Its hard to tell exactly because I can't find the bike you are looking at for certain. Is it a X-lite Ultegra? Rose is claiming a weight of 6.8 kilo while I see the Canyon Ultimate CF SLX 8.0 also with Ultegra is coming in at 7.2 kilo. The Canyon's frame is lighter buy 80 grams (780 versus 860) and the wheels on the Canyon weigh 1450 grams where the DT swiss on the Rose weight 1585 grams.

My Aeroad weighed exactly at the claimed 7.1 kilos when I weighed it at home. So if the Ultimate in Ultegra is truely 7.2 and you add the extra 205 grams in for the added frame and wheel weight, the rose would have to shave over 600 grams on the rest of the bike and seeing how they both have Ultegra groups, I don't see that being true. Without going over piece by piece on everything and comparing the rest, I call BS on the claimed weight of the Rose. The bars, stem, seatpost and saddle for instance didn't look all that light to help make up the 600 gram difference.
