The chain stay is the part of the bike that holds your back wheel. It runs from the back wheel all the way to the bottom bracket and seat tube. The length of the chain stay determines how close or how far your rear wheel is from you.
What is a chain stay on a BMX bike?
The chainstay or “stays” = The pair of frame tubes that joins the bottom bracket shell to the rear axle holders (the slots the back wheel goes in). This means that the chain stays connect the bottom bracket (BB) to the center of the back wheel.
What does a chain stay do?
Longer chainstays increase the wheelbase of the bike, with a number of effects. More stability: A longer chainstay and longer wheelbase helps to make the bike more stable at high speeds.
What's a chainstay on a bike?
What is chainstay length? The distance from the center of the bottom bracket to the center of the rear wheel axle. This measurement is taken from the side view of the bike, ignoring the z-axis such that the width of the axle or bottom bracket does not come into play.
How does chainstay length affect ride?
More Stability
Lengthy chainstays provide a longer wheelbase which results in greater stability when riding at high speeds. Also, a longer bicycle is less susceptible to redirections caused by road irregularities and strong winds because the rear end isn't as “jumpy”.
38 related questions foundWhy is chainstay length important?
Our most popular designs include our Inline stays and Chopped stays. The popular perception is that chainstay length is one of the most important factors in bike design because stay length affects bike handling, acceleration, climbing ability, and descending stability.
What is considered a long chainstay?
less than 16 ½ inches. Touring bikes: 42 to 43.5cm… less than 17 ½ inches, or an inch longer. Some 29ers go a little longer, but in the mainstream market (and including 99 percent of all artisanal customy bikes), it is rare to impossible to find chainstays as long as they should be.
What is chain slap?
Chain slap has a few cheap and easy solutions. When it comes to noise, one you cannot miss is chain slap, down every rough downhill section or off every drop your chain makes a right racket slapping up and down against your swingarm.
What are Chainstays?
Chainstay: a pair of tubes on a bicycle frame that runs from the bottom bracket to the rear fork ends. Chain tensioner: a device to maintain proper chain tension.
What is front derailleur?
The front derailleur is the mechanism that shifts the chain on bike with more than one front chainring. There are many different makes and models, but they all share the same basic design and functionality. Front derailleurs are attached to the bike with either a clamp or bracket. Clamp mounted derailleur.
What is a seat stay?
Seat Stays
The seat stay connects the seat tube to the rear dropout. Most bike frames use two parallel tubes that connect above the rear wheel. This is also the spot on the frame where the rear brake caliper is attached.
What is head angle on a bike?
The head angle is the angle from horizontal, to the angle that your fork sits at. Generally on a mountain bike, it will be anywhere from 62 degrees (slack) to 73 degrees (steep). Cross country bikes have steeper head angles, whilst downhill bikes have slacker head angles.
What is a bike dropout?
A fork end, fork-end, or forkend is a slot in a bicycle frame or bicycle fork where the axle of a bicycle wheel is attached. A dropout is a type of fork end that allows the rear wheel to be removed without first derailing the chain.
How does a chain catcher work?
If you're not familiar with the concept, a chain catcher is a length of aluminium that attaches to your front mech bolt, extending downwards to stop your chain from overshifting inwards. Its job is to get in the way. That's all.
Is chainstay necessary?
There is a need for a Chainstay protector to protect the bike from scratch, dents, and other such things. If you want to keep your pride and joy looking pristine without any scratches and dents, then you must apply a Chainstay and frame protectors.
How do bottom brackets work?
The bottom bracket on a bicycle connects the crankset (chainset) to the bicycle and allows the crankset to rotate freely. It contains a spindle to which the crankset attaches, and the bearings that allow the spindle and crankset to rotate. The chainrings and pedals attach to the cranks.
How do you measure chain stays?
Chainstay length is measured from the rear axle to the center of the bottom bracket. Trials bikes typically have shorter chainstays than most other bikes.
What is a dropped chainstay?
Dropped Chainstay
This is a driveside only modification, so the pair of stays is asymmetric. The “dropped” stay in this pair curves downward as it approached the bottom bracket shell and back up again to join the frame.
What is a rear derailleur?
The rear derailleur is the mechanism that shifts the chain at the rear sprockets. There are many different models but they all share the same basic design and functionality. Derailleurs are secured to the bike with a mounting bolt to the frame's derailleur hanger.
What does a bicycle clutch do?
The purpose of a bicycle clutch is to retain chain tension by restricting the derailleur's movement. When riding over rough ground, the weight of the chain makes a standard derailleur bounce up and down.
How are bike chains measured?
The chainstay length is the straight line distance between the centre of the bottom bracket axle and the centre of the rear dropout, so it's fairly easy to measure with a ruler.
What is bottom bracket height?
Bottom Bracket Height is a measurement taken vertically from the ground up to the center of the bottom bracket. This measurement will vary depending on the tire used on the bike.
What is a hanger on a bike?
A rear mech hanger is a sacrificial component part of a bicycle, designed to deliberately bend or break in order to limit or prevent damage to the bike frame and the other component parts of its drivetrain, when under duress.
