Is Shimano Deore XT the same as XT?

Deore XT carries the big advantage of having the Shadow Plus technology (link), unlike the Deore which in the best case has the Shadow compact design. Simply put, the XT works faster, more accurately, more silently and doesn’t need regular service for adjustement.

Are all derailleur pulleys the same?

The pulleys that will actually fit on your derailleur are determined by the generation of your group set. This is a number stamped on every part and goes by a four digit number. For instance any number between 9100 and 9199 indicates the latest generation Dura Ace.

Are oversized derailleur pulleys worth it?

But oversize pulley wheels actually offer enough of an advantage in wattage savings that it may be worth sacrificing style. The big idea here is to reduce friction in the drivetrain. Fewer watts wasted as you pedal mean more efficiency and speed.

What do oversized derailleur pulleys do?

Kogel: The main goal for an oversized derailleur cage is to reduce drivetrain friction. Larger wheels require the chain to articulate less. Bending a chain causes friction between the plates. By making the wheels larger the chain needs to bend less every time it runs through the derailleur.

Is it worth upgrading jockey wheels?

While well-serviced jockey wheels can work for years, there will come a point when these workhorses will need to be replaced. If the teeth on your jockey wheels are heavily worn, then this can negatively affect the quality of your shifting as the teeth can fail to engage.

Are ceramic pulleys worth it?

In testing conducted by CeramicSpeed, its own pulley wheels with ceramic bearings proved the most energy-efficient, consuming 0.033 watts. Or, in other words, this was the amount of energy lost in transmission.

How many watts do oversized pulleys save?

Your choice, your advantage 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.

Is Shimano XT good?

The Deore XT 2020 groupset is a confident update to an already great product. With its huge range and 12-speed gearing, it’s shifting is market-leading, yet it sits at a reasonable price for the level of performance and weight. In short, it’s one of the best examples of mountain bike drivetrains.

Are oversized pulleys faster?

Additionally a larger pulley wheel rotates slower than a smaller wheel, reducing bearing speed and therefore bearing friction. ‘ ‘A well-designed oversize pulley arrangement will also allow for customisation of the cage’s backward spring tension,’ says CeramicSpeed’s Paul Sollenberger.

Are bigger pulleys better?

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.

What are the benefits of oversized derailleur pulleys?

Are all Shimano jockey wheels the same?

They’re both 11t. But on stock Shimano pulleys, the upper and lower wheels have a different profile. The lower wheel has shorter teeth than the upper one. The KCNC doesn’t seem to differentiate between upper and lower wheels.

Does oversized pulley work?

‘Larger pulley wheels decrease the amount of articulation required from the chain links,’ says Ard Kessels, founder of Kogel Bearings. ‘As friction is created through chain plates sliding back and forth when articulating, there is less friction created when the chain moves less.
