my bike has been making some annoying noises recently, i have identified where they are coming from, but im not sure how to fix them.
1) there is a rubber seal on the non-driveside of my rear hub. when the wheel is spinning the seal spinns with it, and squeeks. if i touch the seal while the wheel is spinning, i can stop it from turning, and the squeeking also stops.
2) the rear derailleur bottom pully (the sproket, jocky wheel, whatever the terminology) squeeks as it turns. what kind of lube should i use to stop it? i imediatly though to use a teflon based spray lube, but im not sure if this is a good idea. its an ultegra derailluer BTW.
how on earth do i solve these irritating noises?!
