Quick cassette question

[RedBullet]

so i have tiagra 9 speed and the chain needs replacing so im goin to change the rear cassette, now my question. instead of getting a tiagra 9speed cassette, can i get a ultegra 9 speed? or is it not as simple as that.

 

[Dave Davenport]

Do you need to change the cassette? I go through three or four chains before the cassette needs changing.

well my chain tool says its at 0.75 so no but i feel like i should change it for what it costs. Heres another question then. i find my tiagra shifters ugly because of the exposed cable system. so could i get ultegra shifters on it (obviously 9 speed ones). is that as simple as that?

 

[DooDah]

Ultegra 9 speed shifters also have the cables out of the side. The only way to have concealed cables is to step up to 10 speed 105 or Ultegra.

ahhhhh bugger. and to tranfers to ten speed i would have to change shifters, rear cassette , chain, rear mech? , hub?

As Adrian said "Shifters, cassette and chain" rear mech & hub should be OK.

or there's always this

yes, but not hub

ok thanks for the replies, why is there a possibility i wouldnt need to change my rear mech, surely i would although i wouldnt be able to afford everything at once

 

[jay clock]

sorry, you would do only need to change mech if you wanted it to match. The older ones will work fine with 10 speed

The rear mech just moves the amount determined by the lever, it you disconnect the lever you can pull the mech to any position you require.

Indeed. The shifting may not be as smooth though, based on the 9 speed derailleur and jockey wheels being designed for the wider 9 speed chain.

The inside dimensions of the chains are the same its the outside that's different.

you might not like the cables but it has its advantages - i.e. you can change the gear cables without having to change the bar tape at the same time! Wrapping bar tape is also much easier with only one cable under it.

No worries. I just read it on Sheldon's site a little while back when a colleague asked. Never tried it myself, but that was his advice.
