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 I know what type of crankset I have?

Crank length: This is measured from the centre of the bottom bracket axle to the centre of the pedal axle. Most stock bikes have cranks of 170mm or 175mm, but you can get them as short as 140mm and as long as 190mm. Choose crank arms that suit your inside leg measurement for optimum comfort and control.

Are Shimano cranks interchangeable?

Shimano road cranks are interchangeable between other component levels that utilize the dual pinch bolt. Nearly all pinch-bolt style Shimano road cranks are able to be interchanged in equivalent lengths.

Are MTB cranks universal?

No, cranks are not generally always interchangeable, but you probably can transplant the crank from the broken bike. First, do both bikes have 6, 7 or 8 sprockets in the rear cluster? If so, they use the same chain width and the spacing between the chainrings will be the same.

What is a MTB crank?

What is a crank? In case you’re new to this, let’s start with the basics: cranks are the components that transmit power from the pedal to the chainring. The two cranks, left and right, are connected to the pedals and to each other through the bottom bracket axle.

What is a bike crank arm?

Bike crankarms transfer your pedaling power by connecting the pedal to the bottom bracket and forward gearing. Crank arms act as a rotating crank, part of the crankset, allowing the rider to apply force to the pedal transferred via the crank arm to the forward gears to drive the bicycle chain.

Are all bike cranks the same size?

Why are standard cranks the length they are? The three most common crank lengths for bicycles are 170mm, 172.5mm and 175mm. What size your bike has will likely depend on what size the frame is. Small bikes tend to come with 170mm cranks, medium with 172.5mm and large with 175mm.

Hollowtech = Winner

In short, the advantages of Hollowtech bottom brackets over Octalink are: Lighter bottom bracket and cranks. Lighter, stiffer spindle. The same bottom bracket can be used on different bike types.

How important is bottom bracket?

Bottom bracket stiffness is super important. Besides avoiding plastic and unnecessary parts, you want to look at a bottom bracket with a wide bearing stance. The closer the bearings are to the crank arms, the wider the base for your spindle to rest on.

How do I know if my bottom bracket needs replacing?

To check if your BB needs replacing, drop the chain off of the smallest chainring and spin the cranks. If there’s a side-to-side wobble, or feeling of grittiness, it’s time for a new one.

How do I know what size my bottom bracket is?

To find out the size of bottom bracket needed, measure the inside of the bottom bracket shell in your frame, it will be 73mm, 70mm or 68mm. Some older frames may have Italian threaded bottom brackets, instead of the more modern English.

What is Cotterless crank?

The term cotterless cranks refers to all crank models that do not attach to the bottom bracket spindle via a wedge. The attachment mechanism of cotterless cranks depends on the bottom bracket. For example, square taper bottom brackets connect to the cranks via a set of bolts threaded into the bottom bracket axle.

Are all crank arms compatible?

While modern road cranks are compatible with many different types of bottom bracket shells, some combinations are better than others. Shimano (left) and GXP (right) crank axles share the same diameter — 24mm — however the end of each axle is quite distinct.

What is the difference between crankset sizes?

The crank length represents the distance between the centre of the bottom bracket and the centre of the pedal axis. The most common lengths are 170, 172.5 and 175 mm, but it is possible to find cranks between 165 and 180 mm in the market.

Do all chainrings fit all cranks?

What is the difference between 172.5 and 175 cranks?

From 172.5mm to 175mm, you have only 2.5mm difference. We set our saddle height when the pedal is at 6 o’clock position. So you should lower the saddle for 2.5mm, since your pedal is 2.5mm lower than it was.
