TA hasn't changed their crank axle lengths. The 123mm Phll(old #4 ) is a match for the old #373 TA crank axle. Phil still makes a #5 125mm( The TA #374 length) as well as 127.mm and 130mm. With the Phil You can adjust the spindle offset with the cups or in the assembly of the crankbearing (shop job). With all due respect beer can shims can keep the worn out crankarms working on the junk bike but for your new quality stuff just buy the right parts. T.Shaw Santa Clara,California where we drink less beer in the bike shop than we did 30 years ago!
