What to look for in the material of a bike frame 

A bicycle can be made using a variety of materials. The most common materials used to build a bicycle are:

Steel: It has traditionally been the most widely used material for bicycles. Steel offers excellent strength and durability, and is relatively inexpensive to produce. However, it can be heavier than other more modern materials.

Aluminum: Aluminum is a lightweight and strong material that has become very popular in bicycle manufacturing. It offers a good ratio of weight to strength, and is relatively inexpensive. Aluminum bicycles are common among both amateur and professional cyclists.

Carbon Fiber: Carbon fiber is a composite material that offers an excellent combination of lightness and stiffness. Carbon fiber bicycles are extremely lightweight and can provide excellent responsiveness and performance. However, carbon fiber can be expensive to manufacture and repair.

Titanium: Titanium is a very durable and lightweight material, but it is also expensive. Titanium bicycles are valued for their durability, comfort, and resistance to corrosion. They are often chosen by enthusiast and professional cyclists.

Light alloys: There are also several light alloys used in bicycle construction, such as magnesium or light titanium alloys. These materials offer good strength and light weight, but they can be expensive.

It is important to note that many bicycle manufacturers use a combination of materials to achieve an optimal balance between weight, stiffness, strength, and cost. The choice of material will often depend on the intended use of the bicycle, the buyer's budget, and personal preference.

One of the most important criteria when buying a road bike frame is the choice of frame material. A carbon road bike frame differs significantly from an aluminum, steel, or titanium road bike frame in appearance, composition, and riding characteristics. Each material has certain advantages and disadvantages. That's why in the end it is decisive to which features you place particular value. Here you can find an overview of what distinguishes the various materials:

Carbon road bike frames

  • the material par excellence: lightweight, rigid and comfortable where needed
  • Enables creative designs and fluid, streamlined shapes without compromising weight and stability
  • High acquisition costs and less robust than metals

Steel racing bike frames

  • extremely durable, sturdy when properly cared for
  • elegant aesthetics
  • Comfortable and "lively" driving experience
  • relatively high weight

Aluminum road bike frames

  • very light, rigid and responsive
  • Less durable than steel and titanium, but stronger than carbon
  • excellent value for money

Titanium racing bike frames

  • subtle aesthetics, noble finish
  • Extremely durable, tough and corrosion resistant
  • Unique ride comfort and "lively" handling
  • Lighter than steel, but also more expensive

Standard/Dimensions for mounting on the racing bike frame.

When choosing your road bike frame you should be aware that frames have different standards and mounting dimensions. For example, a frame set for skid brakes cannot be converted to disc brakes. Similarly, the choice of gear set and tire width affects frame specifications. Therefore, before buying a road bike frame, you should pay attention to the following things.

Axis standard and mounting width

Until recently, all road bikes had open dropouts for quick-release axles. With the introduction of disc brakes, closed dropouts and 12 mm or, more rarely, 15 mm through axles were introduced - standard installation widths: 100 mm in front and 135 or 142 mm in back.

Internal bearings/ bottom bracket

BSA, ITA, T47 (screwed), pressfit or something completely different? The installation size should also be observed here. In addition, the choice of inner bearing goes hand in hand with the choice of crank: because the inner diameter of the bearings must match the diameter of the crankshaft.

earphone

With classic threaded head sets, a distinction is made between the three sizes of 1″ shank, 1″ 1/8 shank, and 1″ 1/4 shank.
In the case of threadless head sets, a basic distinction is made between these different types:
  • Outer cup (EC) - outer bearings and half-bearings
  • Zero Stack (ZS) - semi-integrated bearings and semi-bearings
  • Integrated (IS) - fully integrated drop-in bearings (no shells)
S.H.I.S. (Standardized Headset Identification System) helps you find the right type of headset for you.

Diameter of seat tube/right seatpost and seatpost clamp

Often a seat clamp is already included with the frame. Some manufacturers use their own seatpost design (not round). In this case, the choice of seatpost is limited to the frame manufacturer.

Compatibility of additional parts

Should your new road bike frame be suitable for weld-on or clamp-on front derailleurs?
How many options do you need to mount a bottle cage?
Do you prefer an internal cable guide for a clean look or classic, easier-to-maintain external cables?
Would you like to take your road bike on multi-day tours with an overnight stay? Then you should make sure there are eyes for roof racks and fenders.

What distinguishes a road bike frame from a gravel and cyclocross frame?

Uomotre classic road bikes are designed for maximum performance on the road, cyclocross and gravel bikes are designed for off-road use. This has an impact on the geometry and equipment of a Gravel or Cyclocross frame:
  • Tire widths of about 40 mm are common for gravel bikes and between 32 and 35 mm for cyclocross bikes.
  • The frame should allow a corresponding amount of tire freedom.
  • To achieve greater ground clearance, Gravel and Cyclocross frames have a raised bottom bracket.
  • The wheelbase of a Gravelbike is quite long, the Cyclocross frame has a shorter wheelbase than other bikes with road handlebars
  • Road bike and cyclocross frames are mainly lightweight and have a very sporty frame geometry, Gravel frames are generally designed to be stronger and more comfortable (longer head tube and less saddle camber)
  • Gravel frames in particular have, in addition to fender mounts, many eyelets for roof racks and bottle cages.
