Hi Gents and Gals.

I have been riding for nearly a year and have given my bike a pretty good hiding over the year. My bike is entry level and i have killed my brakes. I have come to look for new calipers and the choice is amazing. I have settled for shimano 105's at £29.99 each from chain reaction cycles. How do I tell if my bike has 49mm or 57mm drop? I can't find info on the Python website. any help before I buy the wrong ones!
