Thanks for a very informative forum, I've learned a ton so far just lurking. I'm currently 6-2, 330lbs down from 350 since March, goal would be like 250. Former D1 college athlete so I understand my biofeedback pretty well by now. I run b/w 3-5 miles 3 times a week, do spin class once a week and have started mixing in a real ride on Saturdays. I have a Diamondback Insight 2 with all stock components.
I took it out for a 10 mile ride this weekend and noticed two things almost immediately. First, riding in tennis shoes is really inefficient but I doubt I'll have that sorted anytime soon. Second, I rode on a paved trail and I believe I've already knocked my rear wheel out of true. It makes a rubbing/whining noise every rotation. I'm hoping this can be fixed by loosening the rear brake cable to eliminate the rubbing? I'm hoping that's all it is, really don't want to have to replace a bent rim so early in this process. Any ideas on how to lessen the strain on my rear wheel?
Also, I'm signed up for a sprint triathlon in August, 400M swim, 15 mile bike, 5k run. Realizing I'll be riding a hybrid style bike not a fancy road style, any tips on building speed? Or does speed just come from time on the bike. The run and swim will be no problem, I do those distances already. I am worried about the bike but am hoping more time riding will solve that.
Anyways, thanks for all of the good information and good luck to everyone out there.
