I took a punt on some Reba RL forks which were going cheap, they've arrived and look in great condition, but have 120mm of travel and I was hoping they were the 100mm model. Having fitted them, they are a bit long for my frame, can I take a spacer out and/or fit a shorter air tube to both drop the front end and reduce the travel? The serial number stars 28T10... which I presume makes them a 2010 fork?
