Description

Ride the bike that our boy Izaac Kennedy races! The Chase ACT 1.2 (Advanced Carbon Technology) frame continues where the ACT 1.0 left off, winning races around the world. The ACT 1.2 has already won the biggest races over the past few years, including the USABMX Pro Title with Connor Fields piloting his bike to one of the year's biggest payouts! Plus Joris taking out his 5th USABMX Pro title!

For 2023 and 2024 Chase has released new colours adding to their appeal and in our opinion, this frame has one of the best finishes of any race frame we sell here at LUXBMX.

For the 1.2 update, the Chase frame utilises todays most advanced technology to manufacture a BMX racing frame that can not only take the power of the worlds top Pros, but deliver the perfect feel and that is not too stiff. We took the best of the best, the ACT 1.0 and made it even better with the ACT 1.2 with small, but significant improvements.

Features
  • UD carbon monocoque frame. Uni-directional carbon has one of the highest tensile strengths of any carbon fibre, so the frame is strong without being too stiff.
  • Integrated tapered head tube. 1.5" OS at the bottom and 1-1/8" up top, both running reinforced alloy cups in the carbon.
  • Press fit BB86 bottom bracket. A reinforced alloy cup at the pedalling end, and the 1.2 update opened up chain clearance for larger gear ratios.
  • 20mm dropouts, two tensioner systems. Extra length reinforced stainless steel dropouts with internal and external chain tensioners, plus a 10mm (3/8") axle adapter in the box.
  • Aero seat post, internal routing. Chase aero seat post with an integrated quick release clamp, brake cable run inside the frame and recessed brake bosses.

BMX race bike sizing

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

SizeRider heightTop tube
Micro (18" wheels)Under 110cm16.25"
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.
