Keepin’ it real with steel
Oct 2018
I have to admit — I am somewhat of a crusty old dude and sometimes resist change until it has been thoroughly tested by others. This being the case, I was a bit doubtful when I first climbed on the Niner SIR 9, a steel hardtail that can run 27.5-plus or 29-inch wheels. The 27.5x 2.80 tires seemed like overkill compared to my super-light 29er race bike, and the thought of riding a bike that wasn’t fully suspended had me questioning my sanity.
