aarn 144# PRO chainring
❌ SOLD OUT
The aarn PRO chainring commemorates the 10th anniversary (or 12th, depending on how you're counting) of aarn bicycle components. First developed in 2008, tested and run in 2009, and sold starting in 2011 in a run of 50pcs under the original marking "44rn".
Like all arrn chainrings, this version is manufactured to the highest standards and features a specially developed coating, infusing Teflon® particles into a bronze/titanium color type III hardcoat anodized finish, with the goal of reducing friction and improving wear.
This series features an prismatic holographic logo, and come in a reusable custom poly-weave zippered bag.
