Review on πŸ”© Eigertec Crank Arm Screws: High-Performance 7075 Aluminum Alloy Crankset Arm Bolts for Shimano M20 by Charles Palma

Revainrating 2 out of 5

Wrong size for most Tech II hollow cranks

The flange diameter of the M8000 crank is correct, but the threads are too big, about a millimeter longer. On the RX810 crank, the flange diameter is about 2.5mm larger. Thread depth is ok. On the R8000 crank, the flange diameter is again too large, by about 2.5mm. depth is ok.

Pros
  • Alright!
Cons
  • Not bad
