Is there a single source that lists, and can be used to identify, makes and models of freehub?
I have a couple own-branded hubs that I would like to replace the freehubs on, so I can upgrade from 11 to 12 speed but I can't find what make they actually are.
I don't want to replace the wheels as that would be an extra expense that I can't really afford at the moment, and they are fine anyway, so swapping out the freehub seems the obvious choice, but I can't find any way of identifying them. I can only stare at so many photos of freehubs before losing my mind!
The hubs are GT and Sonder Love Mud branded. I have contacted Sonder and they weren't able to help and haven't yet contacted GTs owners.
Any help with suggestions on methods of IDing them would be appreciated, ta.
It's likely you are stuffed unless someone has worked it out or you get lucky. Assuming you have HG freehubs one option is to use 12 speed cassettes with 11t max that will fit on the existing freehub (instead of the 9/10t max that need XD or microspline).
Cheers, @nixie, I had a feeling that might be the case. I was hoping to either microspline or XD to get the smaller sprocket otherwise there's no real benefit on the HG they both currently have.
You might get lucky with the sonder wheels as I think they were sold with XD or HG option. Sometime might have time it wasn't too swap.
As for making the 12s change pointless that depends on your current cassette. If you would be gaining a lower heart (day 52t instead of a 46t) then you could increase your chainring size by 2t and end up with both a higher and lower min/max than the 11 speed setup has. It's likely you'll need a 12 speed chainring anyway.
I recently helped a pal replace the freehub on a sonder wheel and it was a bit of a chore. For a few years their wheels used screw-in freewheel mechanisms rather than a standard freehub. Not a serviceable part, and needed a 14mm (!) hex key, cone spanners and a bearing press to replace. Worth emailing sonder to figure out which wheel you have (they’ve changed design a couple of times) but if you’re unlucky the cost of parts, tools and/or labour might make freehub replacement uneconomical.
EDIT: sorry, just saw that you’ve emailed sonder already. I guess the first diagnostic could be ‘can you remove the freehub by hand’ ?
FWIW one of the bigger importers i used to deal with had near enough 100 different freehub options across 8 brands of hub (4 or 5 of which that were manufactured by the same 2 factories in Taiwan and labelled up differently).
Even the hubs manufactured in the same factory were 50:50 on having different freehubs to do the same job.
And that was when we only had Shimano and Campag spline patterns, and 11 speed was just a pipe dream...
So a freehub picker is a long painful nightmare...
