[FONT= Verdana]Hi CyclingForums![/FONT] [FONT= Verdana]I've been commuting on a second hand raleigh for a few months now, and have recently taken it to pieces to clean everything up and get it rolling a bit smoother.[/FONT] [FONT= Verdana]Having done so, I replaced the chain and rear derailleur as they were rusty and now have a problem with my gears slipping when I pedal hard on the smaller sprockets of the cassette...[/FONT] [FONT= Verdana]I have taken a few snaps of it and wanted to know if I should consider replacing? I've spent a while adjusting my old and new rear derailleur to get the slipping to stop to see if it was the fact that i changed the derailleur, and no matter the tension of the cable, or old/new derailleur, the problem does not go away.[/FONT] [FONT= Verdana]I've done some digging on the net and found that its generally good practice to replace a cassette that has had a worn chain on it for quite some time (which I have used every weekday for the past 6-7months of ~4miles per day) Should i be changing my cassette?[/FONT] [FONT= Verdana]Thanks, [/FONT] [FONT= Verdana]Austin[/FONT]
Start by putting the bike in a workstand or trainer and looking closely at the way the chain and problem cogs mesh as you turn the pedals. If you can rule out derailleur adjustments then yes it sounds like your cassette is worn to the point where it doesn't mesh well with the new chain. You can also carefully inspect the teeth on the smaller problem cogs and if they are sharp and spiky and don't look like the teeth on the larger cogs that don't give you trouble then that's another sign that your cassette has been worn down by the older elongated chain and should be replaced.
Yes, i've spent quite a long time adjusting my rear derailleur trying to iron out this problem... I shall have a good look at the sprockets tomorrow, but its giving me trouble with all of them, bar the largest.
[FONT= Verdana]Hi All,[/FONT] [FONT= Verdana]I had delivery this morning and fitted everything a few hours ago.[/FONT] [FONT= Verdana]After a quick re-adjustment of the rear derailleur, everything is working fine.[/FONT] [FONT= Verdana]Here's some pictures for comparison with my older cassette with the new shimano HG chain.[/FONT] [FONT= Verdana]Thanks for all your recommendations.[/FONT] [FONT= Verdana]Austin[/FONT]
