Darn slipping gears!

stealthbike

I can't seem to fix my slipping gears, when I'm in my lowest gear at the front and the lowest two or three gears at the back, when climbing th e gears/chain constantly slips under pressure. i've so far changed the chain (the rear cogs are still reasonably new) and fitted a new cable, but still no joy?? Could it be the rear mech? any ideas? It's only on the really low gears, drivng me mad when i need to climb.

set them up correctly? is it the free hub slipping?

stealthbike

No the chain skid sthrough/slip under weight/pressure

nicklouse

if the chain is really slipping then the cogs or the chain are worn.

the chain is the correct length?

and you are talking about when using the small fron and big rears (size)

stealthbike

Yes, small at the front, big at the rear - brand new chain - set up correctly and correct length. Maybe the rear cogs are already worn, seems odd through.

i'd suggest checking the hanger. is it true? check to make sure the cogs are tight enough on the hub.

stealthbike

i think you may be right , the hanger is knackered - does this mean a new rear mech?

shouldnt do just a new hanger BETD have lots of hangers. oR for a short time fix you could get it bent back at your lbs

when you cahnge a chain, yopu're supposed to change the cassette too.

also, could be the derrailleur pivots are worn out. i had that problem last year on my gt,. tried allsorts, but was fixed with a new mech.

no, some guys at the lbs can straighten the hanger in seconds.

get them to check the rear mech at the same time. prob charge you aournd £4-6 for that.

yea i straighten them in seconds every week and people can't believe it's so simple! you need a tool for doing it though! your lbs will go through the posibilities and tell you whats wrong.
