KUbikes offer various components to choose .
If you are unsure which components are best suited for your desired application, we would like to support you in your choice with the following explanations:

Tires
- Schwalbe Black Jack 20 x 1.90: MTB tires for terrain and unpaved paths. Super grip thanks to many tread blocks and best suspension comfort thanks to large air volume.
- Kenda APTOR 20 x 1.75: all-round tire, ideal for asphalt and light terrain. Very light tire with good rolling properties.
- Schwalbe Little Joe 20 x 1.40: All-round tire, ideal for asphalt and paved paths. Narrow, very light tire with very good rolling properties.
Schwalbe Little Joe 20 x 2.0: Very wide MTB tire for off-road and unpaved paths. great grip

Fork
- Rigid fork: made of aluminum or carbon
- Suspension fork : Spinner 300 AIR, travel 80 mm, with lockout

Brakes
- Shimano disc brakes: very smooth-running hydraulic disc brakes with a good pressure point
- Magura MT4 disc brake: very smooth-running hydraulic disc brake, minimal hand force for very good braking effect, minimal weight

Crank /Chainring
- KUbikes aluminum crank, chainring with 28 teeth: Lightest possible gear, enables riding in extremely steep terrain. Pedaling is therefore not always possible when driving downhill. Moderate top speed. Chainring with a special tooth shape that keeps the chain better on the chainring (narrow/wide). Decreases the possibility of dropping the chain
- KUbikes aluminum crank, chainring with 32 teeth: heavier gear than chainring with 28 teeth, enables riding at a higher top speed. Gradeability reduced when driving uphill. Chainring with a special tooth shape that keeps the chain better on the chainring (narrow/wide). Decreases the possibility of dropping the chain

Saddle / Seat post
- 52parts: narrow ergonomic shape, comfortable padding. Seat post aluminum.
- KUbikes Carbon: super light; narrow shape. Carbon seat post.

Seat clamp
- Without quick release: bolt with hexagon socket, tool required to adjust the saddle height, therefore theft-proof to a limited extent
- Quick release: tool-free adjustment of the saddle height and therefore quick adjustment possible at any time

Wheelset
- KUbikes 20 performance: NOVATEC hub red anodized, spokes black, nipples aluminum red, rim 52parts aluminum black (inner width: 23 mm); Wheelset weight: 1.56 kg
- KUbikes 20 SL: 52parts hub red anodized, spokes black butted (2.0 mm - 1.5 mm - 2.0 mm), nipples aluminum red, rim 52parts aluminum black (inner width: 18 mm); Wheelset weight: 1.05 kg
