If you have a high quality frame that you adore and it requires a braze-on clamp adapter for the front derailleur, this is most likely the clamp you want. K-Edge designers and machinists went to great lengths to produce these clamps to the tightest tolerances, so when you clamp them to your prized frame, it will fit with absolute precision.

Being a K-Edge product, it's no surprise that it is entirely machined from a solid chunk of 6061-T6 alloy. It is then polished and anodized to complete the job. The tolerances are so tight that the hinge and pin open and close effortlessly. These are available in 31.8mm and 34.9mm diameters and in different color options. Make sure you choose the correct fitment for your frame and the color you prefer.
