Are you sure you ride a 61cm? 61-62cm tends to be the largest "stock" frames from most manufactures.

I only say this because I'm 6'4" and ride a 65-66cm. I'd get a proper measurement, maybe take a look at the RBW method of frame sizing and give it some serious thought: http://www.rivbike.com/article/bike_...g_a_frame_size

I'm much happier on a 65-66cm than I was on a 61-62cm. Do it right the first time and get a frame that fits you.
