VenmoNiner SIR9
Steel
Is
Real
Billed as a "do-it-most" bike, this is a premium 853 steel hardtail mountain bike, known for it's prowess as an XC racer which can also be used for bikepacking and other outdoor adventures. It is snappy with awesome power transfer and climbs like a pro. This is a size medium. It is priced for a novice who wants to start off with a great bike, a NICA racer, or a rider who wants to up their game on race day, or step off of a full suspension once in a while. And !BONUS! it has an eccentric bottom bracket so you could run it as a Single Speed if that is your jam!
