Thank you guys for all your input, I do appreciate it!
ISIS is not compatible with RF 30mm Cinch. Two completely different interfaces.
Best is to go with a spider made by the crank maker, specifically for that crank. Direct mount possible?
Thanks for the clarification, I now understand that ISIS is not the same as BB30.
Does Cannondale make spiders for standard chainrings with different offsets? I can't seem to find the right one... :-(
I've never tried to set up a C'dale crank on another bike, but some thoughts.
If a 160 spindle with 0mm offset chainring works on a Fat Caad, a 166 spindle with an "AI" ~3mm offset ring should work too.
As an option, take a look at the Garbaruk chainrings that have so-called variable chainline technology (VCLT) -- i.e. more negative offset the smaller the tooth-count.
I'd also get a pile of 30mm spindle spacers in different widths, so you can adjust/tune the spacing and chainline as you need to with whatever bottom-bracket you end up with.
Thanks for the info!
I can't tell you what's going to work on your frame. I used the 166mm spindle on three different bikes and they all used a different offset spider. Farley 8 (old 177mm frame) took the 6mm offset. Bucksaw (177mm frame) took the 3mm offset. Motobecane Sturgis (197mm frame) took the zero offset. I also have a Famed full suspension that needed the 169mm spindle and a 3mm offset. I went with the narrowest Q factor I could get on all frames. I have one zero offset and a couple 6 mm offset OneUp Switch CDale spiders in my stash I'll let go.
Interesting, I don't know why they all need different offsets, but this topic makes my head spin anyway...
I can't find a SWITCH Spider for CD with 3mm offset at any vendor, knowing my luck, that will be the one I will need...
Would you mind sending me a PM regarding the two Switch CD spiders? You are located in the US, right?
That Hope BB will work. I used the Cane Creek Hellbender in my 121mm PF BB
Thanks, are we talking about this one? I think that is bit too pricey for me. :-/
Are there any decent alternatives to the Hope BB? I have a hard time finding BB30 PF for 121mm Fatbikes - but again, this stuff is bit over my head...
Thanks, they are a tad cheaper than the orignal ones from CD, but since I have to send one back anyway, I think I'll stick with a local vendor that carries both the 160mm and 166mm.
Those Miranda cranks seem to be a dead end, can anyone make sense of that video? Could I use a BB30 spindle from Cannondale
with that?
I already wrote to their support, but I likely didn't do a great job describing what I am looking for.
I got an email from AB, they only sell CD chainrings with 3mm offset, so if I need another one to get the right chainline, I am out of luck!
Maybe I should buy the WT oval chainring with their CAMO system, I really like the option to get a stainless steel chainring, but their different ovality doesn't sit right with me, as I want to eliminate all kinds of minor causes of further knee issues, and I assume the proper ovality is one small piece of that puzzle. Of course that is all theoretical in the end....
