Do Ceramic Pullies Help

Pulleys are examples of what scientists call simple machines.

Do ceramic pullies help. Recently we have been receiving an increasing amount of questions about oversize pulley wheels. That doesn t mean they re packed with engines and gears. In part one of this post we analyzed oversized pulley systems and their effect on friction and shifting. If you look at the area under the power and torque curves you will notice positive gains in the low mid and high range when an nst pulley kit.

Our pulley wheels are compatible with sram shimano and campagnolo. Do i still have to wash my vehicle that has a 9h ceramic coating. Although the minimal amount of paint swapping is a nice benefit ceramic coatings do not transform the surface of a vehicle into an indestructible tank. With the ceramicspeed osps system and kcnc s being very visible in the market and recently sram introducing a 14 tooth bottom pulley for their eagle derailleurs it sure is a trend that did not go unnoticed.

A pulley is simply a collection of one or more wheels over which you loop a rope to make it easier to lift things. Coated version for even longer lifetime. Metal and abec grades etc. In addition a larger pulley wheel spins slower for a given cadence and in this case each pulley also runs on premium hybrid ceramic bearings with light contact seals and a low friction oil.

For all sram mtb rear derailleurs short or long cage 10 or 11 or 12 speed mechanical or etap select the all road bike pulleys button bar. In a nutshell yes lightweight aluminum pulleys do free power and torque. That means there s more cantilever force the derailleur has to overcome in order to shift from one cog to another. And the pulleys do hang much lower than a standard 11 11 setup.

Increasing chain length sram introduced their new eagle mountain bike group set last summer and it sure is another game changer. Yes you absolutely need to maintain a ceramic coated vehicle. But derailleur pulleys are an easy bearing application because the forces are low so you don t need to worry much about ceramic vs. Today we will look at their use in mountain bike setups and what you can expect from kogel bearings.

It just means they help us multiply forces. If you have any questions or need help identifying what ceramic derailleur pulley you many need for your road or mountain bike please call our customer service line. There are two main reasons for stepping away from the traditional 11 tooth derailleur. I remember when 50 teeth was reserved for chain rings now we.
