Here's a Ridley Helium SL road bike for sale. as you can see in the photo, the bike weighs 6.39 kg. i rebuilt the bike but never rode it because various personal things came up. In the meantime, I just want to get rid of a few road bikes, of which I have too many. Size: S / 545mm, so in fact size 54. The frame is a team frame from the former Team Lotto Belisol, weighs a real 780g. I bought the frame as new, it was only mounted once, according to the dealer. The derailleur group is used but in good condition. The crank bearings run smoothly. The wheels are used, built up with acros nineteen hubs and a Shimano 105 cassette (11-28). The add-on parts (ritchey carbon handlebars, Syntace stem, carbon seatpost from Rose and san Marco carbon saddle) are all new and only fitted for the build. Crank: Campagnolo Super Record with titanium axle 50/34 chainrings and a length of 172.5mm With a lighter wheel, you can easily break the 6 kg barrier and end up with 5.xx kg. So if you're looking for a lightweight road bike, you'll find it here.
