Wheel Rear for Adults: 26x2.125 STL CP 36 STL FW 5/6/7sp 12gUCP

The bicycle you described has the following key components:

The wheels are 26 inches in diameter and 2.125 inches wide, with a steel construction. The crankset is a 36-tooth chainring, and the freewheel has 5, 6, or 7 speeds. The bottom bracket is a 12-gauge, 26x2.125 size.

The frame is constructed of steel, with a 3/8-inch diameter bottom bracket shell. The bike has a steel fork as well.

Overall, this appears to be a relatively standard mountain or hybrid bicycle configuration, with durable steel components throughout. The wide tires and multi-speed freewheel suggest it is designed for a mix of on-road and off-road use.

The key specifications are:

• Wheel size: 26 x 2.125 inches
• Crankset: 36-tooth steel chainring
• Freewheel: 5/6/7 speed
• Bottom bracket: 12-gauge, 26 x 2.125
• Frame and fork: Steel construction
• Bottom bracket shell diameter: 3/8 inch

This balanced configuration should provide a comfortable, capable, and relatively low-maintenance bicycle suitable for a variety of terrain and riding conditions. The steel frame and components also suggest it is built to withstand regular use and abuse.
