cranks won't necessarily give you speed but if you're looking for a great crank for racing you can't go wrong with a set of Profiles, and if you're of average heigth 180mm is better for power and 175mm is going to allow you to spin a little bit quicker but won't give you the power the 180mm would.

I would totally go with Profile race cranks.. they are like 120 and have a lifetime warrenty on breaking and bending.. good thing.. I snapped my crank arm a month ago and they switched it, no problem. Totally profile.

They are just about top stuff so go for it if you can aford it. If not look for a nice heat treated crank. Warrenties are good to have, it means they have a good amount of trust in their product.
