WTB: Suntour Cyclone GT long cage

[Eric Marth]

Hello friends — On yesterday's ride I broke one of the tabs on the chain tension spring of my Cyclone rear mech. 

If you have a long cage Cyclone you'd part with please let me know your price shipped to me in Virginia, 22401. 

Thank you!

Here you can see the spring and the bright metal from the fresh break. I even found the little piece of spring that broke free.

Wonder if you can bend a new tab on the end of that spring to make it work? 

Thanks,

Reginald Alexis

Hmmm...let me dig around in my parts box.  I have at least one Sun Tour RD in there, but it might be a short cage.  But you could take it apart - the spring should be the same.

I'll PM you with my findings.

@Eric

Echoing George's comment, my local bike non-profit has a handfull of old Suntour derailers(ARX, XC, XCE). Happy to send any/all you think might be worth a look for parts harvesting. swinging through there today to grab some stuff for a project. let me know!

Like Reginald suggested, I bent a new tab onto the end of one of those springs a year or two ago. It has held up so far, but the derailer is only in use as a tensioner on a dinglespeed. Getting the bend angled so that it would go back together correctly was a little bit of a nuisance, but if nobody has an intact derailer for you, give it a try.

Thanks all! I have heard from several people now, here and outside the forum, who have suggested bending a new tab. I saved the spring so I'll give that a try. 

Drew: As far as I know the Suntour Cyclone Mark 1 short and long cage used the same cage tension spring. I'm not sure if the ARX, XC or other mechs would have a compatible spring. So I'll pass on those, but if you find a Mark 1 short or long cage, I'm interested!

Eric - I've viewed the photo of your Cyclone GT as closely as possible.  It appears to be completely identical to the short cage Cyclone that I have available, the only difference being the lengths of the derailler cages.  Therefore, if you can't get that spring fix to work the simplest repair would be to use the derailler I have and just change out the short cage for the long one on yours.  The advantage these Sun Tour deraillers have over some other makes is that the cage arm fastens directly to the spring body vs. having the spring assembly bolting to the jockey wheel.  You can have mine just for the asking if you decide to go that route.

Great, thanks George! I'll send you an email here shortly.

Thanks to everyone who reached out about Cyclones, I'm all taken care of.
