First Generation Cyclone how many cogs can I get it to shift?
 

I've got a nice 7 speed cassette I'd like try using. It has a 25 tooth rear cog and from what I understand the Cyclone can only do 24...It probably could work okay right?

Has anyone got experience using the early Cyclones with a 7 speed. I'm sure It could do 6 without a hitch but 7 might be pushing it. If that is the case I've got a Suntour VX-GT that could do it all.

I'm really wanting to trim weight. Currently my "price point" Masi is using a Shimano Acera...You know what it shifts pretty damn good but saving a few extra grams wouldn't hurt :)

I currently run 45-42 / 13-15-17-20-23-26 with a Cyclone. The ultimate capacity depends on your chainring size difference, your rear wheel fore-aft positioning, and your derailleur hanger (I need to use a "claw" on this particular bike, the UO-8).

Don't know about Cyclone, but the Suntour Superbe I had on my Mondia would only shift to 26 teeth. I went to a Shimano Light Action, and while it was spec'ed at 28 teeth max, it went to 30 with no issues.

Try it and see. Swapping a RD is pretty easy, and you'll find out prety quick that way.

It'll cover all 7speeds no problem. And you should be able to go to 25t. I forget what the spec is for the first gen Cyclone short cage at the moment, however I think its listed on VeloBase. Beyond that, a Cyclone GT will certainly solve all your problems! :thumb:

Sutherland's says for model RD-6000 that with 26 mm hanger offset, chainring diff./max. capacity/max. freewheel is 14/24/25. With offset of 30, it's 14/28/26
