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.
- The chainstay is a pair of metal tubes on the bike frame that connects the bottom bracket to the rear axle holders. The chainstay connects the bottom bracket to the center of the back wheel.

What does a chainstay do?
Olsen describes the purpose of the chainstay as “locking in place” the rear axle. “With every pedal stroke, the bike is trying to twist the rear axle. If you look from the top of the bike, it’s trying to twist the rear axle anti-clockwise and compress the driveside chainstay.”
What is a rear chainstay on a bike?
The chainstay is a pair of metal tubes on the bike frame that connects the bottom bracket to the rear axle holders. The chainstay connects the bottom bracket to the center of the back wheel.
How does chainstay length affect ride?
The shorter the chainstays, the closer the rear wheel is to you, and the easier it is to get your weight behind it which is what happens during tricks like bunny hops, wheelies, manuals, and drops. For that reason, BMXs, dirt jumpers, and free ride bikes have short chainstays.
What are the stays on a bike?
Terms from diagram above: Seat Stays: The seat stays are part of the bicycle frame. They connect the rear wheel to the seat tube. Chain Stays: These are also part of the frame and they connect the rear wheel to the bottom bracket/crank.
What is considered a short chainstay?
For 26″ and 27.5″ full suspension bikes, something between 420mm and 430mm would be considered short, while for a 29er, something in the mid 430’s would be considered short. And then for hardtails, stays can be as short at 400mm for smaller wheels.
What is a low trail bike?
“Low-trail” bikes, designed to carry cargo on the front of the bike, have a trail figure of less than 45mm. Mechanical Trail (Front Normal Trail), describes the distance between the point where the front tire contacts the ground and the steering axis, measured perpendicular to the steering axis.
What is a BMX chainstay?
One of the most important specs on a BMX frame, is the chain stay. Your chain stay connects at the bottom bracket and runs all the way to the rear wheel. Usually, the distance can vary from 12.5″ to 14″. Choosing the right chain stay will help with certain tricks and ultimately enhance your riding.
What is chainstay angle?
Chain stay angle generally refers to the angle from the rear axle to the center of the bottom bracket. This measurement refers to the actual angle from the rear end of the chain stay to the front end of the chain stay.
What is trail on a bike?
Trail is best thought of as the tire patch “trailing” behind the steering axis. Fork offset for road bikes usually ranges from 40 to 55 mm, generating trail figures from 50 to 63 mm. 57mm of trail is considered by many to be an ideal combination of stability and agility.
Why is chainstay length important?
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. With more than 30,000 custom bikes designed and built, we think we bring unique experience to each new bike project.
What is chainstay length on a mountain bike?
3. Chainstay length. Or, more accurately, the rear centre. This is the horizontal measurement between the centre of the rear wheel and the centre of the BB.
What is known as the cockpit of the bike?
The cockpit components include all the contact points between rider and bike – handlebars, saddle and pedals. Also in this category are the other essential parts including headsets and seatposts.
What is a Dropped seat stay?
Bikes designed to be comfortable yet fast, stiff and light. Bike designers point towards a smaller rear triangle, achieved by dropping the seat stays further down the seat tube, as a way of increasing comfort. When the saddle is pushed down, it flexes the seat post and this, in turn, tries to bend the seat tube.
How can I tell what frame my bike is?
Place the end of a tape measure at the exact center point of the gear crank (the metal post that runs through the center of the bike’s chain sprocket). Then run the tape measure up to the top of the tube. Measure to the point where the tube ends. This will give you the length of the seat tube which is the frame size.
