Which do you think is better, indoor or outdoor cycling? Indoor cycling seems pretty good for keeping you close to your maximum heart rate.
I'm older, so it's dangerous for me to do HIIT on the outdoor bike. I use the indoor bike for that. But the indoor bike doesn't do anything for balance, so I try to get out on the Cannondale 3-4 times a week....
That sounds like a great training method! What kind of Cannondale do you have? Is it a road or mountain bike?
A mountain bike, F6, I bought in 2008. One of the last ones make in the USA. Sturdy. I've taken several very bad falls on it, banged myself up good, but the bike has had only superficial damage...
Wow, that's impressive! It seems that they have moved their manufacturing and assembly overseas, to Vietnam and Taiwan. Do you think this has affected the quality?
According to a bike shop owner I know, yes. He still sells them, but he doesn't swear by them, like he did the pre-Asian Cannondales. They're still OK bikes, but they're not as much a bargain as they used to be...
That's really too bad. The Cannondale really revolutionized bike design back in the day.
Yes it did. The one I own is still chugging along! I expect it to be around for another decade or more if I take care of it.
Yeah, make sure to use the right tools! 
Heh, I wouldn't dare try to work on it myself, not without a Cannondale cert. I'll let the professionals do the tune-ups.
