7 speed vs 8 speed vs 9 speed
Posted: Thu Jul 31, 2008 12:15 pm
The beast needs a new chain, I guess that one from Kmart isn't really up to it for a rider like me.
Current configuration
53 chain ring - near new 105
39 chain ring - long in the tooth
7 speed cluster on 9 speed shimano spline wheel, on its second chain
Friction shifters, not indexed.
Chain is slipping on the 53 chain ring, not slipping on the 39 or the cluster.
Options
1. Purchase new 7 speed chain + 39 chain ring. Risk being that 7 speed cluster may slip and need replacing. Advantage is that if I get around to fixing my 7 speed wheel, I can continue to use it.
2. As 1 + 8 speed cluster. No mucking around with potential hassles related to different wear rates in components. Spare 7 speed (broken) wheel goes on council collection.
3. Purchase 39 chain ring and use new 9 speed SRAM chain and 9 speed Tigra cluster that I have sitting in a box at home.
4. As 3, except I take my used 9 speed chain and Ultegra cluster off the OCR and put it on the beast, putting the new stuff on the OCR. OCR has near new 53 and 42 chain rings.
Ratios on Tigra and Ultegra clusters are identical.
Question: How does 9 speed go with non indexed friction shifters? is it too sensitive?
