Need help with bike situation
Hello all, I am new here to the bike radar forum. I have some issues and was wondering if someone can give me some advice. I'm 5 feet 11 inches tall with the arm span of 76 in. I've been mountain biking for about a year and I've had several different bikes. I currently have a 2017 Niner rip 9 RDO but it's an XL and comfort wise it fits, height wise it don't. It is the higher-end with the fox suspension and the Eagle One by 12. I'm having trouble with the bike and I have an option of getting the new 2018 Scott genius 920 and trade. Would this be considered a downgrade considering my Niner is top-of-the-line everything or is the 2018 suspension somewhat decent. Of course the Scott will be in a large frame. Is there anything I can do with having way too long arms for my height make me more comfortable on the large, or am I just screwed. Any advice would be helpful.
