What's a bailout gear?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Dino,

I rode up Goshen Street yesterday. Strava said it was less than 10 percent. Maybe you're using the word grade differently? I ride up Via Capri (back side of Mt .Soledad) daily, and the same Strava app says Via Capri is 13.3 %.

Grade is correctly calculated as the ratio of the rise to the run, or horizontal distance covered. On shallow grades the run will be close to the distance measured along the slope, but as the grade gets steeper the numbers deviate considerably. For example a 100% grade isn't vertical as it would be if measured along the road. It's only 45° since the rise is equal to the run.

For those who care about angles, the grade is the tangent of the slope angle expressed as a percentage.

Jiggle,

Thanks for the distinction, it explains alot. Whether someone posted to an old thread or not, I would not know this unless he did so.

In other words you're better off riding in your lowest gear to start, than riding in a too high of gear, just to preserve a "bailout gear."
I agree. A bailout gear usually needed because of being too optimistic early on in the climb. I am a zero climber, which lowers other rider’s expectations of my equipment choice of the cassette I use. I do get dropped on that first big surge that happens, but it I keep my legs turning, I can usually not lose anymore time after the group up front settles down. A lot of times, if the climb is long enough, I will reel in the guys who blew themselves apart trying to stay with the lead group.

But at what speed do you just fall over because you're not going fast enough?

I don't think AEO can hear you- last post almost a decade ago.

My upper legs were always pretty muscular, but the muscles themselves were not especially defined. Now when I walk by the mirror in the bedroom I think out loud, "are those MY guads!?" And then my wife rolls her eyes and tells me I need to do some sit ups.
Riding up (long and steep grades at least) hills have more to do with aerobic capacity than it does muscle development. When riding on flat roads, a heavy rider maintains more momentum than when riding up a steep climb. Climbs are constant resistance, where riding on the flats, a rider can soft pedal here and there and not lose much in the way of forward momentum.

I know.. I wanted to make sure he had enough time to get to the top of the hill and return home.

Using nowadays affordable technology/terminology:

my bailout gear: 34 x 28
20 min FTP: ~3.1 watts per kg
I can climb continuous 15% grade (no break) for ~0.4 miles. But no longer no steeper than that.
