Bicycle Crank Bearings,Bicycle Cartridge Bearings,Ceramic Bicycle Wheel Bearings,Bicycle Wheel Ball Bearings - PYC

PYC bearing is a specialized manufacturer of bike bicycle crank bearings,bicycle cartridge bearings,ceramic bicycle wheel bearings,bicycle wheel ball bearings.

The speed of a bicycle is most determined by the performance of its rotating parts. This makes bearings a logical choice for upgrade, as they are facilitate the rotation of cranks, wheels and gears. Ceramic bearings enjoy a host of benefits over their steel counterparts:

Integrity - Ceramic bearings are 10 times rounder than steel bearings and 20% more rigid. No part of the bicycle is subjected to more intense physical conditions than bearings, increased stuctural integrity in the bearings leads to a more efficient bike.

Durability - In various tests, ceramic bearings have been found to be 5-20 times more durable than steel bearings. So if your steel bearings typically last 3-4 years, ceramic bearings should last a minimum of 15 years.

Weight - Ceramic bearings weigh 40% less than steel bearings. Weight savings are most beneficial on rotating parts, nothing on your bike rotates faster than the bearings.

What do these numbers mean for a rider? Well, FSA did some testing and found that a bike equipped with ceramic bearings was 4% more efficient than the same bike equipped with steel bearings. So for every 100km ridden on the steel bearing equipped bike, the ceramic equipped competition rode 104km, while expending the same amount of energy. If we assume the peloton averaged 40km/hr, that's a win by.....SIX MINUTES!
