    Comments about Blackspire Twinty BB Mount Chainguide:

    I bought the smaller BB mount Twinty. I am using a 22/32 chainring setup and 9 speed on the back. My advice based on my experience using this on a 2 x 9 setup is to slid the guide/tension block the whole way to the rear. Equally important is where you index (time) the overall position of the guide. Looking at the drive side (guide), I found it worked best to move it more counter clockwise to lessen the tension on the chain. I should mention that the bike I mounted this guide on is used primarily as a carefully ridden cross country/all mountain bike. When adjusted properly it has been working well. I must mention that I have not used it a long time and the weather and conditions I used it in were clear and dry
