I want to get into bikepacking. I currently have a 2009 Rockhopper Pro.
I am curious if the stock 28/32 Specialized Hi Lo hubs and DT Swiss 445d can hold up on the GDMBR. If not advice on upgrading would be nice, wheelsets are my least knowledgeable area. The specs on the Hi Lo:
I'm thinking your wheels and hubs will be fine, but you might want to start researching tubeless setups. Some Specialized wheels come "tubeless ready", with blue tape inside the rim to seal the spokes. Yours may already be setup that way if the bike came with a pair of valve stems. Search the forum here for more info on tubeless setups. If your rims are already taped, the Specialized "2Bliss" ready branded tires like Captain Control would probably set up very easily. Some of the TD racers here run tubeless, then carry spare tubes with stans sealant inside to use along with a tire boot if the tire gets cut and cannot seal itself. I believe Jill Homer ran the TD using slime tubes as a primary flat avoiding setup. In any case, reasonable volume 29er tires setup tubeless with 22-30psi depending on your weight, handling preferences, etc - should give a relatively comfortable and flat-free ride.
