Ok, I have two Revelation 426 dual air forks. One bought in March 2005 (I think) which lives on my P7 and one bought in about May 2007 from Merlin, which used to live on my Orange 5. Superficially they look identical but I'm wondering / hoping that the newer one has more travel than t'older, as I've got a new Orange 5 frame that's apparently optimised for a 140mm fork whilst I've always assumed that both Rev's were 130mm.
How would I tell? There aren't any markings on the forks to indicate travel. The newer fork with both chambers pumped up has slightly more fork leg showing (135mm opposed to 130mm) than the older one, but is that an indication of actual travel?
I appreciate it's not the end of the world if I'm riding with a fork that's 10mm short of 'optimal'. In my head though.....that's a different matter...
