I wonder why nobody tries 115mm Reba on Rush. Is it too short? keeping in mind cdale uses 120 Fox
Given that a Lefty 110 is 20mm shorter A-C than the Fox 120 and in 07 Cannondale specced the Fox 100 I am sure that you could use a Reba 115 on a Rush frame. I think you only see the Fox because the Rush Z series use that fork.
