custom carbon fork insert

Pictured below is our custom made carbon fork insert patterned after a similar insert made for Alpha Q forks. These inserts will work in Reynolds, Easton, and other carbon forks with an ID greater than 22.7 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 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. The Reynolds expanding insert weighs 46 grams for comparison. If you want to buy one of these inserts send off a email to bikewiz (at) cornercycle.com (replace at with @) price per insert is $40. This insert will cure a lot of problems associated with other methods of headset adjustment.
