Changing rear cassette

[smilingcat]

But on rare occassions one may shift to the largest rear cog without remembering which front cog one is on. In that case, the chain would jam and it wouldn't be good. You may damage chain, derailleurs, cogs, or crash.



The cassette will freewheel in the direction you need to turn the lock-ring tool to remove the lock ring. A chain whip is required to keep the cassette from turning. To tighten the lock-ring, you don't need another tool.

Hi Deb,

Yes if your chain is too short to span the 50 tooth chain ring and the 29 rear cog, you could damage several things including the rear derailleur. so you have to be really careful about it. In a race situation, would you be using a 29 cog?? I used to use 11/19 (11-12-13-14-15-17-19) a corn cob more or less (I think those were the sizes of cogs and before cassettes) and 39/53 chainring. As you can tell I'm dating myself And if there were major climbs involved I woud opt for more normal clusters like 11/25

Maybe my memory is failing me. I haven't disassembled a bike in like 6 years or so. I quit riding back in 2001 and just started back up against wishes of my loved ones. I just take it easy these days and let LBS deal with bike maintenance.

Thanks, I wont throw away my chain whip or other parker tools. I think pedro's degreaser is still good after 6 years or so???...
