Do Ceramic Pullies Help

There are two main reasons for stepping away from the traditional 11 tooth derailleur.

Do ceramic pullies help.

Metal and abec grades etc. 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. That doesn t mean they re packed with engines and gears. Pulleys are examples of what scientists call simple machines.

It just means they help us multiply forces. Yes you absolutely need to maintain a ceramic coated vehicle. In part one of this post we analyzed oversized pulley systems and their effect on friction and shifting. 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.

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. Recently we have been receiving an increasing amount of questions about oversize pulley wheels. Today we will look at their use in mountain bike setups and what you can expect from kogel bearings. Our pulley wheels are compatible with sram shimano and campagnolo.

That means there s more cantilever force the derailleur has to overcome in order to shift from one cog to another. But derailleur pulleys are an easy bearing application because the forces are low so you don t need to worry much about ceramic vs. 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.

Coated version for even longer lifetime. If you want to lift a really heavy weight there s only so much. In a nutshell yes lightweight aluminum pulleys do free power and torque. 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.

Increasing chain length sram introduced their new eagle mountain bike group set last summer and it sure is another game changer. Ceramicspeed ceramic pulley wheels offers smooth and precise shifting and less drag. 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. The dyno charts consistently prove that lightweight pulleys improve power torque and response across the entire power band.
