If you're getting a Power2max NG with the Aldhu, what all do you need exactly to make it work? On a regular BSA frame (Track Elite)
Need the P2M spider, crankarms, the 147(?) road axle, and a BSA30 adapter? Is that right?
What the heck is the difference between the P2M Aldhu and the Aldhu24? Besides $100
Correct. To use the ALDHU system w/ a P2M power meter on a BSA 68 track bike you need the ALDHU crankarms, P2M spider, ALDHU ROAD axle, and BSA 30 ROAD bottom bracket.
The ALDHU uses a 30mm axle and the ALDHU 24 uses a 24mm axle.
The previous discussion is in the Effect of Crankarm Length thread.
