    Niner Sir 9

    Planning on getting a MTB after almost 20 years riding exclusively on road. I started riding gravel last year, and now want to do more MTB.

    Nothing too crazy. Easy singletrack, fire roads and building up to do bikepacking in a year. I'm not intending to go fast, I do intend to go far.

    I initially wanted to go Ti (Salsa Timberjack or Lynskey LiveWire), but the more I looked at the geometry (and price) of the Sir 9, I figured it was more aligned with the type of riding I wanted to do.

    What are your general opinions on the Sir 9?

    What is sizing like? I'm about 5' 11'' with a shorter 31" inseam. Which according to the Niner website is a Medium. That right?

    Thanks!

    I've had my medium Sir 9 for about a year. It's not my mountain bike as I have it set up more like a cruiser. I'm a little over 5'8" with a 30" inseam and I always ride mediums. I've got a 60mm stem on mine and I really like the fit. Despite the set up it's comfortable for long road or gravel rides. I think a medium is going to be too small for you. I would go for a large if I was you.Niner Sir 9-img_6213.jpg

    Thanks! Iím leaning towards a Large now, and more so after going through the Niner geo charts the last few days.

    I had an MCR9 from 2007. Size L. It is the smallest I can ride at 6'-3", with a 90mm stem and 400mm seat post. I thought it was a great bike, but it is not recommended for hard hits like AM riding. For XC it is a great bike. "M"agic "C"arpet "R"ide is a legit description. The SIR is the same frame.

    Ordered the frame. Should be here in a week.

    Now the next big decision....wheel size.

    I think Iím going to try 27.5 x 2.8Ē

    If I was already bikepacking, I probably would have gone 29, but the sandy/rocky trails in my area would be better with the wider 27.5s, I think.
