I have Logic cantis
Is that Specialites TA chainring?
Do you have craked seattube, I dont...
Yeah my seattube was cracked... like Martin says, just cut below the crack and he/I/we/they just mounted a 3 quid 31.8 seatclamp on. Works a charm and nothing to worry about ( a cracked fork or headtube would be far far faaaaaaaaaaaaaaaaaaaaaar worse
Anywayz, yeah I have one TA chainring up front... a 48 tooth one, and in black to keep the black/silver a bit balanced. Also have a black M730 crank with silver BioPace chainrings, but that's going on my Rascal. I had two TA chainring at first, so only the small ring would be silver and the two TA rings are black (24/36/48 ratio).
Problem was, with those two chainrings installed the chain would "rattle" against the 48T chainring when in the middle ring up front and on the two smallest cogs in back
Too bad, but when I changed the middle ring for an old Shimano I had the problem went away. So I guess those TA rings are thinner than a Shimano
