Hey guys just after a bit if help. Trying to do some maintenance to my 2015 session 88 and have some questions. First off I am wanting to replace my bottom bracket and crank set. What type of bb is that frame running. And what speacil tool will I need for the removal and install of the bearings. Second question I have movement in my detailer hanger and it appears to be from the mounting point onto the drop out how do u replace this.
