FYI: Out of the box Reba travel is 100mm
This may be obvious to some of you, but I could not find a definite answer on the travel a brand new Reba (the non U-Turn models) has.
The best info I found seemed to think it was 100 mm with one spacer pre-installed and one spacer included in the box (to drop it to 85 mm). That's what I expected, but I was further confused when my Reba arrived with two spacers in the box. That made me think it was shipped at 115 mm. I ended up tearing down the fork to verify. Despite shipping with two additional spacers, one spacer was already installed for 100 mm travel. Given the earlier posts I read and my own experience, I'm relatively sure all Rebas ship at 100 mm travel.
Again, it may be obvious, but I wanted to post something others could find easily if they have the same question.
