After continually being humbled on my local bike rides by hills that required me to drop into that 24" size 12 bi-pedal mode - I investigated the benefits of the all powerful compact crank - I did not know if it was going to work and being the cheap guy that I am I made an experimental alternative with available economical components - I have been so satisfied with my combination that I have not bothered to purchase a more prestigious brand name crank in its place...
