Just added the 180mm OneUp v2 dropper to my new XL Trek Rail that came with 130mm, way too short of a drop. Works perfectly with full 180mm (no adjusters in), maybe 15mm above lowest position. I am 6' 5" , but not so long in the legs. A great upgrade, and easy to do.
Sounds like a deal. If I could get that price it would make finalizing my purchase decision much easier. Rail 7 is in my sights even without a great sale price.
Also 6'5" here (is that 'very' tall? :), and am a bit concerned with fit. Body dimensions make a difference as some tall riders have a lot of leg and others like me have a lot of torso length. I think I'm looking for a large reach, and maybe a shorter dropper post and some rise in bars/stem...
Doing my due diligence before plopping down the serious $$ for an EMTB. Currently looking at the Trek Rail 7, Giant Rein, and Specialized Levo Comp. Difficult decision ahead. It's Winter here in Montana, so have a couple months before it makes any sense to buy. Plenty of time to research...
