Description

The DK Zenith Disc race frame is back for 2022, and back in black! This frame forms the foundation for the DK Zenith complete race bike. If you are going to build up a brand new race rig for 2022, you can be assured that this race unit is designed with the same proven low-profile geometry as the DK Professional-X frame to help you produce maximum speed, but retain stability right from the 20.5" Pro, up to the 22" Pro XXXL sled! This frame has cemented its reputation for winning since its introduction in 2020, being engineered from the ground up for acceleration. DK, a trusted name and a favourite here with the LUXBMX crew, these are one of our picks of the alloy frames for 2022.


This frame is 100% custom design constructed from 6000 series hydroformed aluminium. Patent pending sliding flat mount disc brake system delivers superior braking in all conditions. Clean, compact, responsive, and stiff, with a wide stance rear end designed for max power. The neat and tidy design of this disc system helps keep it away from the front wheel of those wannabes dive bombing you in the last corner trying to wreck you. Fools! They never had a chance.

Features
  • Hydroformed 6000 series aluminium. A 100% custom design in lightweight alloy tubing, with a wide stance rear stay design that adds stiffness where you put the power down.
  • Sliding Flat Mount disc brakes. The patent pending system delivers superior braking in all conditions and keeps the calliper neat, compact and tucked in tight.
  • 30mm of axle adjustment. Horizontal sliding 20mm and 10mm dropouts let you set the rear end where you want it, with integrated chain tensioners holding it there.
  • Tapered 1-1/8" to 1.5" head tube. The headset is included, along with an extra lower race so you can still run a standard 1-1/8" fork.
  • Race ready through the middle. Threaded Euro bottom bracket shell, internal brake cable routing and a trapezoidal seat mast for extra stiffness at the bottom bracket.

BMX race bike sizing

Race frames are sized by class, and the class you ride is set by rider height rather than age.

Mini (20" wheels)110 to 125cm17 to 18"
Junior120 to 140cm18.25 to 18.75"
Expert135 to 155cm19.5 to 19.75"
Expert XL150 to 165cm20 to 20.75"
Pro160 to 170cm20.25 to 20.75"
Pro XL165 to 175cm21 to 21.25"
Pro XXL170 to 185cm and up21.5 to 21.85"
Pro XXXL175 to 185cm and up22"
Pro XXXXL185cm and up22.5"
Cruiser (24" wheels)175cm and up21.5" and up

Heights overlap between bike sizes on purpose. If you fall in two size categories, a growing rider new to racing is usually better suited to the larger bike, a experienced rider who wants the bike to more responsive should err on the smaller size. Some brands label the Pro size Pro L, with the same fit.

How to measure

Stand your rider against a wall in the shoes they ride in, heels flat, and mark the top of their head. Measure from the floor to the mark. Just don't guess their height either, you know how fast they can grow!

Here are some tips

  • Between two sizes and still growing? Take the larger size, but make sure you check the top tube length of the bike. The length of top tube for a given size (Expert XL as an example) can vary up to a half inch or more across brands. Most Expert XL frames are 20", but we've seen them as long as 20.7"
  • Experienced racer and wanting the bike to be more responsive? Take the smaller size. You want the bike to be "under you", not a stretch to the bars and cranks.
  • Top tube is the number that actually changes the fit, so compare it against the bike they ride now.

Still not sure? We're the experts and size bikes for riders every day of the week. Our team has decades of experience between them and will help you decide which bike is the right fit based on rider height and racing experience.
