Upgrading components...(4 posts)

Upgrading components...DT
Mar 14, 2001 3:05 PM
I'm looking at buying a used GT ZR 5.0 for my wife...can the 8spd Sora freewheel, shifters and derailleurs be upgraded to 9spd stuff, or would I need to get new hubs also? Thanks!

I think only Tiagra and up can be interchangeable. Sora has different shifters etc. I'm not quite sure, but that's what I read in the Shimano catalog. I think it would be better to get 105 for your wife. It's almost as good as DA and is quite cheap. Better value than the Sora which I head broke down more often.

Ya need rear 9 speed shifter but it wont match the ergonomics of the sora front, so ya may as well buy both. 9 speed cassete, chain and maybe inner or middle chainring,and maybe front derailer to make things work really swell.Why not just save some hassle and spend the money on a cheap 9 speed bike.The 8 speed hub will take a 9 speed cassette ok.

The high and low gear will be the same. That's kind of a lot of money to spend to get one more gear on the back.
