>>1830586There's a double hairpin near where I live.
Climbing them feels like you're in one of those TdF stages where the spectators can run to keep up with riders. You need the use of your lowest gearing, or else you're not getting up it. But at those slow speeds, you're keen to pick the least steep part of the hairpin.
Going down them, on the other hand, is hellish on a road bike. The geometry, stronger V brakes and wider tyres of a hybrid bike makes it unpleasant, but ultimately doable. On a road bike though, with rim brakes and 25mm tyres, I'm almost shitting myself, because almost all weight shifts to the front, and there's this feeling that I'm about to tip over head first. That's before realising that it's a hairpin and you're cornering sharply. Road bikes aren't designed for the kinds of sharp corners you find on a Mountain Bike Downhill trail. Even though it's paved, there's very little margin for error, and it's often covered in dirt after it rains.
There's that clip from the TdF of that guy... Pogacar? idk, he's chasing the rival for the race and he crashes after skidding on dirt on a sharp downhill corner. It's that kind of scenario that terrifies me about those kinds of roads.
