Had a follow up with the doc this week. X-rays looked fine, and it's still a "wait and see" on the biceps. I may be hallucinating, but yesterday it seemed like there just might be some biceps involvement in some of my arm movement. It's hard to differentiate between use of the biceps itself, and having the surrounding muscles picking up the slack (left forearm getting bigger and bigger). But I think I feel a bit of tension on the biceps tendon, where it enters the elbow, when I try to use the biceps in a certain way. Time will tell.
Taking the TT bike in for crash repair today, since I don't want to mess with it one-handed. When I get that back, I'll move the SRM crank over to the race road bike and see how things feel in the lower position. My 6'7" step-son is riding some around the college campus on an old ill-fitting MTB, and I may give him the Gunnar. Mountain bikes on the road violate my sensibilities. It's like driving kids to school in a 4 wheel drive SUV.
