What to check before you buy

Handlebars, stems and seatposts are cheap to buy used but must be safe. Carbon bars and posts should be rejected if there is any scratch, gouge or crush mark from an over-tightened clamp, since carbon fails without warning. Check that alloy bars have not been bent, that the clamp areas are not scored, and that the stem bolts are not rounded. Confirm the clamp diameter (31.8 mm, 35 mm, 25.4 mm), the seatpost diameter and the steerer size for the stem, as these are not interchangeable.
