Highlights

  • Pro XL, 21.5 inch top tube
  • Carbon HSX geometry in alloy
  • 6061 T-6 hydroformed butted tubing
  • Fixed 15mm thru-bolt dropouts

Description

This HSX frame is the aluminium version of the extremely popular Meybo carbon HSX that mimics the geometry and specifications of its more expensive sibling, with only a very small weight penalty. So small that when built, the difference would be negligible.

Sitting around half the price of the carbon frame, the Meybo HSX alloy frame doesn't sacrifice in the way of features. Manufactured from 6061 T-6 multiple butted hydroformed tubing and utilising the same fixed dropout system and flat mount disc caliper set up, it brings to the gate the same simplistic design that has seen the HSX series become popular on the UCI circuit. And not just favoured buy the Dutch, riders all over the world appreciate the ease at which gearing changes can happen. 

We love these Meybo frames for their simple clean graphics that state perfectly their no nonsense approach to winning. Touches like full internal cable (hose) routing makes building these frames up child's play. Plus it looks so clean! Make no mistake though, the HSX range has all the attributes of dialed geometry, stiffness and proven on the track performance. 

This aluminium HSX frame isn't the poor cousin of the carbon frame, it's an astute choice for the racer that will likely put the savings towards other key performance components such as carbon fibre rims and Onyx hubs to build a top shelf BMX race bike capable of competing at the highest level of BMX. 

The 2025 HSX alloy frame could be the smartest choice when building a high end race rig as the savings over its carbon cousin can be dropped on a wheel upgrade. And after building a number of HSX race bikes for customers over the past few years, you'll be pleasantly surprised by how quickly, and easily these frames build up.

  • Carbon HSX geometry in alloy. Mimics the geometry and specifications of the carbon HSX for a weight penalty small enough to be negligible once built.
  • 6061 T-6 hydroformed butted tubing. Multiple butted hydroformed alloy brings the dialled geometry and stiffness of the HSX range at around half the carbon price.
  • Fixed 15mm thru-bolt dropouts. The fixed dropout system makes gearing changes easy, one reason the HSX is a favourite on the UCI circuit.

BMX race bike sizing

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

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.
