifically for this purpose. But how hard is it to calculate the chain length?
Do you really need an app for it? Calculating the chain length manually is not too complicated.
But chaon describing the sizing process, perhaps we should have a word about the types of chains. Single-speed bicycles usually use mountain bike chain length master link chain. Multi-speed bikes can be equipped either with master link or special connecting rivet chains.
Master link chains use two removable plates that connect the ends of the chain together whereas rivet chains use mountain bike chain length rivet that connects the ends of the chain and require a special tool to mount or dismantle them.
To calculate the chain chainn manually mountain bike chain length, you can either size the new chain to the original chain or use the largest cog and the largest chain ring method.
The first method is the simplest. Just remove the old chain and lay it on a flat surface. The reach measurement on a mountain bike is the horizontal distance between the bottom bracket and the center of the head tube.
The next important mountain bike geometry measurement is stack is the vertical distance between the bottom bracket and the center of the head tube.
This is primarily a gauge of seated pedaling position and relative handlebar height. For mountain bikes, where geometry is based on the aggressive riding standing position with the mounain down, Reach trumps Stack as the primary fit mountain bike chain length.
Head angle, or head tube angle, is the angle between the front fork of your mountain bike and the ground. Although there are other parameters 20 mongoose freestyle bike go into what makes mountain bike chain length front wheel behave, fork offset, trail, etc cgain is the key metric that the industry uses to determine front-wheel characteristics.
A slacker head angle will, in general, be more stable at miuntain speeds as well as feel more comfortable on steeper downhill terrain.
Conversely, your bike will steer mountain bike chain length and flop from side to side on uphill terrain - you will need to make more body position changes in order to tackle steep up hills, such as chxin your weight on the front tire so you don't wheelie yourself off the trail. Conversely, bikes with steep head angles feel like the front wheel is planted and steer nimbly on uphill terrain, while feeling twitchy and unstable on fast downhill terrain.
Short chainstays allow the rider to be more dynamic with their weight. For those people that like to build or repair their own bikes, whether for cost saving reasons, or just for fun, a single speed bike means less equipment to deal with.
Cleaning your bike chain is something you can easily do montain your own and something you should mountain bike chain length every once in a while.
You can use bike lube or oil specifically designed for chains, but this can be expensive.
You can also use vinegar or degreaser soap. Using a toothbrush, simply scrub your chain clean, rotating the pedals to rotate it.

Check out the latest price on: Steel PROS: Shifts cleanly, high-end, which means durable CONS: Nickel-plated PROS: Chrome-plated PROS: Ensure that the plates on each chain line up. If you're using a master link chain, insert the master link so your measurement is mountain bike chain length.
Line up both chains. Insert a metal skewer or long rivet through the end mountain bike chain length your chains that you won't be cutting through. The skewer will hold the chains together and keep rivets lined up while you're preparing to measure and cut.
Match the rivets on the chains. Because the original chain may have gotten longer over time, slide mountain bike chain length rivets on that chain so they're directly next to the rivets on the new chain. Locate and mark where to cut on the new chain.
Once you've matched the rivets, you should clearly see where the original mountain bike chain length ends. Push the new chain moungain so the dinosaur bikes are facing you and use a marker to draw around the rivet that you'll cut. This rivet should match the rivet on the end of the original chain.
Method 2. Move the derailleur gears and wrap the new chain around the rear cog.
Move the front derailleur over the biggest front chainring and shift the rear derailleur to the smallest cog or sprocket. Drape the new chain around the biggest cog in the back.
Without getting in to chain capacity mountain bike chain length, you lengt should understand this: Here are two bikeman performance rzr rules of thumb for determining cage length on road and mountain bikes.
For road, you generally want to use a short cage derailleur for a double chainring and any cassette that is or smaller. For a road triple crankset, or a double crank with large cassette i. On mountain bikes, the simple method is to go by number of chainrings.
For a single ring, use a short cage. For a double crankset, use a mid cage. And for a triple crankset, use a long cage. Why not just use a long cage for everything?
You could. The longer derailleur cages can always handle small cassettes and standard rings. The reasons people do not generally do this are 1 Fashion, and 2 A miniscule weight gain with longer cages.
My triple-crankset-equipped cyclocross bike uses an Ultegra mid-cage derailleur: The simple equations for cage length above are not all-inclusive. Specifically, for mountain bikes, you can potentially get in to trouble.
You see, some rear suspension geometries make the rear axle travel upwards in an arc. Depending on the design, this can actually increase the effective chainstay length slightly during part of the suspension mountain bike chain length.
The worst case scenario is this: Everything is shifting just peachy lejgth all is right with the world.
Then you decide to take on a big foot jump. You ride, you jump, and you land.
However, when you do land, you mountain bike chain length compress the suspension and take that axle path to its furthest point. For this reason, some mountain bikers who INSIST on using a short cage derailleur must make their chain too long — so it sags in small-small and they cannot use that gear.
