Cross-country bike Retroglide seven

It’s a good and fancy bike. It’s a cross-country bike, you can use it in the city but also in the mountains. I bought it from Silicon Valley Bicycle Exchange in January 2023. The tires and tubes are 27.5 in. The shifting is 1 gear at the front and the rear gears are 8. Everything is working, the chain is a little rusty, but it works.
Wheel Size: 27.5 in.
