SwishTi Titanium Bicycle Bike Rear Derailleur Oversized Ceramic Pulley

TITANIUM MATERIAL

Titanium is a strong and lightweight refractory metal.

Titanium alloys are critical to the aerospace industry, while also being used in medical, chemical and military hardware, and sporting equipment.

Aerospace applications account for 80% of titanium consumption, while 20% of the metal is used in armor, medical hardware, and consumer goods.

Alloys containing titanium are known for their high strength, low weight, and exceptional corrosion resistance.

Despite being as strong as steel, titanium is about 40% lighter in weight.

CERAMIC BEARING

Bearings are typically steel or ceramic.

Both have their advantages (cost vs. quality) because steel is cheaper than ceramic, but ceramic is known to be higher quality and less maintenance.

Ceramic bearings are harder than steel bearings, they are more durable, lasting anywhere from five to 20 times longer.

Besides,ceramic bearings are lighter,because ceramic is less dense than steel.

In summary, ceramic bearings cost more not only because the balls are ceramic, but the overall quality is better.

An additional benefit of ceramic bearings is its inability to rust.

In the conclusion,ceramic bearings are the best investment for everyday and/or high impact rider, but steel bearings are great until wanting to take on the investment.

OVERSIZED PULLEY WHEEL

The Bigger Pulley to upgrade the riding performance!!

Let chain angle getting smaller, improve the shifting smoothly.

Resistance is smaller, gain the power more than usual.

Ultra Light&Strong Titanium CNC Machined.

NARROW-WIDE
The term "narrow wide" describes the shape and profile of the individual teeth driving the chain.
Each tooth alternates thickness, narrow wide narrow wide, all the way around the pulley.
With an old school traditional pulley, all the teeth would be considered narrow with small differences in thickness between brands.
When looking at your chain, you will see how each link is pinned together to the next and the gaps between chain links alternate from narrow to wide.
The narrow wide pulley now mates seamlessly with the chain, almost locking the chain to the ring without much increase in drag.
Besides,as you ride over rugged terrain, your chain moves around quite a lot.
The sole purpose of the narrow wide pulley is chain retention.
The narrow wide tooth pattern keeps the chain from moving left to right and eventually popping off while riding.
No one likes to drop their chain on the trail, especially in a race scenario where every second counts!
In addition ,narrow-wide helps to clean muds more efficiently.
It is also important for these narrow wide pulleys to be able to shed mud and grime to function properly.
