Give your GF the short travel sus and you take the Hardtail. 26″ wheels will be more fun
Not really an option, don’t want to give her a bike she’s never ridden before really. Also, it’s possibly just a tad long for her, my hardtail is on the cusp but have a feeling asking her to ride the full sus she’d feel a touch stretched. If anything, I probably have as much fun, if not more, on full sus these days anyway. Unless the trail is really flat and boring of course, in which case I’d always take my hardtail out, but I expect Glentress is going to be anything but flat and boring!
So, the lightest thing you’ve got. With the smallest wheels, so your mid travel bouncer.
Reading all the above posts, I was kind of coming to that conclusion I must say. 5″ of travel and sub 28lb should probably be alright, have a feeling that a 35lb bike with almost 7″ of travel would probably start to feel a bit too much like punishment after 3 whole days riding…
