Can be used to remove bike chain, rear rack, freewheel and crank. FLEXIBLE: It is long enough to give you enough leverage to install and remove bottom brackets with the force you need. ERGONOMIC DESIGN: Lever with beveled tip so it easily fits under the bead and spoke hooks to keep the lever in place. The bold shape makes holding and removing the tightest tires easy for anyone. PORTABLE AND EASY TO STORE: The small and lightweight outgoing tires can be tied together so you can easily find them while riding and continue everything. This feature makes these shift accessories stand out from their alternative shift levers. Used for Shimano SLX/XT/105/ULTEGRA BAS BB, XTR/DURA-ACE BAS BB.
