Upgrade to 12 speed

[Bo6]

I am looking at upgrading my Q45 to 12 speed and using a 10-50 cassette to get a wider range. Is there a Scram XD driver that is compatible with the stock Chosen hubs?

@Robert Holler in a previous thread he was going to ask the supplier which freehub/driver is compatible.

Thanks, did a bit of a deeper dive into it and Scram does list "Chosen" as a compatible brand.

Chosen *does* make a hub that is XD compatible - but it is a different hub model than the one we use - which is a standard 9/10/11 speed hub.

Thanks,
I know that Chosen hub are very hard to find, but do you know the model # of the hub? I may have to caibalize my 12 speed Scram NX mtn bike to give the 50 tooth rear a try. Lots of hills around here that are too tough for my old legs and the stock gearing.

I put an 11-51 cassette on my Q-45 with a wolf tooth for the derailer .I changed my front chainring to 34 tooth .I still have the 11spd shifter .I have some 12% grades where I live .I can grind up them without stopping,It still takes body conditioning but it does help

I'd like to know too. I've been unable to source an XD compatible hub that's a 135 QR. I've concluded that if I want to upgrade to the XD, I'll need to also upgrade the front triangle to a thru axle 142 width

Did you consider sticking with the HG hub and using an 11-50 12 spd cassette?
