Choosing Seal Type
Kogel Ceramic Oversized Pulleys come in two seal options, specific to road and off-road use. Simply choose the best seal for your riding environment from the drop-down menu on the product page.
Road seals, for lowest friction
The minimal contact seals find the balance between reducing friction losses and maintaining the “Guaranteed Performance Warranty”.
Cross seals, for best protection
The cross seals are built for the best protection. The difference in friction between the road and cross seals is around 0.5W on a bottom bracket. On the upside, bearings with cross seals are close to waterproof. If your road rides include gravel roads or if you regularly ride on wet roads or places with very fine sand, the cross seals will buy you some peace of mind.
