A couple weeks ago I changed my chain and sprockets out. I put on a 16T on the front and a 46T on the back. Both are Steel JT Sprockets. I had read up on this forum that there may be some rubbing on the chain guard but that it would go away after a little bit. I'm still hearing it rub when accelerating around 2.5-3.5K. I have the slack set to 25mm. I was wondering if anyone else experienced this. I'm thinking about going the opposite way and going with a 15/43 set up instead, anyone whose done this did you have to take any links out? and if so how many?
