thats_a_five Posted August 6, 2012 Report Share Posted August 6, 2012 Hello, I picked up a TY250A twin shock a while ago for fun. Picked it up for only US$125. Runs like a dream, needed some TLC but that's part of the fun. I feel that the 14/53 sprockets have it geared too high for trials, OK for trail. I plan to change the front and see that Sunstar makes both 12 and 13 teeth options. What does anyone recommend? I ride Novice to Intermediate. Also, do I need to remove the left side cover to change the sprocket? Quote Link to comment Share on other sites More sharing options...
tony283 Posted August 6, 2012 Report Share Posted August 6, 2012 The Standard is a 13T but for modern day trials a 12T will be better. Yes, if you have a full coverage side cover. There is a key tab that must be flattened before undoing the nut which should not be too tight. Tony Quote Link to comment Share on other sites More sharing options...
thats_a_five Posted August 6, 2012 Author Report Share Posted August 6, 2012 Awesome, I was leaning toward the 12. Thanks Tony! Quote Link to comment Share on other sites More sharing options...
