Ceramic Pulley Position

The result is faster smoother shifts and a quieter drivetrain.

Ceramic pulley position.

In our experience these are the best shifting after market pulleys available past or present. The stud has a d fitting that mates with a d shape recess in the body. Ceramic rubber pulley lagging is especially suited for drums with slippage and excessive wear tear problems which make normal rubber lagging ineffective. Upgrade the bearings and use a larger slower spinning lower pulley you can t put a bigger one in the upper position.

Each kcnc pulley wheel is equipped with a high quality hybrid ceramic cartridge bearing. Pulley position the purpose and position of a pulley in the conveyor i e. Drive tail bend or take up impacts how much load the individual pulley will experience while in operation. This is largely due to the.

A quick spin test immediately raised doubts as to the quality of kcnc s bearings sram s pulleys also with ceramic bearings had much less drag. Originally launched in 2016 with 11 teeth per wheel the new 12 tooth derailleur pulley wheels keep the quiet chain friendly delrin composite construction and free spinning ceramitech hybrid ceramic bearings. The other method is to directly bond the ceramic tiles to the pulley shell. Extensive testing has shown the oversized pulley wheel system does reduce friction and increase shift efficiency and therefore the low friction bearings should save you watts.

There s two ways to reduce pulley drag. This movement allows the pulley to settle into an optimum position under each cassette cog. In general pulleys in the position of driving the conveyor belt will experience greater loads than pulleys in other positions. Further conveyor design transition distances and drive traction should.

The body must be rotated to one position only before the cage can be removed. The result is faster smoother shifts and a quieter drivetrain. But so should having a professional bike fit to dial your riding position or shaving your legs and losing 5 kilos. Falling material and hard objects caught between the lagging and belt are the usual cause of this issue.

Kcnc ceramic derailleur pulley wheel kcnc pulleys are intentionally designed with an integral amount of float or lateral movement. The pulley cage is held to the body with a stud pressed into the cage. There are a few issues with ceramic lagging. Ceramic can be fragile and prone to cracking.

Note position of cage to derailleur body in this relaxed position. This movement allows the pulley to settle into an optimum position under each cassette cog.
