I'm planning on buying this 27+ rig here, a 2017 Pantera Expert ( http://www.gtbicycles.com/usa_en/2017/pantera-expert# ) with the idea that I can chuck some 29er wheels with it. I noticed that the rear runs 141*9 (weird, right?), how can I adapt an existing hub to fit this?
If it's a QR hub, you may be able to get a longer axle and some spacers depending on it's design. Most likely you'd need to get another 141x9 hub. This is the QR boost standard...yay!
