Enjoy your new lines of research!! 😉
If you want to reduce complications, go SS 😉 Although you’ll still have to deal with the wheel minefield… Just wait for the tyres!! 😆
Presumably, you’ll be riding XC, with very little gnarr, drops, jumps n ting? In which case, hubs can be either Hope with cartridge bearings, or Shimano with cup and cone – your choice/preference. Rims can be anything really, as you know, light wheels are better. Im 10.5st ish and use Stans Crests with Hope hubs in both 32hole and 36hole and both sets cope really well with everything from South Downs stuff to Alps. Mavic rims work, Ive had some X317’s and X717’s in the past and again, both worked well and stayed true. Ive no idea if they’re available new, but two more products for you to research up on and you’ll find plenty second hand for sale.
There are many other wonderful hubs, Chris King, DT Swiss etc. You pays yer money, yadda yadda.
To start your off road experience with a Ti HT is a very nice way to start and you’ll get lots of feedback and responsiveness from that frame, money well spent. 8)
