Road Bike Component Levels

Just like our buyer s guide to road bike groupsets this guide is designed to explain the components of a groupset and the different options offered by the two main manufacturers.
Road bike component levels. On modern mountain bikes the crankset consists of the crank arms chainrings the front cogs and the axle that connects the two crank arms. A road bike s groupset or gruppo refers to any mechanical or electronic parts that are involved in braking changing gear or the running of the drivetrain. The shimano road bike groupset hierarchy is as follows. Claris 2400 8 speed only sora 3500 9 speed only.
The crankset is what the bicycle pedals attach to and are what your legs spin in circles as you pedal. Being in my mid 50s the legs knees could use a break with the amount of climbing i do in my area. This 11 speed group is considered by many riders to be the best. Shimano 105 is the most affordable performance focused groupset from the japanese firm and comes on many mid market road bikes.
The tiagra is the 4600 you are talking about but was upgraded to the 4700 tiagra in 2015 after a much needed overhaul. We do it through low effort and precise shifting systems and through linear response braking systems that deliver superior power and modulation. The 2400 is a claris groupset which is on the bottom of the hierarchy for the road components offered. This results in smooth precise shift changes a drivetrain system with loss free propulsion and a braking system with high reliability.
Together they let the rider concentrate on the ride for stress free enjoyment. This was my first ever real road bike and the bike remains in excellent condition. Components of a groupset crankset.
