I hope you find a buyer, Ahmed.
I hope folks realize that the Hillborne was sort of the bike that started the whole modern era of Rivendells, as I don't feel like the Hillborne gets as much regard as the newer, evolved models. The Bomba came first as a 6 degree upsloping tubed bike, but the Hillborne was the first of the Taiwan expanded geometry bicycles that have come to exemplify Rivendell (this is according to my fuzzy memory). It was meant to be a do all, beat it up, ride it like crazy, never repaint it (I recall grant saying he hoped nobody would ever repaint one), and pass it down to your children bike. I honestly think anyone looking for a Riv and fits this 55cm Hillborne couldn't find a better bicycle. I have had a super secret 56cm double TT Waterford Hillborne since 2011 and it is a never sell for me. It was my primary touring bicycle for a number of years, also commuter, shopper, and do all bicycle. It can use drops or uprights. Folks seem to want a Riv mixte or droptube, and I have had both and sold them both because I never actually used the lower tube for stepping "in" to the bicycle, I still throw my leg over, and with the expanded geometry of the Hillborne, you don't have to worry about standover anyway.
Also, and this is again only my experience, I never got along with the long wheelbase that the newer Riv's have. I much prefer the ride of my old style Atlantis, Hillborne, and Simpleone.
I hope this helps anyone on the fence.
