What Do You Get For $2,500?

Ok, so you’ve decided on a carbon fiber road bike – now, what kind of bike package can you get for under $2,500? There’s a balance that bike manufacturers need to maintain in order to keep within a certain budget figure.  We’ve listed out some of the best in terms of carbon frame, groupset and value for money.

Carbon Fiber Frame

Before we discuss the frames, we’ll explain the raw carbon fiber material.  It is made up of a long string of carbon atoms that have been bonded together.  It is known to be extremely stiff, strong, and light.  Perfect for making performance road bikes.  As with all bike parts, there’s different tiers of carbon fiber frames as well.  We’ll keep it simple here, but if you’re interested in what goes behind manufacturing carbon fiber, check out this link.

As a result of the material properties, carbon fiber is the top of the line material for frames. It’s far lighter than any of the metal frame options, making it the choice for speed and performance. Carbon fiber can also be moulded, which allows bike designers to build aerodynamic racing bikes. This is much more difficult with metal frames which are constrained with round metal tubes.

Most brands come up with their own buzzwords for their own proprietary carbon construction methods. Advanced Composite (Giant), BallisTec (Cannondale), FACT (Specialized) and OCLV (Trek) are all examples. Don’t get too hung up on these as most raw carbon fiber is produced by six companies.  It’s their engineering and design that determines the strength and stiffness of the carbon construction.  Here’s a good video that explains the various carbon fiber grades.

Groupset

As you continue to climb the price spectrum, you’ll expect to find better quality groupsets.

Entry-level bikes you’ll find that manufacturers mix and match to reduce costs. However, at the $2,500 range, bikes tend to have complete sets at around the mid-tier. For example with the Shimano groupset bikes, you’ll find the minimum to be a full Tiagra set on the Giant Defy Advanced 3.

The following are the major manufacturers and list of their groupsets from entry-level to top-end.

  • Shimano – Claris, Sora, Tiagra, 105, Ultegra and Dura-Ace
  • SRAM – Apex, Rival, Force and Red
  • Campagnolo (Campy) – Veloce, Centaur, Potenza, Chorus Record and Super Record

Weight

Think of this as an inverse relationship – the more you pay, the lighter you bike. You may also start to see features that were included on pro bikes a couple years ago as well. All in the name of speed and performance!

Entry level road bikes are generally 10+ kg, however bikes with a full carbon frame are likely to come in at the 8-9kg range.  We’ll go into more detail on each bike summary.
