I have an old 10 speed Raleigh road bike.Sure I don't expect it to ride
like new but this bike is really h-a-r-d to ride.
when I ride on a flat road or when I climb a flatish hill I feel the same resistance. I don't intend to ride centuries with this bike but after 3 miles my heart-rate jumps to 170 bpm which is irrational.
So I thought what could be the problem, chain-lube - done that
wheels- almost true, sprockets look good not worn not bent, crank is
also ok though there is a little tick at a certain point in every revolution
but the crank arms are not loose or anything and spinning freely.
So my conclusion was that the problem is with the bearings.
So for the first time Im trying to deal with this part of the bike.
I took apart both wheels and then I unscrewed the nuts until the bearings opened. (I didn't remove the free wheel bc I don't have the freewheel remover but I managed to take the balls out of there).
then I took all the balls out - 9 small balls of each side of the front wheel and 8 bigger balls each side in the back. The bearing were all
full of blackish yellow sticky old grease.I wiped with a dry cloth all the parts of the bearings and the balls too.the balls looks ok, no rust, still equally round and the inside of the bearings look ok too after I wiped all the old grease.Now I have everything taken apart and I wonder what should I do before reassembling back everything.
I have kerosene and I have a plastic box full of new grease which I just got from the garage.(this grease color is purplish black)
Any help from the mechanics here is much appreciated.
