Giant TCR Aero Carbon fork for road race bikes. 1 inch steerer tube diameter. Weighs in at just under 1.5lbs. The steerer tube is 170mm, or 6.69 inches. The total length of the fork is 545mm, or 21.4 inches. Steerer is aluminum, and the fork is in great shape, with minimal scratches and blemishes. A 28c tire will fit, with about 3mm of clearance from the top of the fork, so i suggest you run 25c tires or below. I purchased this fork for my project build, but the steerer tube is too short for my frame. This is a GREAT CARBON FORK that will lighten the front end of your bike significantly if you have a steel fork, and dampen the vibrations of the road on those speed rides.... or would be a great part to go with a custom build. Carbon forks aren’t cheap, so take advantage of this sale while it’s available!
