Out of interest – my Cannondale F29 medium goes in the back of ford focus (mk3) with both wheels still on. I was a little surprised…but grateful of this, as it saves wee bit of fiddling..but in honesty removing the front wheel is quick and easy.
Love my F29 by the way, it’s exceptionally fast (climbing speed is closer to my road bike than my old 26er hard tail!) – it has that bit of comfort twang in the saddle when combined with the save seat post to make a short travel full suss almost redundant. Handling is spot on, Lefty is so precise in steering, light and with longer servicing intervals than common. The front end setup is so stiff that the only negatives I encounter is some hand fatigue on rocky trails (poss down to the stiff carbon rims).
Oh, and QR rear is a total non-issue. Its plenty stiff enough..especially with an RWS skewer.
