old broken shifter...need help...

[paddleknut]

....gotta fix it cheap. I need the outlet of riding cause with a new baby I don't have time to head to the rivers to kayak....and it keeps me sane an hour at a time.

so I have an old cannondale from '94 or '95 I'd guess. The deltavee frame, light and stiff..I love it. Has a 7 speed rear cassette and I've busted the shifter. It is one of the two lever styles with a push and a pull and it mounts to the same clamp the brake lever is on. Nearly everything these days has a 9 speed cassette...will a 9 speed shifter work on a 7 speed cassette? Can I spread the rear triangle to accept an upgraded cassette? What are the chances of finding a used shifter that will bolt right on? It's deore lx by the way.

Thanks,
matt

I bought some new 7 speed shifter/levers last week: Shimano EF-50. There are 7 speed cassettes and spin ons (freewheels) avaiable from Shimano too.

Don't know if either of these will fit the bill or not:

Probably can locate some used on e-bay but no guratnee as to the condition.

You should not spread your frame ... aluminum frames are not very forgiving enough in that regard.

You CAN probably use a 9-speed shifter with a 7-speed cassette ... others may disagree!

The anchor plate on most Shimano rear derailleurs allow for two different anchoring positions -- one attaches the rear derailleur cable at 6 o'clock (the "normal" position ... the factory-engineered alternate position at 9 o'clock will modify the indexing.

7-speed & 8-speed cassettes are fairly close in spacing, so if you were to install a 9-speed Shimano shifter AND use the alternate anchor position, then you should be able to mate everything in a workable configuration ... that is, 9-speed shifters with your current 7-speed cassette. You will, of course, have two extra index "clicks" ...

Either a 7-speed & 8-speed shifter should work without changing the rear derailleur cable's anchoring. Some people disagree.

If you are moderately patient, you should be able to find a used 7-speed shifter on eBay ... AND, you may be able to find a NEW 7-speed shifter on eBay, too ... simply input "Shimano right" into eBay's search box.

Found a link to the 8 speed, however they come in 7 speed as well: http://harriscyclery.net/page.cfm?PageID=49&action=details&sku=LD8919
