So glad to hear their are other newbies out there gripping for dear life!
I learned to ride last year on a hybrid (definitely easier for a terrified new rider) and I remember braking constantly and holding so tight, I went through 2 pair of padded gloves.

This year I bought a road bike, and I'm going through it all over again as I transition. I'm gripping too hard, braking all the time and feeling, once again, like I could easily end up in the ditch when cars or other riders pass by.

I'm confident that one day I'll feel as comfortable on this bike, as I grew to be on my hybrid. I just need to keep getting back in the saddle (20 miles every Saturday and Sunday!)
