How Does Ceramic Speed Make You Faster

CeramicSpeed technology focuses on reducing friction and producing bearings with an unmatched lifetime, meaning that you get to ride faster or save energy. Those savings increase further with the use of a CeramicSpeed UFO Racing Chain. This will save between 2–5 watts, taking your competitive advantage up to 14 watts.

Does CeramicSpeed make a difference?

The data. CeramicSpeed claims the OSPW can save you between 2-4W over a stock Shimano Dura-Ace derailleur cage system (at 250W, 90rpm), and that figure progressively improves the worse your chain maintenance and selection of chain lubricant is (or as it wears off and gets contaminated toward the end of a race).

Are CeramicSpeed pulleys worth it?

Based on the data, the CeramicSpeed pulley is the most efficient pulley, consuming 0.033 watts/set. The results showed the Shimano Acera as the least efficient pulley of the group, consuming 1.370 watts/set. The difference between the most efficient and least efficient set of pulleys is 1.337 watts.

Are CeramicSpeed bottom brackets worth it?

The highest performing ceramic threaded bottom bracket outperformed the highest performing steel threaded bottom bracket (made by Hawk Racing) by less than 1%. The highest performing bearing made by CeramicSpeed was outperformed by the Hawk Racing steel bearings by almost 15%.

Are ceramic jockey wheels worth it?

According to research, a well-made ceramic bearing will roll faster, saving you energy and allowing faster cruising speeds compared to an equivalent steel bearing. This is because the properties of ceramic allow the creation of rounder, smoother bearings.

Do pros use oversize pulley?

If it sounds like we’re only focusing on CeramicSpeed, there’s a good reason for that. Few other companies are offering oversized pulley wheels and its OSPW are, by and large, the pulleys of choice in the pro peloton. And the pulleys do hang much lower than a standard 11/11 setup.

Are oversized pulley wheels worth it?

‘Larger pulley wheels decrease the amount of articulation required from the chain links,’ says Ard Kessels, founder of Kogel Bearings. Additionally a larger pulley wheel rotates slower than a smaller wheel, reducing bearing speed and therefore bearing friction.

What do oversized pulleys do?

Oversized Derailleur pulleys improve the performance of your stock derailleur cage. Oversized pulleys do not require a new chain – Since the added length in the chain is only about 2 teeth, typically you can run oversized pulleys without having to replace your chain.

How many watts does an oversized pulley save?

The Oversized Pulley Wheel System It sells for $499 and is claimed to save you at least 2.4 watts.

How long does a CeramicSpeed bottom bracket last?

CeramicSpeed bottom bracket and wheel bearings should be maintained every 5,000-8,000 km or 3,000-5,000 miles. CeramicSpeed headset bearings can be maintained once per year for most riders.

Which bottom bracket is best?

Best Bike Bottom Bracket [Review] in 2021 Best All Round Bike Bottom Bracket For Cycling. Wheels MFG BB86/92 Shimano Bottom Bracket. Shimano Dura-Ace BB-R9100 Bottom Bracket. Shimano Tourney TX BB-UN100 Cartridge Bottom Bracket 68/122.5mm OEM. Shimano BB-UN55. SRAM GXP Team Bottom Bracket.

Are Kogel bearings worth it?

Kogel sell the highest quality ceramic bearings for the both very low friction and durability. A cheap ceramic bearing is often worse than a decent steel bearing. We carefully selected to offer Kogel bearing upgrades for 3 main reasons.

How many watts do ceramic jockey wheels save?

CeramicSpeed technology focuses on reducing friction and producing bearings with an unmatched lifetime, meaning that you get to ride faster or save energy. With CeramicSpeed products in your hubs, pulley wheels and bottom bracket, tests show that you’ll save between 6–9 watts, compared to using standard bearings.

What is a disadvantage of ceramic bearings?

Ceramic bearings have lower load capacities in comparison to metals and are sensitive to thermal shock. Thermal shock is when the temperature gradient within the material causes a differential expansion, which results in an internal stress. This stress can exceed the strength of the material thus forming a crack.

How much faster are ceramic bearings?

He says ceramic bearings are said to be three to five times harder than steel bearings and, as a result, can withstand the force applied to them through chain tension and pedalling for longer.

Does the size of the pulley matter?

A larger diameter pulley wheel (aka sheave) is technically more efficient than a smaller diameter pulley. But it’s a trade off: a larger pulley has increased bulk, weight and cost. This efficiency increases with really big loads (600 lbs+) and larger mechanical advantage, such as 6:1 and 9:1.

Does derailleur pulley size matter?

Pro road racers who use Berner’s uniquely oversized rear derailleur cages have sworn time and again that they reduce drivetrain friction thanks to their humongous 15-tooth pulleys.

Does a smaller pulley spin faster?

A larger pulley turning a smaller pulley results in the smaller one turning faster but with less shaft power. For example, a truck in high gear would have a slower turning engine but faster turning wheels, resulting in a faster truck.

Do oversized jockey wheels make a difference?

In real-world testing conditions, oversized pulley wheel systems have been proven to increase the efficiency of the drivetrain when compared to standard pulley wheel systems.

How do pulleys affect torque?

How does pulley size affect torque? The ratio of the pitch diameters is called the drive ratio, the ratio by which torque is increased and speed is decreased, or vice versa. Pulleys do not effect power; when they increase torque, it is at the expense of speed, and vice versa.

What is OPWS?

How many watts do carbon wheels save?

The Session’s Carbon Wheels are ready for tubeless and additionally are wider, enhancing this effect further. In a headwind, the profile wheel with the widest tire, saved 9 watts. But as we have already presented here on the Session Blog, the candle effect will save an impressive 20 watts in the cross winds.

Do you need a longer chain for OSPW?

A standard chain will be long enough to fit the new OSPW System. You will need to remove fewer, if any, links when installing a new standard chain.
