How awesome does this look! And best of all, it's available right now on the website. We've built the dream Pro XXL race bike based on the much sort-after Wiawis Atom-X frame, and it's ready to hit the track straight off the shop floor. Check the photos, then scope the spec sheet and you'll appreciate that there's nothing on this build that you would need to change. Starting with the Wiawis Atom-X carbon frame and fork manufactured utilising Graphene Nano Technology. This allows the frame to be built extremely light, yet strong enough for the demands of elite BMX racing. You will see the team from the UCI World Cycling Centre on the Work Cup circuit on Wiawis bikes, an arena that really tests the integrity and strength of any BMX frame and fork.
The details of this build start from the ground up, with Spectre carbon rims and Spectre titanium spokes laced to Onyx hubs. A Helix 20mm up front, and the ubiquitous Ultra SS out back. You'll spot that this is disc hub and we've mated it to a SRAM TLM hydro caliper and lever to make sure you can pull up pretty quick if someone drops it in front of you. Moving through the drivetrain, 180mm Avian Cadence cranks are called upon to handle the extreme stresses placed on this component, with Shimano's DXR pedals bolted to them to complete the power delivery. Up top, the over-sized Pride 8.25in Renaud Blanc 373 HD bars have a 3 degree sweep to keep the bike shooting straight down the hill which are connected to the forks via a Pride Cayman 58mm stem. All in all, we've drawn upon our years of race experience to save you the time, and head scratching, to pull all the parts together for a killer Pro race bike.
