    Converting XX crank to 1x

    I decided to switch my Tallboy to a 1x10 and converted my XX crank using a Blackspire Snaggletooth 30T ring and a Praxis 11-40 cassette. All in, it was less than $200 using the existing crank and derailleur. The XO type 2 derailleur shifts smoothly in the stand. I'll find out how well it works on the trail tomorrow.

    I took the chewed up outer ring to the grinding wheel and converted it into a bash guard. Not too shabby.

    Turns out it took a few weeks and tweaks to get the shifting perfect. It was shifting ok for the first 8-10 rides, then it started sticking when dropping from the 28 to 24. I backed the B-tension off a bit and it's shifting better than ever.
