It was only a matter of time before Radio Raceline started to produce complete race bikes to shake up the traditional race bike market, The Radio Raceline Quartz Pro XXL is the third size offered in the 3 bike Quartz range. With a Pro XXL+ top tube length at 21.75 inches, this lightweight hydro-formed frame is spec'd with some very impressive parts like the Radio Solar carbon fork and hydraulic disc brakes. We've seen nothing for 2021 that comes even close to matching this race bike on both frame geometry design and materials utilzed. Add to that that Radio have nailed the colourway and graphics and we'll be lucky if any are left by the time you finish reading this description!
The vital stats are listed below, but make sure you click on the specification tab to drill down into what makes this bike unique in the sub $3000 race market. We've been building custom race bikes for a number of years now at LUXBMX, and we can hand on heart say, you wouldn't get anything near the level that this bike straight out of the box. Bolt on your clip pedals and tear out the fastest hill times you've ever done. The Radio Quartz is that good!
