Question 1

Why is aerodynamics so crucial for track bike wheels?

Accepted Answer

In the competitive environment of velodromes, every fraction of a second counts. The aerodynamics of the wheels reduce air resistance, allowing the cyclist to reach higher speeds with less effort. Profiled rims, as well as solid wheels with lenticular flanges, are often preferred to minimize this resistance and optimize speed.

Question 2

How important is wheel stiffness in track sprints?

Accepted Answer

Stiffness plays a crucial role, especially during explosive sprints. A stiff wheel efficiently transfers pedaling power to the track without energy loss due to wheel flex. This allows for rapid acceleration and the maintenance of speed. Materials such as carbon are often chosen for their combination of stiffness and lightness.

Question 3

Fixed-gear vs. freewheel: What's the difference on the track?

Accepted Answer

On velodromes, bikes are equipped with fixed-gear wheels, which means the pedals are always moving as long as the wheel is turning. This setup gives the rider total control, allowing for quick speed adjustments and a better connection with the bike. The freewheel, on the other hand, allows the pedals to remain stationary even when the wheel is moving, but this feature is not preferred in track cycling.

Question 4

Why is aerodynamics so crucial for track bicycle wheels?

Accepted Answer

In the competitive environment of velodromes, every fraction of a second counts. The aerodynamics of the wheels reduce air resistance, allowing the rider to reach higher speeds with less effort. Profiled rims, as well as solid wheels with lenticular discs, are often favored to minimize drag and maximize speed.

Question 5

Why is wheel stiffness important in track sprints?

Accepted Answer

Stiffness plays a crucial role, especially during explosive sprints. A stiff wheel efficiently transfers pedaling power to the track, minimizing energy loss caused by wheel flex. This results in faster acceleration and better speed maintenance. Materials such as carbon are often chosen for their ideal combination of stiffness and lightness.

Question 6

Fixed-gear vs. freewheel wheels: what’s the difference on the track?

Accepted Answer

On velodromes, bikes are equipped with fixed-gear wheels, meaning the pedals keep moving as long as the wheel is turning. This setup gives the rider full control, allowing quick speed adjustments and a stronger sense of connection with the bike. A freewheel, on the other hand, allows the pedals to remain stationary while the wheel is still moving — but this feature is not favored in the track environment.

Question 7

Can I use a lenticular wheel on the front during a race?

Accepted Answer

It depends on the event and the rules (UCI/organizer). Some setups are allowed under certain conditions, while others are not, depending on the discipline. The right thing to do: check the race/velodrome rules before showing up with a “full aero” setup.

Question 8

How do I choose between the iO, Comète Track, and Ellipse?

Accepted Answer

iO: prioritizes time trial/speed, aerodynamics + stiffness (5-spoke, NACA profiles).
	Comète Track: “ultimate aero” design and speed retention (convex lenticular, dedicated carbon structure).
	Ellipse: regular training + racing, a robust and practical solution (welded Maxtal aluminum, flip-flop).

Question 9

What axle standards should I check for a track bike?

Accepted Answer

On the track, many setups typically use 9x100 at the front and 9x120 at the rear. The iO and Comète Track product pages list these axle sizes (front 9x100; Comète rear 9x120). Always check compatibility with your frame/fork before purchasing.

Question 10

Why does the Ellipse have a “flip-flop” hub?

Accepted Answer

The flip-flop allows you to mount two sprockets (two gears) and quickly switch from one to the other: very useful when you’re alternating exercises (start-stop, pursuit, sprint) or when you’re sharing the track with riders of different skill levels.

Question 11

What tire pressure should you aim for on the track?

Accepted Answer

There is no one-size-fits-all answer: the right pressure depends on the tube/tire, your weight, the type of track (surface), and your goal (performance vs. comfort).

The rule of thumb: stick to the manufacturer’s maximum pressure, then fine-tune it to get a “responsive” wheel with no wobble or bounce.

Question 12

How do you maintain bearings to keep a wheel spinning smoothly?

Accepted Answer

Simple check: lift the wheel off the ground, spin it—listen for noises, feel for roughness, and check for play. The Mavic wheels mentioned here feature QRM / QRM+ cartridge bearings: when a wheel starts to lose its smoothness, this is often the first thing to check.

Question 13

What safety checks should you perform before hitting the track?

Accepted Answer

In 2 minutes:

axle bolts/nuts tight,
	tire/tubular properly seated + correct pressure,
	nothing rubbing (brake pads/calipers if present on certain training setups),
	wheel perfectly centered,
	cogwheel secured/tightened (sprocket + lockring), especially on fixed-gear bikes.

Mavic track wheels: pure speed, total control at the velodrome

iO: 5-spoke design, shaped to slice through the air

Comète Track: Lenticular Shape to Maintain Momentum

Ellipse: the reliable tool for training, racing, and repetition
