I have a 2012 Flash 29er Alloy 2, which has the Lefty 29'er PBR, 90mm, OPI, Solo Air (according to the C'dale website). I'm going to do a bearing reset, and I just found out that there are spacers in there that reduce travel to accomodate taller wheels/tires of 29er. Was thinking of removing 1 of these to increase travel. Is there anything else that I'd need to do to increase travel (other than making sure that I'd still have enough tire clearance at maximum travel)?
