Ahoy ! I have just realized the need of a two-tine wrench to fit the chain ring nuts for a TA three-arm crank. The bolts are solid and do not permit use of a Shimano type wrench having a center locating pin. Is such a wrench available? Any suggestions other than taking screwdriver to the grinding wheel? I'd like to think there is general tool for this type of slotted nut.
Thanks.
