Shimano Crankset Tourney 501 170mm 48/38/28T 4-Arm 8S

The SHIMANO "FC-TY501" crankset is a set consisting of 3 chainrings that are attached to the crank with a square mount.
The crank length is 170mm and the set is compatible with 6, 7 and 8-speed drives.
This means it can be used on bikes with these drive systems.
The set also comes with a chain guard ring that is used to protect the chain from damage.

The chainrings have different sizes to cover the need for different gearing.
The sizes are 28, 38 and 48 teeth.
The set is made of aluminum and steel, giving it a good mix of strength and weight.
It is black and belongs to the TOURNEY group from SHIMANO.

The model number of the set is FC-TY501 and it has a chainline of 68/73mm.
The chainline indicates how far the chainring is from the center of the crank.
A wider chainline can provide more stability in some cases, while a narrower chainline can be easier to install.

The set is compatible with HG 6/7/8 speed chains, meaning it can be used with these chains.
It also has a riveted bolt circle, which means that the chainrings are attached to the crank using rivets.

The large, medium and small chainrings are made of steel.
The set is not designed as a 2-PIECE construction, which means that the chainrings cannot be mounted separately from each other. The chain line of the set is 47.5mm.

The set is suitable for use on mountain bikes and trekking bikes, i.e. bikes that are used off-road or on longer tours.
