which wheel has two different size bearings in Taff ?

never changed front bearings whats the best way ?

jsp

The rear has 2 different bearings, the 6004 is thicker but be carefull the thin 6905 bearing was also in a thin bush which came out as I drifted the bearing out, make sure you dont throw the bush away with the old bearing and refit the bush before you fit the new bearing.

The front wheel bearing change is really easy, knock the inner sleeve between the bearings down then drift the bearings out, to refit I think it's a 32mm socket is the right diameter too knock the bearings in with. Some people flick the bearing covers out and repack the bearing with grease I've tried this but the bearings never lasted any longer so I don't think its worth the hassle. Front bearings can be changed easily within 1/2.

Hope this helps.

Thinking about it I reckon my rear hub was a Friday afternoon one ! it has a sleeve because if was machined over size and has had a repair done on it !

sounds simple enough, ive always packed the new bearings with grease

when ive done the back ones, and i also do it everytime i have the wheel

out, but never changed the front ones. and i havent changed any on the

ossa. order my new 6905 from ak, i had some 6004 in stock as there the

same as most bikes

I dont know if the wheels are different to the 2011 but Bill was machining them to take proper size bearings that will last.

to be honest i dont think mine are doing that bad as

i ve had it since september and this is only my first

set, and it gets ridden at least once a week come

rain or shine, and i m a clean freak !!!

bearings came yesterday, waterproof marine grease came

today, all bearings packed with grease from both sides and

fitted. jobs a good en

Where do you guys ride , to have SO MUCH bearing problems ?

WOW ! 2 rides ? ? bearings shot ? ? ? I've only EVER changed wheel bearings on ONE bike , after FOUR years of riding , I thought THAT was bad.

Where do you guys ride , to have SO MUCH bearing problems ?

In lots of water sections and then there is all the cleaning using chemicals and power washers.

I ride prob 40% of the time in/around creeks , pressure wash(I make sure to avoid seals) EVERY time I clean it.

That much bearing problems is amasing.
