Borealis and Wolf Tooth Components have been collaborating on product ideas since the early days of both companies. The new front derailleur direct mount adapter for 190mm rear hub spacing is the first product that is a direct result of that collaboration. The adapter is designed and manufactured in Minneapolis MN just like all the other WTC products, and it has the finish and precision that WTC customers have come to expect.
Details: This new front derailleur direct mount adapter is lighter than other similar products and was designed for 190 mm rear hub bikes with long spindle 2X cranks like RF & Surly as well as the X9 fat bike crank when using the Wolf Tooth 2X fat offset spider that is soon to be released (note it does not work with the stock double X9). The clamp diameter is 34.9 mm and the offset is 49 mm.
