I've been shifting before the turn going into an easier turn to spin out of the turn before I was going into the turn and not shifting and then going out pushing a big gear, neither worked well. I think I just have a lot of work to do on my legs, I've only been riding about 10-12 months and I've only been riding consistently hard since Sept. Once the crit gets going I rarely can stand out of the saddle and just crank it like crazy. I'm just trying not to rush anything, but I'm very competitive so I get frustrated.
