Alright the bike is a brand new cannondale f7 blew out the 2nd rst fork in a month
The local shop i bought the bike from wanted to sell me a tora 302 u turn 80-130 mm adjustable. I ended up getting a recon race air with 120mm travel.
Now After getting it installed i was told my warrenty is no longer in place for the frame. Overall The fork is under 3/4 of a inch longer then my rst 100mm with out me on the bike. But on the bike the rock shox a pop loc that no matter what i will sag around 10mm even locked out making the fork exactly the same length as the rst ive measured with both installed.
So what added stress will i have with this on my frame? and I dont understand now why the warrenty will be void when they wanted me to buy the tora in the first place?
