Mstategfr, In MEC (for you us folks, MEC is Mountain Equipment Co-op, very similar to REI) They offer bicycles ranging from mountain bike with dual shocks all the way up to racing road bikes. They do offer a specific bike designed for touring with full panniers both front and rear. its nice to have everything all ready and set up with out any fiddling and modification. I asked about that bike and checked the website for reviews, it seems very positive.

As for LHT, from what I know, its a build a bike type of system. I have to inform the salesperson that i want this, that, and whatnot, and they will build a bike that meets my expectation. but I've noticed that surly LHT is very well liked by many tourers. yes I also am aware that schwalbe is the best brand of tire for touring due to it durability and strength to last for thousands of miles vs generic type of tires. As of off road, I was just wondering that due to GDMBR, I am aware that GDMBR is an off road type of route mostly on single tracks and gravel roads, and I was wondering is it possible to use a road type bike on this route, or should i consider using a dedicated mtn bike and go on GDMBR.

Thanks everyone, keep the feedback coming.
