Sean S.wrote a review of Yakima T-Axle Fork Adapter 20mm on November 6, 2010
I bought this (with my fingers crossed) to work with my original style Boa system. It worked fine, the quick release had to be screwed all the way in but it held just fine. All the picks show this item with the newer rack systems, don't worry, it works.
**side note: Fork Up is the actual manufacturer, and when I looked they were charging more for the item and for the shipping, buying direct wasn't worth it.
