change cassette and der
I wish to change to a Shimano Megarange cassette (11-34) (knee
problems dontcha know) on my road bike. How do I check whether it will fit? Also I'll need a long cage der. What is the simplest part to substitute for the Sora 8 unit. Advice please. TIA |

What is the simplest part to substitute for the Sora 8 unit. Advice please. TIA If you've got an 8spd shimano-compatible hub now and you're putting on an 8spd megarange cassette, it will fit. If your chain is the correct length now, it will need to be lengthened/replaced (replacing the chain along with the cassette is generally good anyway). With some exceptions you probably won't encounter (Saint and Hone), any current or recent Shimano SGS (long cage) derailer can be swapped for your Sora. Closest comparable quality would be Alivio. Note that the Shimano mountain sgs rear derailers with the big pulleys have the same capacity as normal looking long-cage derailers, they just go about it differently. If you have a mid-cage (gs) rear derailer and a triple crank now, understand that all that happens when you exceed it's capacity is that you get chain slackness/rub in the small/small combos. But if like most riders you only use your road bike's small ring with the biggest couple cogs, it's not an issue, and med cage is actually somewhat preferable. If you have a typical double (up to 16t difference), you'd only need a med cage rd, not long. |

TIA Deore long cage rear derailleur..get a new chain whileyou are at it as the old one is probably too short..least expensive compatible chain. The cogset, an 8s, will fit onto the hub fine. |
