Custom cranks or special order cranks are something I will keep in mind. Hubby was thinking about the cranks on a 'bent bike and asked if I wanted to consider a recumbent trike in the meantime. I told him that for now I want to remain motivated to work towards turning the pedals on my diamond frame bike. I don't know how long it will be before I can--it could be within a month or it could be 3 months. I've been told by my ortho to expect to wait at least 6 months before I feel pretty good.
