xt m770 not touched the chainring bolts from new – need to change the middle ring quite urgently, got the t30 bit in the first 3 all came out, was majorly impressed, no major force needed!
then the last one, as i smugly started to turn, is completely tight 🙁
any ideas on how to get this bad boy out?? i dont have a heat gun nor soldering iron etc….
i do have a the chainring bolt tool, if i wedge that in the inner side of the rings, and apply some force with t30 on the front, is it more likely to budge? rather than just trying to loosen the t30 outer bit??
bloody typical this, everytime i attempt to fix something, it goes wrong 🙁
is there any spray etc that could get in and loosen it? ive tried wd40?
come on genius mechanic type bike folk! 🙂
