Handling Corners?

That's how you'd do it in a closed course race. Not in the real world where oncoming traffic that you can't see on corner entry is ... at best, hugging the center line just as closely as the video depicts the rider doing ... at worst, well over the center line, as any of us know who've ever ridden or driven in hilly rural areas.

The fastest way around the corner just is not the safest way, not on a public roadway. Please. Be careful.

Consider that a speeding car driving in the opposite lane may invade your lane to clip the corner.

Ohh...I would like to see that chart too. My tires are 700x32 and max inflation is 95 psi. It doesn't give a range, so at 138 or so I like my tires at 80 psi. I think either Rivendell bike site has tire pressure range on it. I'll check & post it.

Here it is: http://www.rivbike.com/assets/full/0...ick_a_tire.pdf

Hope it's helpful.

Thanks for the websites. According to the rivbike site I need wider tires at 200-235 lbs. Mine are 23x700 and it recommends 28-32mm.

Any thoughts? And is that why I feel so unstable on my Madone? Wider tires feel safer but they don't feel fast.

If I go wider, any reccomendations on tires?

I HATE that corner Owlie ;)

Depends on whats the widest tire your bike will safely take. I tried running 28x700 tires, but my Ruby wouldn't take anything larger then a 25. Im about your size too, just run close @100-110 psi to prevent pinch flats.

I reinflate my tires before each ride, just to be on the safe side. I technically don't have to if I'm riding two days in a row. I'm about 136, my bike is probably around 25 pounds loaded, and I run my tires at about 105-10 for the back and slightly lower for the front. (My bike has 25s on it.)

I don't think most road bike brakes will take anything wider than 25s. And they won't take 25s comfortably (you have to deflate the tire most--if not all--of the way in order to get the wheel on and off). I don't have any recommendations--I'm still running the same tires that came with the bike (Kenda Kriteriums). Probably will go with something like a Continental Gatorskin...at least an all-weather tire so I won't be as worried about getting caught in the rain!
