This is our custom made carbon fork insert patterned after a similar insert made years ago for Alpha Q forks. Be aware this is custom made for us in one size 23.2 mm it is not customizable in any other diameter. It is not a replacement for the Alpha Q insert as these are smaller than the original insert. These inserts will work in Envy, Trek, Rockshox and other carbon forks with an ID greater than 23.2 mm. This insert is epoxyed (we recommend J B weld epoxy) into the steerer after the final length has been determined and the steerer has been cut. The advantages of these inserts are numerous; it reinforces the steerer tube, allows use of standard topcap and 6mm bolt, prevents the stem from crushing the steerer, and allows for easier headset adjustment. Unlike the original Alpha Q insert this insert is one piece with the 6mm threads part of the insert instead of a steel starfangled nut, also it will fit the above mentioned forks as the Alpha Q is too large to fit. The weight of this insert is 28 grams, with a 6x30mm bolt and Chris King topcap 44 grams, the total length on the insert is 100mm. Most expanding inserts weigh around 50 grams for comparison.
