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
