I mainly used the bike for shopping and for trips in the nearby area. For autumn and winter use, I have special 'winter tires' with studs, and in summer, slicks. These are included in the sale price. Recently, I had the brake disc replaced; otherwise, the bike has been serviced every year. Unfortunately, I no longer have the original receipt, and the frame number can no longer be read (it's a sticker on the frame). Unfortunately, I also did not register the bike with Trek.
