Gustav Gullholm, aka Dangerholm<\/a>, has been crafting some of the most unique and lightweight bike builds for over a decade. The Swedish custom bike builder is known for his one-off creations, refinishing and speccing out bikes with carefully curated selections of some of the lightest, most exotic \u2014 and most expensive \u2014 components on the market. Ten years after turning his first Scott Spark RC into the \u201cworld\u2019s lightest 29\u201d full suspension mountain bike<\/em>,\u201d Dangerholm has a new ultralight build on the latest version of Scott\u2019s XC race platform<\/a>.<\/p>\n

Over the years, Dangerholm has built numerous Scott Spark RC bikes<\/a>, including 3rd- and 4th-generation frames. But Dangerholm says the 5th-generation Spark raises the bar for XC even higher with its suspension performance, geometry, and light weight. So, he set out with the goal of turning the latest Spark RC frame into a sub-9kg complete build that was not only light, but also fast, fun to ride, and pleasing to the eye, too.<\/p>\n

\u201cI started with setting 9kg \/ 19.84lbs as a weight goal for the complete bike. Partially as a fun challenge, but also since I personally find that it is around this weight and below that you truly start to notice a big difference and really feel that you\u2019re riding a superlight bike. With the low frame weight and lightweight components available today, this is a relatively easy weight target as far as tuning goes, but the real challenge lies in getting there without compromising performance or durability.\u201d<\/p>\n
