any full assembly from the TA05 wont fit in the 415 as the front belt in the 415 runs down the centre, and the 05 is offset. So thats why they are putting the 05 pulley on the 415 spools and one ways. I think thats what you were asking??? Shouldnt matter if your using the spool or the oneway on the 415, you can still use the TA05 one way pulley on the 415 parts. I just bought a set of 415 pulleys a few weekends ago, and Keith Yu then shows me his MSX at a recent race event and tells me how much better the TA05 pulleys are on the MSX.... doh!
