Andrea, playing to your strengths is very important, but so is improving on your weaknesses. In the case of descending, going downhill in the drops is a perfectly acceptable alternative to the aero bars. In fact, it is much better in terms of control. At higher speeds, your reaction time is limited, but, more importantly, adjustments/changes are amplified. Thus, if you jerk the aero bars a little due to fear or seeing a rock or hole, you could actually cause and crash that the obstacle would not have caused. Being in the drops allows you to have greater control over the adjustments. @Coach_Flo will eventually get the descending video up, from our Cali ride, but there is a little bit at the 22:30 mark of this video: https://www.youtube.com/watch?v=BqbPSEFL0XQ&t=1374s
I don’t recommend that people do what I do, but I just want to show the differences. If you watch the video, I come out of the super tuck as the road ahead of me becomes uncertain. Throughout the ride, I changed my position based on road quality, speed, traffic, etc. Everything is situational dependent, and I do not tie myself to a position for anything.
As for bracing, that is a big no-no. If you brace for a crash when approaching debris, a hole, a turn, or whatever, you are increasing your chances of fulfilling that prophecy. When you brace, you tense up. That means movements are not fluid, and you fixate on the place you do not want to be. There are two keys to getting through crashes in front of you, tight turns, road issues, etc. First, as discussed earlier, look where you want to go. That means you need to not look at the carnage. Look for the clean road or open space. Second, relax. That doesn’t mean kick back and chill. It just means to have a firm but not tight grip on the bars (to avoid slipping off the handle bars if you cannot avoid hitting the hole, object, or whatever), keep a slight bend in the elbows, as locking out will make your jerky, and keep the knees soft. Keeping the knees soft means not clenching the glutes and thighs. This will help absorb some of the impact of whatever you hit and let the bike bounce underneath you a little bit. GCN did an episode on how to ride the cobbles where they cover some of this.
If you hit the hole or debris, get through it before making any major corrections. Do not slam on the brakes or jerk the bars trying to get back on your old line. Stop pedaling briefly if you need to collect yourself and take stock of you and your bike. As happened to me the other day, I hit a big pothole in my aero bars because my mind had drifted. The bars tilted downward a little because of where my weight was when my front wheel made impact. I quickly recovered and just levered my bars back into position without stopping. If you aren’t comfortable doing something like that, stop and make the adjustment on the side of the road. Then, get back at it.
From my experience racing on crap roads, these techniques have helped me stay upright on occasions when others have gone down. When you couple this with riding within in your skill limits and being conservative in crappy weather, you have a much better chance of not going down.
