issue with derailleur since putting rear wheel back on
Dear all
not even sure if it is the derailleur really, but ever since a routine clean involving taking both wheels off and putting back on I have not been able to get a smooth run of the chain on the back cogs.
When I am turning the pedals with the bike lifted I am getting a slight bump / resisistance at a certain point. I think resistance is probably the better term as when i turn the pedals with minimal force, this resistance actually stops me turning the pedals.
Any ideas on this?
Done this many times with no issues - is it possible that I have knocked the derailleur out of allignment?
As part of the clean I ran the chain through a cjhain cleaning device as I always do, and I do not think there is a problem with the chain.
Any help would be greatly appreciated.
Thanks

sounds like rear wheel not aligned correctly in rear dropouts and rubbing against brake block and/or chainstays.0

no, its definately in ok, spins perfectly fine, the only issue is when pedaling
I have taken out and re-inserted 3 times and no improvement0 -
it must be something you can see. what gear combination are you using while spinning the wheel?0
-
smallest cog both ends, as I would be in this gear when removing and refitting wheel0

Could be a stiff link in the chain.0

You are cross chaining- most 9/10 speed bikes are not designed to run in this gear combination and the outer face of the chain will more often than not rub against the inside face of the large chainring and/or or the cage of the front mech. Sure this isn't your problem?0 -
Interesting ...........
How come I could do it then ? I must admit it seemed a lot worse on the stand and it did seem to rub on front mech
However took it for ride (ironically to lbs to get fixed ) And it was a lot better on the road so I returned home
Planning an easy 30 miles tommorow for a good test0 -
Good man.
Just avoid cross chaining as a general rule , i.e. never do it. It's unneccessary really as a similar gear ratio is always available elsewhere in a different combination. It also puts your chain at the greatest sideways deflection. Chains like to run in a straight line or as close to it as you can get.They last longer that way too.0
