This is a table listing the Tensile Strength and Modulus of most of the grades of carbon fibre raw material used wordwide. You can use it to see how Toray T700 difers from Graphil MR40. As you will see there are many grades available with a large range of properties, using different grades in different locations helps tune the ride of the humble bicycle. The other to note that isn't listed in this table however is the elongation properties, basically the starting point is about 2% and it goes down as the modulus increases. This stuff is not very elastic!
