Hiya Folks.
I've got a SunTour Cyclone mk2 GT RD that I know is a bit bent, but it sort of works.
What I can't work out is where it's bent.
Situation: Working on my Holdsworth Whirlwind.
Rear dropout was adjusted by a good frame builder (Winston Vaz) - it's very straight.
I'm using a SunTour hanger which is perfectly flat.
I tried the Cyclone Mk2 and on the large cog the cage just pinged on the spokes but wasn't going to catch so trimming made it ok.
Got a Cyclone Mk1 and there's now 3mm of space between the spokes and the cage on the large cog.
So Mk2 is about 4mm more towards the spokes than it should be.
.
I knew it was slightly bent - I've got another Mk2 on my other bike and that's definitely straighter - but this meant I could measure it.
I don't want to remove the new RD so here's the Mk2 in question on a spare frame (1982 Avanti):
And here's the SunTour Cyclone II GT diagram:
So my guess is that this Mk2 was in a collision and is bent somewhere, but I can't see where.
Anybody know where they bend ?
