Seals: LLU contact seals are a closer fitting seal to rotating parts, and thus provide better protection against dirt and moisture ingress. Use where bearing longevity is more important and/or you frequently use your bike in harsh conditions. If racing or chasing watts is your priority then our non-contacting low friction seal version of this bearing (LLB Seals) might be more appropriate.

Contact Seals - The seals are in contact with the balls, so thus will keep the moisture out longer. Use these where bearing longevity is more important than low resistance. Also consider if you ride in all weather, particularly wet weather or if you fitting to a full suspension frame pivot.
